Insensitive / TSS^

No, it's not a "someone made an inappropriate remark" story! It's another power meter, cycling training item. So for those non-PM using readers who's eyes roll around the top of their head when I go on about this stuff, then you can look away now :D .....

There have been lots of comments lately on the Google groups wattage forum about the Normalised Power (NP) algorithm and whether it could be improved. The discussion, as they often do, has drifted a bit from that into - "could the Training Stress Score (TSS) metric be improved?"

Well can they? Possibly.
Should we bother? I'm not so sure it matters.

Maybe it's because of the insensitivity of these things. Lemme show you an example.

I have produced a standard Performance Manager Chart (PMC). It covers my riding since I started back on the bike last year (~ 7 months).

As an experiment, I decided to add onto it another version of the PMC, with data based on an augmented TSS (TSS^). In this case, the calculation of TSS is not a function of the ratio of NP to Functional Threshold Power (FTP) but expressed as a ratio to Maximal Aerobic Power (MAP).

Now there is no particular reason for doing it other than curiosity, nor would there be any great sense given the underlying physiological and other rationale for choosing FTP as the anchor point. But that's not my point. It's an experiment to see what it means, from the point of view of how we actually use the information to monitor and guide our training.
MAP for most people is typically 25% +/-3% higher than FTP and so by anchoring an augmented TSS calculation to MAP instead of FTP, that will of course change the way TSS is calculated (since now I get a much lower weighting for threshold work and have to exceed MAP for gains to be multiplied).

And the impact of changing the TSS calculation? Well that'll change the PMC and how we interpret our training, right? Well, maybe.

Here's the PMC chart with two sets of lines for ATL, CTL & TSB. Default time constants used. One is based on TSS, the other (right hand axis) is based on the augmented TSS, “TSS^”. As always, click on the pic for a closer look.



Anyway the fact that the augmented ATL^, CTL^ and TSB^ mimic the same patterns, just with different absolute values, should not be a surprise since there is a reasonably consistent relationship between FTP & MAP.

Of course the relationship between FTP & MAP does vary (which it has during the period in the above chart), and when it does there will be deviations (as can be seen in the different slopes of the CTL and CTL^ lines).

But even so, just look at how closely the TSB and TSB^ lines track each other. Yet I have changed the TSS weighting formula quite a bit by anchoring to MAP instead of to FTP.

So if I showed you those charts independently, and multiplied the right hand axis values by two, you simply would not know the difference and it certainly wouldn't provide any different or additional insight into what was going on with my training.


So what would a PMC look like using these other “improved” formula for NP and/or TSS? That's what I'd like to see. Can it really provide us with a better insight into what's going on with our training?

I suspect all the mucking about with alternative NP or TSS formula would do is simply produce slight variations in the PMC (maybe absolute numbers a little different here and there) but the underlying training patterns that emerge would be the same and the interpretation would be the same. And even if the patterns are different, we still have to look at them in the context of the composition of our training, rest of life factors etc just like we do now (or should do).

Basically the modelling is pretty insensitive.

But let's see some examples folks....

I'm always open to looking at things in different ways to help garner additional insight.

Quadrant Analysis

Earlier I posted about a thought I had - to do a Quadrant Analysis (QA) on the power meter data from my Threshold Tolerance Intervals (TTIs), comparing TTIs done at my local training ground, Centennial Park Sydney, to TTIs done on my home trainer, Thunderbird 7.

Funny, in the several years I've been posting about power meter stuff, I haven't mentioned QA. Yet it is one many funky tools to help explain some the differences in the physiological demands of different types of rides.

I don't really have to go into much detail to explain it, since it's already been done by Dr Andrew Coggan and you can read all about it here.

But the short version is that QA is useful for examining the neuromuscular demands of a ride. Essentially it plots pedal forces versus pedal speed (the combination of both equaling power) for each data point recorded by the power meter. In this way, we can not only see how much power we produced during a ride but also gain additional insight into how we produced that power.

There are a number of ways such a plot can be used (e.g. examining and/or comparing ride data with your maximal pedal force-pedal velocity relationship) but I'll leave that for another day.


OK, so the plot is shown above. Let me run you through it:

- The vertical axis is Average Effective Pedal Force (AEPF - measured in Newtons)

- The horizontal axis is Circumferential Pedal Speed (CPV - measured in metres per second)

- Plotted in little red and blue dots/circles are the AEPF and CPV for each second of power recorded by the power meter. The data is from the "on" parts of my intervals only, that is just the time I spent at the intended effort. There is 40-minutes of data for each group.

- The green curved line shows the point at which pedal forces and pedal speeds, when combined, equal my Functional Threshold Power.

- the vertical and horizonal purple lines delineates the quadrants and represent 90rpm (with a 175mm crank) and 167 Newtons (or the same as applying a force of ~ 17kg).

The four quadrants represent:
I - high pedal speed & high force (e.g. sprinting at high speed)
II - low pedal speed & high force (e.g. hard efforts, such at track starts)
III - low pedal speed &low force (e.g. just noodling along at low rpm)
IV - high pedal speed & low force (e.g. spinning fast but easy downhill)

We plot AEPF and CPV, since from a neuromuscular point of view, what's important is both the force and speed of muscle constractions/movement. Investigating either AEPF or CPV in isolation from the other is a fairly pointless exercise. (Refer Pithy Power Proverb "Cadence is a Red Herring" - R. Chung).

We can only plot AEPF, since each point of power meter data covers one or more revolutions of the cranks, in other words, the average of the forces applied to the pedal for an entire rotation of the crank. What this doesn't show is the variability in forces applied around the various points in the crank's revolution. As we know though, the greatest forces are applied on the downstroke, and by a happy coincidence, the maximal force exerted on the downstroke by each leg is roughly double the AEPF*.

* post edit: it was pointed out to me by Robert Chung I had expressed this relationship incorrectly (I had said "the maximal force exerted by one leg is the roughly the same as AEPF") and made this correction to show what I originally said as well as what it should have said.

CPV is basically similar to pedalling cadence, so why don't I just show cadence instead, since most people can related to what 90 rpm is like? Well in this case, the crank length on each bike is different. On the road bike I have 175mm cranks and on T7 I have 170mm cranks. So at the same cadence, the CPV would be higher on the bike with longer cranks. Or for the same CPV, my cadence would be slower on the bike with longer cranks.

If however you were examining ride data from rides using the same length cranks, then certainly you could also show cadence.

OK, so what do we make of the plots of my TTIs?

Well the first thing is that the dots are quite tighly grouped near the centre of the chart, which is pretty typical for efforts of a time trial nature. Generally the flatter the terrain, the more tightly grouped the dots will appear for a quasi-steady state effort. This contrasts significantly to plots for track races, criteriums and rides over hillier terrain, where the dots are widely scattered around the chart. In rides like MTB, the technical nature of riding can see a rider bumping up towards their maximal AEPF-CPV curve quite frequently.

The next thing is how much more tightly grouped the blue dots (indoor trainer) are compared to the red dots from the outdoor ride in the park. This shows that while the average power from these efforts was very similar, there were still differences in how I produced that power in each case.

We can see that the dots are close the the green line (denoting a pedal force/speed combination at FTP) and that the effort, overall on average, was just below my FTP.

The red dots tend to parallel the shape of the green line, which is reflective of me seeking to maintain power within a desired band over slightly variable terrain (I think the total altitude change is ~ 16-18 metres over the course of a 3.8km loop, with a few ups 'n' downs along the way). My speed varied significantly with the terrain and my cadence varied as well, although not by as much as speed since I would change gear regularly.

So, when riding on a trainer, there is a tendency for the AEPF-CPV relationship to show more of a rifle like plot during such Threshold Tolerance effort, whereas outdoors on more variable terrain (and conditions) the plot looks a little more like it came from a shotgun, albeit it one with an odd shaped barrel!

Is it important?

Well it simply serves to show that similar efforts can have variable neuromuscular demands and even changes as small as this may affect the power one is capable of producing in a given scenario. It just emphasises the specificity principle.

If your time trials are outdoors, makes sure you do some time trial training outdoors and ensure your legs are ready for the more variable neuromuscular demands.

Smith & Wesson

The indoor training Gods have spoken.

This morning was meant to be my Threshold Tolerance Intervals (TTIs) - the good ol' 2 x 20-min workout at near FTP. Target range at the moment for me is 91-96% of FTP (250-265W).

So I drive to park today, hop out to attach my leg and get bike ready, Sam was riding past and sees me so stops to say hello. I get my leg on and roll off, intending do a roll for a lap or two with Sam before getting into it. But of course after 3-min a spoke goes "ping" and that's was it, wheel not in a trainable condition unfortunately. Hop back in car and go home.

So I hop onto Thunderbird 7 instead.

Last week I did my TTIs in the park at 259W and 255W.
On T7 this morning: 258W and 266W.

I intend to do a Quadrant Analysis plot of the indoor vs. outdoor TTIs and post about that soon. I suspect we'll see the difference akin to the mark on a target made by a rifle and a gunshot.

Turbocharged Training

There's been a bit of discussion lately on various training forums about a topic that seems to crop up every so often. It's a perennial favourite. Certainly I'm not the first to write about it and I won't be the last.

Why is my power different when training indoors* compared to when I ride outside? And what can I do about it?

* Indoor training being training done on an ergobike, or with the bike locked into a turbo trainer or riding your bike on rollers. Often performed inside the house, in the garden shed or garage, on a balcony or at the local gym or training centre.

Usually people train in such a fashion because they either haven't the time or opportunity for a ride outdoors, they might be recovering from injury and/or need the controlled and safe environment an indoor trainer provides, or the riding conditions outside are not suitable (cold, rain, snow, darkness and so on). Certainly riding indoors is a safe and excellent training alternative when heading out the front door on your favourite steed is not possible.

For many riders though, they find generating power indoors much harder than when riding outdoors and end up riding at a lower power as that's all they can do (but this is not the case for all though, and some can actually produce more power indoors than outside, although that is less common).

So if I can't generate the same power, then am I getting the same training benefit?

And if power is significantly different indoors, should I use a different FTP for indoor rides (so training levels and ride data are adjusted accordingly)?

Well the answers are not straightforward but let's explore the solution(s).

The first thing to do is to understand why a difference in power production exists. Then the second thing is to take steps to address the differences between each scenario and "bridge the gap". Finally, one then needs to make decisions about how the data from their indoor training should be interpreted.

So why is it common for power to be different?

There are four main factors at play here:

• Cooling & air flow
• Inertial load
• Motivation
• Adaptation

I'll explore each of those in a bit more depth a bit further down.

OK, so what about the training benefit and setting of FTP?

Well power is power and if you are burning kJ at a lower rate, then the metabolic adaptations relating to that will be correspondingly different. So if turning out a lower power really concerns you, then the priority is to address the factors that influence indoor power production and reduce the gap so that training can still be done within the intended training level. Then the problem goes away.

Nevertheless, "hard is hard" and "alls you can do is alls you can do", so if you are unable to address/fix the key reasons why power is less indoors, then set your training at a level that is attainable for that scenario. It's better than staying on the couch. Rather than worry about what percentage of FTP or MAP that should be, just use previous indoor workouts as your guide. That really should be the guide anyway, irrespective of mode of training you are doing.

What matters is that you do the workout at around the right intensity for the right duration, rather than the precise wattage.

What about FTP, and the calculation of TSS and the other metrics that flow from it?

This really is an issue of what you are training for and where the majority of your riding will be during the course of that training period. If the trainer only represents a minority of your ride time and your power is say 10% less on the trainer, then it only represents a small difference in the calculation of overall training load. It is simply not worth the bother to have separate FTP values and calculations. The Impulse-Response model (aka the Performance Manager and the metrics CTL, ATL and TSB) is fairly robust. It is about the forest, not the trees.

For example, let's examine a common hour-long training ride and say, for whatever reason, your indoor power is 10% less than outdoors: 2 x 20-min at FTP + warm up and cool down.

Outdoors, this would accumulate ~ 85 TSS and indoors (with ~10% less power), ~ 70 TSS. A difference of 15 TSS (which is about the equivalent stress of 15 minutes of endurance level riding).

So if the difference in TSS calculated from a 2x20 workout (equivalent to about 15-minutes of basic endurance level riding) is concerning you, then sit on the trainer for another 15-minutes.

If however, the trainer represents (for that training period) a large proportion of your training time, then setting FTP according to that training mode makes sense. But where such rides are only occasional, then there really is no reason to worry about minor variations in the numbers, just move onto the next day.

The same principles apply if talking about training at altitude (occasional change in altitude vs. a lengthly block at a different altitude) or different bikes (occasional or lengthly training blocks on a given bike/position).

Read on for more details on the four elements of indoor training that affect our ability to produce power indoors and how you might do something about it.


Cooling
People consistently underestimate the cooling needs when training indoors. There's some weird theory that a large pool of sweat forming beneath you is a good thing. All that tells me is that the air flow and cooling arrangement is perhaps inadequate for the task. A body that is under stress and not being adequately cooled will underperform.

Keep in mind that the typical cyclist operates at around 21-22% efficiency (give or take a couple of percentage points). Cycling efficiency is a measure of the ratio of energy reaching the cranks of the bicycle as a proportion of the total energy metabolised*.  In other words, to generate 100W at the cranks, our bodies are metabolising energy at the rate of 100W / 21.5%  = 465W.  

So of that 465W, 100W is converted to mechanical energy at the cranks, with the vast majority of the balance being converted to (waste) heat, with a bit used of course to run the rest of the body's functions.

What that means is that for every 100W we put through the cranks, roughly another 360W are generated as waste heat. How much heat exactly will vary depending on the individual's efficiency level (typical range is 19-24%).

So if for instance you are doing some intervals at 300W, you are in effect pumping out the heat equivalent of a 1,000-1,200W electric heater!  Now do you see why we heat up so quickly when training hard and an effective cooling system is required?  Especially if the ambient temperature is quite warm to begin with, and particularly so if the conditions are humid.

When you hop on your bike for an endurance ride, you have a ~ 30km/h wind flowing over your whole body constantly wicking sweat away and keeping you cool(er). So why would you expect to perform as well indoors with no air flow, or the piddling excuse of a breeze that comes from a domestic fan? Get real. If training indoors is going to become a sizeable chunk of your training time, then get some decent cooling happening and have some strong air flow over you. A large industrial strength fan costs much less than a trainer or rollers, so bite the bullet and sort it. But be prepared for the additional noise.


Some people do perform indoor training in quite cold environments, so of course they might be able to get away with less air flow than others.

* there are a couple of different efficiency measures (e.g. gross and delta efficiency), but for all intents and purposes, this basic definition will suffice in this context.


Inertial load is the next main differential factor when comparing indoor and outdoor training. Without going into too much detail, when we ride outdoors, we have the inertial load of a bike and rider moving at some speed, plus that of the wheels turning. If we stopped pedaling, our rear wheel doesn't suddenly slow or stop turning, we would coast for quite some time. On many trainers however, since we are not moving, the inertial load is much less and confined to the rear wheel spinning and any small flywheel that the trainer has attached to the roller. When you stop pedaling, the wheel slows and comes to a halt relatively quickly. Some are worse than others.

Now what happens is each scenario feels quite different to ride, muscle activation is different, the neuromuscular demands are different and these can be enough for some to make power production much harder. In general, low inertial load trainers tends to emphasise the "dead spots" in the pedal stroke (when the cranks are passing through the 12/6 O'Clock position), whereas riding with a higher inertial load enables one to breeze through (and not waste effort on) the dead spots and focus on the downstroke where the bulk of power is produced.

Fortunately there is a way to increase the inertial load of a trainer, and that's by having a flywheel attached to the trainer's roller (or even by adding mass to the wheel itself). How much mass is needed? Well to replicate the inertial load of a rider, it would need a very heavy flywheel spinning very quickly. Think of a 20-30kg flywheel spinning at 500-800 rpm. Yikes!!


Fortunately, for effective training, going that far is not really necessary and having enough rotating mass to help smooth out those dead spots is enough. I don't have one myself but trainers like the Kurt Kinetic Road Machine or the 1-Up trainer are an excellent example of this. They both have small but effective flywheels attached to the rolling mechanism.

These are ideal options for those that are looking to attach their existing bike to a trainer but also need some portability with their indoor unit.

The other option is a dedicated ergobike like the Schwinn or Saris indoor trainers (or other similar machines). These types of set up have the advantage of being able to incorporate a much larger and heavier flywheel than a turbo trainer. They are of course dedicated units and need a permanent place to live.





















So what does one do? Well if cooling has been sorted, and power is still down, then consider the inertial load of your trainer set up. Does it have a flywheel? Can one be added? Should I look at an alternative trainer? Certainly I would recommend trying a trainer that has a decent flywheel to see how much better it is to ride.Edit note: I added the following paragraph in March 2011 as something I'd been meaning to do for quite some time, just had forgotten to do it.
I should add that the idea of inertial load on an indoor trainer affecting pedaling isn't actually backed by evidence other than anecdotal, from myself and many others I know that have used such trainers. As an example, this link to a study extract on PubMed indicates that varying crank inertial loads has little or no effect on steady state pedaling coordination.


Motivation is a big issue in training and racing, and it is sorely tested when riding indoors. Many find training indoors mind-numbingly, excrutiatingly boring. Then there are others who really love it and are happy to spend hours tapping it out, sometimes preferring that to a ride outdoors. Each to their own.

If a lack of motivation is an issue, then it needs to be addressed, otherwise don't waste your money on a trainer you won't use. It'll just end up gathering dust in the corner of the shed.

There are many ways to overcome any motivational challenges you face:

Variety - there are lots of training workouts available, so keep the variety up. Dream up some of your own!

Duration - indoor riding is hard work, there's no let up or coasting, so don't make the workouts as long as you might ride outdoors. It is better to complete a shorter workout and want to come back for more next time, than to get off absolutely hating it and sitting out the next one on the couch or staying in bed.

Set Challenges - set yourself targets for the session and maybe have reminders of your goal event in front of you as well.

Music - this is a good one - having you favourite training tunes blasting away, or on your iPod to keep the neighbours happy.

Video - what about watching highlights of your favourite stage race or one-day classic. You can be smacking it up Ventoux with the Pros. Of course there is a big market out there for indoor cycle training videos, so if that floats your boat, then go for it!

Computer aids - there are lots and some of the favourites are heart rate monitors, spped and cadence measurement computers and of course my favourite - power meters. These are especially helpful so that training is focussed and performed at the right intensity.

Ergo controllers and virtual riding - there are many trainers that can automatically control the resistance level of the trainer and be pre-programmed to control a workout. Some can even display video of an animated figure or some real life video to provide a distraction from the effort and help to pass the time.

Of course the most obvious answer is simply to HTFU.


Adaptation is the last of the four key issues. Since there are differences in riding on a trainer to riding outdoors, some of which have been discussed already, then it stands to reason it will take some time for the body to adapt to training under different conditions. If you only ride the trainer occasionally, then you may never fully adapt to being able to generate power similar to outdoor riding.

However, if you ride on a trainer regularly and with sufficient volume, and you address the other three main factors, then you will adapt and improve your ability to produce power indoors and the gap to outdoor power will typically narrow.

What do I do?

Well I set about addressing all of the issues and descibe my indoor training set up here:

Swiss Watch

"The body responds like a Swiss watch. You just have to figure out how to wind it." - Dave Harris

OK, alright, I got a complaint about my blog. Like, "you haven't posted anything for ages!". Well it's been twenty days to be precise, but who's counting?

I've just been busy with quite a few things, so I'll try a catch up with this post.

Since my benefit night, training has continued along very nicely. In the first three weeks of December I have accumulated a little over 21 hours of riding and 1457 TSS with an average Intensity Factor of 0.83. That means that those hours, on average, were ridden at a level of exertion of 83% of my estimated 1-hour maximal (threshold) power.

Which is a technical way of saying very little training time has been wasted, and all efforts have been quality. Training has basically been a mixture of core endurance rides, solid tempo efforts, threshold tolerance intervals along with some track sprint work.

Here is a pic of the "thin blue line" to date:



Again, you can see the steady progression of the chronic training load (blue line) indicating the continual progressive increase in load/stress being placed on my body. The leg has been holding up well to the increase in workload and the body is also continuing to adapt. How well is it coping though?

Last week I was scheduled to do some performance tests, one a time trial effort of around 16km (10-miles) and the other a Maximal Aerobic Power (MAP) test. While not a formal test, I have also been doing some sprint work at the track to see how my maximal (neuromuscular) power is going.

First up was my time trial at Centennial Park. Here's the power file chart:



An average power of 287 watts over 26 minutes. So TT power is up 39 watts (nearly 16%) on the test I did on 23 September.

I sometimes surprise even myself. That's 9 watts more than same test/venue (albeit on a cold day) on 8 Aug 2006. I was a few kg lighter back then though. For reference, my best power on that course is 328W (and at a lighter body mass as well).

I followed that up with the MAP test on Friday, riding Thunderbird 7 (my indoor trainer bike). Here's the graph:



My MAP was 385 watts (mean maximal 1-minute power during the test). Yikes! That's up 30W (8.5%) on my last MAP test on 25 September.

What's even scarier is that's only 14W shy of my best ever MAP of 399W (as measured by Powertap on a Computrainer). Allowing for some drivetrain power losses for recording with Powertap vs SRM, that still means my MAP has attained nearly 95% of pre-accident levels. That is pretty remarkable under the circumstances. It's only six months since I put the bike into a home trainer and tried to pedal.

What about my sprints?

Well for a couple of Sundays now I have gone to my local track for some sprint work. I am now getting peak power > 1200W on several occasions. Pre-accident, I would regularly be ~ 1350W and occasionally up to 1400W. So sprint power is not too bad either.

So my body is indeed a Swiss Watch. It seems that coach has worked out how to wind it quite nicely!

Of course one of the consequences of that testing is my estimated Functional Threshold Power has gone up from 240W to 275W. Since my daily training stress is calculated relative to FTP, it means that rides have to be at a higher power now to earn the same Training Stress Score.

As they say, it doesn't get easier, you just go faster.

This morning I woke late, and then checked what was on the program today. 2.5hrs, that's what! Holy smoke! OK, so I saddle up, head out the front door and get into it doing a run to Kurnell, being my first proper solo run back out there in the world of Sydney's roads.

A little over 2.5 hours ride time later I get home, with two short stops along the way to remove, dry and replace my leg liner which seems to accumulate the contents of Sydney Harbour while I'm riding.

Average Power: 186W
Normalised Power: 198W
TSS: 130
Distance: 71.4 km

Ironically, I came home via "that gate". It was definitely open when I rode through.

One last thing - I have chatted to my prosthetics specialist George and we will hook up again in the new year to start looking at the design and construction of a leg dedicated to cycling. Picking the right time for that is tricky, as since I am now trimming down, that affects the fit of my stump in the socket. So getting the leg too early might reduce its useful life.

I did however use some of the funds raised to purchase a new leg liner (or as Paul Craft calls it, the big blue condom that goes over my leg) and distal cup (the current cup is looking a bit worse for wear). That was $1300, so the benefit funds are already being put to good effect. I'll now be able to rotate the liners and hopefully get a bit more useful life out of them. Early in the New Year, I'll probably add a third liner to the stable.

So there you have the latest. All going well as far as training goes. More hard work ahead of me though, and probably a few races over the next month.

Thank you

OK, it's the morning after my benefit - which was a really fun night of racing and a humbling experience as a I watched people open their wallets to bid for the items generously donated for auction.

Something between $5000-$6000 was raised (after venue hire expenses were paid), which was really amazing. I won't know the exact amount until all the various remnants of bid money and entry fees appear.

There was also the small matter of my 500m time trial to see how much I could improve on the time I set back in August.

My time:
28-Nov-08: 41.9 seconds
08-Aug-08: 46.5 seconds

an improvement of 4.6 seconds in 3.5 months. :D

Power peaked at 1122 watts, with a 10-sec power of 1063 watts.

Cadence reached 122 rpm, which on the 50x15 (90") gear equates to a top speed ~ 51kph. (I didn't have a wheel speed sensor operating).

Earlier in warm up I did a test 1/2 lap fly and managed a top speed ~ 58kph (141 rpm in 49x15 (88") gear).

As PeterB said, OK, now to break 40. Thanks Pete LOL

When I get some pictures, I'll be sure to post a few up.


The money will all go to helping me fund prosthetic equipment dedicated for cycling. Once I have final details of monies I'll post on the blog and keep a running tally of where it goes. I'm not sure how long before I actually get a dedicated leg made up. Once my prosthetics specialist is happy that my hip has sufficient strength to re-align the leg (currently my "foot" is laterally offset by ~ 25mm), then that'll be the time to do it. All I can really say is it'll be sometime in 2009 I expect. In the meantime, I have other less sexy but essential items like leg liners and socks to purchase so I can continue to enjoy training and competition.


Once again a huge thanks to everyone involved in putting it all together:

- the volunteers on the night (Fred & Helen Vella, Chris Greaves our video man, Mike O'Reilly, Peter McCrystal, Samantha Kosky and others judging and organising - how does one get all the names!!, Ray on first aid, the triple-bunger photography team of Ernie Smith, David Lane and Chris Belyea, Sean Eadie on the derny, UCI Commissaire Peter Tomlinson, and Rik Fulcher who teamed with Paul Craft for the best commentary and auctioneers team one could hope for)

- the staff and management of Dunc Gray Velodrome and Bankstown Sports Club/Handlebar Tavern for the venues and catering

- Cycling Australia and Cycling NSW for their support

- the very generous sponsors who donated some tremendous prizes ranging from wine, to books, software, two sets of wheels, a day's hire of DGV with coaching by Gary Sutton, signed jerseys especially for the occasion from Stuart O'Grady, Anna Meares and Sean Eadie amongst lots of other items

- all the riders who I'm sure had a blast

CTL = Fitness

Oops.

It's been a little while since last post. Forgive me, busy days lately.

So a quick update. My training continues and my leg is holding up OK. A little while back I talked about the "Thin Blue Line". Here is the lastest version:


As you can see, the blue line continue to move onwards and upwards at a steady rate. To keep that line rising, you have to train a bit more and/or a bit harder than you did the previous week. It's relentless like that. Back off the effort and the blue line starts heading south again.

Training now comprises a variety of workouts including basic core endurance work, some focussed tempo and time trial pace efforts, and some lactate tolerance work thrown into the mix to give me a bit of a boost for when I attempt that 500m TT in a couple of weeks from now. I am riding 5-days a week now and doing the occasional race.

Last weekend I raced a local criterium at Heffron Park. I rolled over the line for 3rd, although my attempt to sprint for a win never eventuated as a couple of guys next to me crashed and so I pulled out of the effort to ensure they were the only ones to hit the deck. What my training has lacked has been some time at the track to do some sprint and start practice. Getting time for the track has been a bit tricky lately. I'll need a couple of sessions before doing my TT.

So, back to the blue line (Chronic Training Load). As shown in the chart above, my CTL has now reached the 50 TSS/day mark. And today marks exactly 5-months since I first put my bike on a trainer and tentatively pedalled for 15-minutes. So it's not a stellar ramp rate in training load (roughly 2 to 2.5 points/week) by any measure but being a CTL "hare" is not smart training anyway. It is a prudent and manageable increase in the training workload.

One of the "old" power training sayings is:

CTL = Fitness

Well it's a pretty broad statement but I thought I'd give an example of what it means.

Under the chart above (the one with the blue line) is another chart covering the same time period. This one shows my best 60-min power in each 4-week block. The orange and blue columns show my best 60-min power expressed as Normalised Power and Average Power respectively. As you can see, as the CTL blue line rises, so has my 1-hour power.

Simple really. Train more, get fitter. It will keep doing that for some time. Until it doesn't of course! But that's another story.

My cycling leg

This post is especially for Jason and anyone else that's interesting the the specific set up I have for cycling.

Jason commented on my previous post about his desire to tackle the Alpine challenge. Jason is a below the knee amputee as well.

The Alpine - that's awesome!! No way I could imagine doing that at this stage. I wrote about coaching a rider who did the Alpine a couple of years ago in these two posts.

You go Jason!

So, in summary, have a look at these posts which show my cycling leg set up in a little more detail:

My new leg and socket design

How my cycling leg attachment works

The cycling cleat attachment and adapter plate

The urethane adapter to provide lateral roll for out of saddle efforts

My prosthetics guy made my everyday walking leg socket with quite a shallow rear cut away with cycling in mind. The rear of the socket is such that I am able to pedal with a full length crank.

But remember I have the cleat directly at end of the pylon and so the knee doesn't need to bend quite as much as if the cleat was positioned further forward simulating an "under the ball of foot" position.

The socket also has some funky design at the front.

The other adaptation I haven't shown in pics is some soft foam-like material I place at the front of the stump below the knee, in-between the sock and liner, so that it fills the gap between the stump and top front of the socket when you are pedalling. Bend your knee when sitting and you can put your hand/fingers into the largish gap that forms betwen the stump and socket.

The gap isn't there when standing up of course but with the knee constantly bent on the bike, I found filling that gap really helped with power production and provides a much more secure feeling. I just got some off-cuts from a Clark Rubber store.

As my prosthetics guy says, the aim is to maximise the contact surface area between stump and socket. That will be something we look at when designing a dedicated bike leg socket.

Eventually I intend to have a dedicated socket / cycling leg made, however before that happens I need to further strengthen my hip so that the lateral offset of my "foot" can be brought a little more in line with the hip and knee.

For a permanent cycling leg, I envisage something like what Jody Cundy of Team GB paracycling squad had made. Anyone who can do a 65 second kilo sure has a leg that works!



See this item for more details:

Jody Cundy Interview

In there you'll see his new (the carbon leg) and old leg set ups. I don't expect to have my cleat positioned as far forward as Jody has his - he simply replicated what he was used to with his prior set up when wearing a cycling shoe over a prosthetic foot.

The one thing you have to consider with a direct cleat to pylon arrangement is that you can't walk on it. So logistics becomes a factor when planning on going for a ride.

Another thing I've noticed, since I have more than one bike, is that I am now much more sensitive to the different Q-factors of the cranks on my bikes - to the extent that I need to alter the angle of the prosthetic cleat attachment in order to ride a bike with different cranks. My two road bikes have 175 mm Campagnolo cranks however one is a Record crankset and the other a Chorus model and they have different Q-factors.

I never realised until now how much the ankles do the job for us, managing all the lateral roll when out of the saddle and coping with the small differences in positional set up.

What did Joni Mitchell say to us in that Big Yellow Taxi song?
Don't it always seem to go
That you dont know what you've got
Till its gone....

No parking lots here though!

3rd in line

I've been a bit busy of late, so my posting rate has slowed somewhat.

I was supporting some clients and buddies at the World Masters Track Cycling Championships last week as well as doing some other stuff. I'll write a bit more about that another day (it was a very successful championships for my club, my buddies and clients). Despite the "busy-ness", my training continues and so today I took myself down to Heffron Park for a criterium race.

Signed up for D-grade and it seems there were enough for a separate D-grade bunch today. Not sure how many we started with, maybe 12-15 riders. A moderate North Easterly wind kept the pace down on the back half of the circuit. It was a nice afternoon (race starts at 5pm), sunny and ~ 23 C.

Race is 14 laps of Heffron's 2.04km circuit.

Something new today - I bought a new leg liner during the week - that's the compression liner that goes over my stump and has the metal pin at the base that secures my stump into the socket. My existing one is tatty, worn and with holes appearing and getting bigger. So I swapped the pin over to the new liner and wore it in the race today. It would seem that cycling is quite tough on the liners.

One liner @ $1000 thank you very much. Ouch! So my first one only lasted a handful of months. It would seem the strategy is to have multiple liners, so that you can rotate them and allow each one a chance to recover properly before using it again. It looks as though I better save a few more pennies and get some more liners. That also means some getting extra pins sorted as well.

We keep learning....

So with the new leg liner on and a 20-min warm up on the circuit out of the way, I head to the start line and off we go for a 14 lap adventure.

I finished 3rd. Didn't want to leave you in suspense now, did I :)

Not entirely sure what to expect of myself, basically I was just there to see how I would fare. Pace was fairly steady, which was fine by me. A few surges by some enthusiastic souls who seemed to like riding into the wind. That was OK and at one point a lone rider put on an effort down the main straight. Seeing that nobody was going to go pull them back, I decided to try myself and it wasn't that hard to close the gap. They didn't last long anyway and soon we were together again.

So I just kept my nose out of the wind, noggin side up and never really had to work all that hard. Indeed at times I was just seeing how much soft pedalling/coasting I could do at various times, practicing basic race skills.

I unintentionally unclipped my prosthetic leg from the pedal a couple of times and I'm not entirely sure why, so I'll need to look into that. Since the pace wasn't on, it never really was a problem - I was able to calmly clip back in, but in a harder race it sure wouldn't help matters.

There weren't many left by the end, maybe a half dozen.

Stats:
Duration: 50:19
TSS: 83.7 (intensity factor 0.999)
Average / Norm Power: 220 watts / 240 watts
Distance: 28.566 km
Cadence (max/avg): 109 / 86 rpm
Speed (max/avg): 50.5 / 34.0 kph


So given I didn't rate that as a super hard race and I had an IF of 0.999 for 50 minutes, then it would suggest my fitness is going along OK.

I'll probably have another crack in a couple of weeks.

The Thin Blue Line

Time for a catch up on how my own training is going.

A couple of weeks ago I mentioned the results of my performance tests, namely a time trial level effort, a MAP test and some sprint efforts. Results were:

Time Trial power (20-minutes): 252 watts
Maximal Aerobic Power: 355 watts
Neuromuscular Power: 1074 watts (5-second max average with a peak of 1109 watts)

Estimated Functional Threshold Power: 240 watts.

So with those results locked away, training has been continuing. One thing to notice is the ratio of TT power to MAP. In my case, my TT power is a relatively low percentage of MAP (or if you like, my MAP is a relatively high percentage of TT power).

Hence my maximal aerobic abilities are really not a limiter (at this stage) to the ongoing development of my TT power. This helps to determine what my training focus should be for this next phase of training.

As with most cycling (except for track sprint/BMX), the focus is almost always on increasing your TT power, since it's the most import physiological marker of performance potential.

Of course rolling around the track is fun and so I will keep doing that. It also provides a safe environment for maximal sprint type efforts. Training should be hard work but it also needs to be enjoyable (mostly) otherwise we lose motivation.

So, my training will continue to be focussed on improving my sustainable TT power. Core endurance, tempo and threshold level efforts are now staples in the aerobic development diet. I'm also going to throw in a local criterium race or two as a challenge (and it's good training anyway).

My training workload is gradually increasing each week, and as I train my body is adapting to the new stress levels and responds by allowing me to continue to increase the workload. This ability to manage a continually increased workload is shown by the steady rise in the blue line in the chart below (the blue line depicts my Chronic Training Load (CTL) since I first hopped on the trainer just on four months ago).

The rate at which that blue line can rise is typically limited to a maximum of 5-8 TSS/week. Going above that rate for any length of time is usually met with an increased susceptibility for illness and possibly leads to a degrading of performance. In the opening block, I was increasing CTL at ~ 4 TSS/week and following a break from training I have been increasing at ~ 2 TSS/week. Due to the recovery from injury, it pays to be a little conservative in the rate at which CTL lifts.

Of course, for the blue line to provide such good indicator of changes in workload levels, it requires one to have an accurate understanding of their current fitness level. Hence the testing a couple of weeks ago. Not only does it set a benchmark for fitness, and provide solid data from which to determine what elements of my physiological profile need the most attention, but it also provides a sound basis on which to determine the appropriate workload and the rate at which it should be increased.

There is a period where the blue line heads south. I was having some trouble with my stump - it wasn't coping well with the stresses inside the socket and became quite sore. I thought it would need a couple of days rest but it turned out to need a lot more than that. Hence almost no training for a week and a half. It turned out that it was a technical problem that I managed to solve and so once the soreness faded, I was able to start training again and arrest that downward decline.

So far so good for the "thin blue line".

Benefit is On!!

OK, Paul Craft has waved his magic wand and it's all systems go for my benefit night.

Date has been re-set for the evening of Friday 28 November 2008.

Yippee!!

There should be some cracking racing, with the 3-person team format (a Sprinter, an Enduro and a Women making up each team) and teams can be club or trade-team based. It will be fast and furious fun, so if you're not racing, it will certainly be entertaining to come and watch.

Details of the racing and function are listed on Crafty's RAW Track website here:
Alex Simmons' Benefit Night

The event is now on the CNSW calendar and can be seen here:
CNSW Race Calendar - Alex Simmons Benefit

Entries via the CNSW web site.

Towards the end of the racing, I get to do another 500m TT and see how much I can beat the time I set back in August.

Once again a huge thank you to Paul Craft for putting it all together and for everyone that's helping out and/or contributing to the auction pool for the evening. There are some smashing items up for grabs.

Hope to see you there!

Benefit Postponed

My benefit race and function, originally organised for Saturday 1 November, has been postponed by a few weeks due to a clash of dates on the CNSW track calendar. A last minute change by the Wagga Club and CNSW sees their Cat 1 race carnival being re-scheduled to that day and so to avoid a clash Paul Craft has been asked to find an alternative date for my benefit.

I know a new date was chosen and appeared to fit in OK but I can't confirm that just yet - Paul is organising it all. It will likely be a Friday night event now, instead of a Saturday afternoon as there are now no free Saturdays on the summer calendar left.

Look out for more details directly from Paul.

I'll post an update once I have confirmed details.

MAPpity doo dah, MAPpity day

I did my final of three power tests today to determine my Maximal Aerobic Power (MAP). If you want to know a bit more about what that is, just click the link.

Before we get to the result of my test, a little background Chronology:

11 Apr 07: My accident, admission to hospital emergency and multiple operations ensued.

16 May 07: Left below knee amputation.

15 Aug 07: Discharged from hospital

24 Oct 07: Collect interim prosthetic leg, begin to learn to walk again

04 Jun 08: Collect new prosthetic leg. Start to stand and walk again with comfort.

13 Jun 08: first ride on indoor trainer since accident. 15-min at 100 watts and using special short 100mm left crank arm (as my knee wouldn't bend sufficiently for a normal crank) and a flat bed pedal to rest my shoe and "foot" on.

28 Jun 08: first ride on special indoor ergo bike.

29 Jun 08: MAP Test - 246 watts

31 Jun 08: first ride using special prosthetic cycling leg attachment

11 Jul 08: first ride outdoors at Centennial Park for 45-minutes - now using a 155mm left crank

19 Jul 08: first race

21 Jul 08: now using a 165mm long left crank

22 Jul 08: MAP Test - 289 watts

26 Jul 08: second race

01 Aug 08: first ride on track

08 Aug 08: 500 metre time trial at Dunc Gray Velodrome

12 Aug 08: Some problems with stump - experiencing some pain and skin integrity issues. 10 days break from riding while I sorted this out.

13 Sep 08: now using full length cranks on all bikes (165mm on track bike, 170mm on ergo bike, 175 mm on road bikes)

21 Sep 08: trial use of poly urethane bushing under cycling cleat to aid out-of-the-saddle sprinting control

23 Sep 08: Time Trial test - 20-minute power 252 watts

25 Sep 08: MAP Test - 355 watts


What can I say, other than I am personally a little amazed. My previous best able-bodied MAP test result was 399 watts. So today I hit 89% of that. It's only 6 watts less than my MAP test from August 2006!

OK, if we want to get technical, the MAP tests this time were measured with an SRM power meter, which given it's a crank based power meter, will give ~ 2% higher reading than my Powertap, which is what my previous MAP tests were measured with (since the Powertap is a hub-based meter and drivetrain power losses are typically ~ 2%).

And for the technically minded of you, yes the SRM is calibrated and zero offsets checked and stable.

Even still, I consider it a pretty amazing result so early in my comeback.

So much more work to do.....

Testing Times #2

In November 2006 in this post I wrote about one method used for testing my current level of aerobic fitness - the time trial power test. It is a test to see how hard you can ride for a given distance. As a test for fitness, it's not the time taken for the course that matters so much as the average power you can sustain during the effort.

Time taken to complete the course isn't a great indicator of changes in fitness, since time can be readily affected by conditions on the day (wind conditions as an example). But power is power, provided you are conducting the test in a reasonably similar environment (altitude, terrain and it's not hideously hot or cold). It also helps to make sure you are not overly fatigued on the day of the test.

The length of the test is typically 10-miles or 16-kilometres. Doesn't need to be exact as it's power we are interested in, not the precise distance or time taken. Of course, if you ride 10-mile TTs regularly, then they are perfect opportunities to use as tests.

Today I was scheduled to do my first such test since returning to the bike.

So what happened?

Well of course today it decided to be a stormy rainy yukky sorta day, didn't it. And right now I don't need the hassle or riding in the rain.

So that left me with the other alternative - to get on the ergo bike and go for it. So that's what I did. Only trick is I have no speed/distance data on the indoor ergo bike, so I opted for a 25-minute long test.

Unsure of how hard to start with, I decided on starting at 220+ watts and then to go by feel from there. Here is the power chart from my effort (yellow = power, green = cadence):


Overall, for the 25 minutes I had an average power of 248 watts and a peak 20-minute average power of 252 watts.

So that's not too bad all things considered.

Testing continues later in week, with a Maximal Aerobic Power test.

Kilo What?

Training is going well. I'm back on a program and so far so good. Yesterday was a solid but not super hard roll in the park - an hour at 200 watts, which clearly means my Functional Threshold Power (FTP) is now higher than 200 watts!

I'll have a better idea of that this coming week as I am scheduled to do a 16km time trial test run and also a Maximal Aerobic Power (MAP) test. That should be fun!

Today I ventured back out to the Dunc Gray Velodrome. This was the first chance I've had to test out my experimental "bushing" for my cycling cleat. I had previously mentioned how I found the bike behaves a bit strangely when doing out of the saddle accelerations, as there was no lateral ankle roll anymore on the left side since there is no ankle, just a straight pylon attached to the cleat and pedal.

So I thought about what I could do and had a few ideas but first I wanted to test the theory to see if some polyurethane under the cleat would do the trick by allowing a bit of sideways flexion.

So while looking for suppliers of polyurethane I also decided to have a closer look at one of my other ideas - to use something like a skateboard truck, which I thought would replicate the ankle flexion quite nicely. So off I go the skateboard shop to have a look...

While there and looking at the trucks on display, I told the shop assistant what I was trying to do and had brought my cycling leg attachment with me. He said, hang on - I might have something for you - and showed me this (the black thing with the H cut out of it):


It is a polyurethane spacer which goes between the skateboard truck and the board - used to provide a little vibration damping and protection for the wooden board from the metal truck. It looked about the right size and hardness, so I took a couple with me to try it out. It has a nice flex to it:


I drilled extra holes and then simply placed it between the cleat and the metal adapter plate, like so:

Not worried about cutting it down to size at this stage (since I didn't know if it was going to work or not) I decided to give it a go and see what would happen. Well today I rode it at the track and after about 30-minutes of rolling around, I decided to do some standing starts.

It worked really well. Once up to speed, the bike was giving me the ability to rock it side to side in a more natural manner without the sensation that I might pull my "foot" out of the pedal.

So after a few of those, I started to get adventurous and rolled around mid track, waiting for some others doing acceleration/speed work. As they passed under me I would get out of the saddle and accelerate down the banking, chase and pass them on the finish line if I could (which I did).

So finally, I decided it was time to get right up the banking and do a sprint effort a la the ubiquitous 200 metre flying time trial. So I rolled around the top and gave it a crack, doing a 3/4 lap effort. I had to sit in saddle a bit earlier than I would normally like but that was OK.

I hit a top speed of 55 kph. OK, so it's not that fast but 55 is OK for now (I was using an 80" gear (49x16) for those that like to know those things and had a max cadence of 142 rpm).

One other thing. On my second standing start of the day, I noticed I had a peak power of 980 watts, so I thought, hmmm, what chance of cracking the kilowatt mark today? So on my third effort I gave it a go.

1053W (5-sec MMP 1020W). :D

Mission accomplished.

Benefit

Today's post isn't written by me. It's a copy of an email sent out by Paul Craft, promoter of the Friday night RAW Track Racing Series and all round cool dude.

What else can you say about the sport of track cycling when this is what they do for you?

Well the least I could do is provide a link and show the RAW logo!!



Dear Club members.

Could you please include the following letter as correspondence at your next committee meeting.
Cheers Paul

Dear CNSW club

I am inviting your club to participate in the Alex Simmons benefit night on the 1st of November 2008, to be held at the DGV with a post race function being held in the HBT, including an auction of cycling memorabilia and other goods. The plan is to raise enough money to purchase Alex a purpose built cycling leg attachment (est. value $5,500).

Specifically, I am asking your club to enter a three person team consisting of 1 x Women, 1 x Sprinter and 1 x Track endurance rider to compete in a short but jam packed 1 ½ hour race program. Team entry is $100 and all proceeds go towards purchasing Alex a cycling leg.

Information About Alex Pre accident:

Alex Simmons is an accomplished cyclist from BiciSport club. In the summer of 2006/7 Alex won silver at the Australian Masters Points Race (MAS2) and consequently earned the right to wear the Australian skin suit at the pending World Master Championships to be held in October of that year. Other than his accomplishments on the bike Alex had also become a coach of many of Sydney’s aspiring cyclists as well as a number of Master riders. He also became a CNSW commissarie and was regularly seen at open events he wasn’t competing in. Added to all this he is also a cycling columnist for Velosport Magazine as well as his very popular Cycling Blog which takes a big interest in Sport Science.


The Accident:

11th April 2007 - Alex was on a normal morning training ride as scheduled by his coach. As usual it was an early morning ride, out at about 5.30am. He rode south from his home out to Taren Point, a route he had ridden literally hundreds of times over the past decade. Turn around via Sylvania Waters and back over Taren Pt Bridge on the way home using the cycleway on the eastern side of the bridge. That cycleway leads you into the car park of the St George Sailing Club in Sandringham and straight onto Riverside Dr. It was 6.15am as he crossed the bridge. Coming off the cycleway Alex was greeted with a closed boom gate, he hit it flush at speed, no time for braking or avoidance manoeuvres. The left leg, just below the knee took the full force and this impact. Multiple operations and many weeks of treatment later, the complications could not be resolved, resulting in the need to amputate the now non-viable lower leg. Alex spent the next 4 months in a hospital bed.

The below quote is from Alex’s Blog dated August 2007:

“So I went from my best ever personal race result, to losing my leg in a short space of time and dreams of competing at the world champs dashed. I was really looking forward to donning the Aussie skinsuit in the points race (an honour granted due to my result at the Nationals).

Still, I look forward to getting my prosthetic, walking again, losing all this puppy fat and ultimately getting back on the bike and being as competitive as before. It will take a while though but it will happen.”

Post accident;

Alex has become an inspiration to cyclist all around the world, many of whom regularly comment on his blog site; Alex is also the regular commissaire at RAW Track. He was instrumental in organising the Women’s Master Day at the DGV recently and continues to coach a number of Athletes. He has also gotten back on the bike and recorded a 500m time on 8th of August at RAW Track and competed at Heffron Park. Alex continues to give back to the sport he loves.
