Power play

Got the Powertap setup and working this evening. Had a quick play on the turbo for a few minutes and the numbers coming back indicate that the Tacx is not as optimistic as perhaps thought. Tapping out a cadence of 85-95 the Powertap and Tacx were very similar. I hasten to add that the Tacx had not warmed up and had not been recalibrated since the last time I used it.

Far more encouraging than the Tacx accuracy was how I felt pumping out 292w (The sustained power output required to climb AdH in the hour). I'm not saying it was easy but maintaining it for 1 hour is a distinct possibility rather than an absolute impossibility. Of course, I'm assuming the PT is relatively accurate!

Lots of long rides this weekend so expect to see reams of boring data over the coming days...

W'bal its implementation and optimisation

So, the implementation of W'bal in GoldenCheetah has been a bit of a challenge.

The Science I wanted to explain what we've done and how it works in this blog post, but realised that first I need to explain the science behind W'bal, W' and CP.

W' and CP How hard can you go, in watts, for half an hour is going to be very different to how hard you can go for say, 20 seconds. And then thinking about how hard you can go for a very long time will be different again. But when it comes to reviewing and tracking changes in your performance and planning future workouts you quickly realise how useful it is to have a good understanding of your own limits.

In 1965 two scientists Monod and Scherrer presented a ‘Critical Power Model’ where the Critical Power of a muscle is defined as ‘the maximum rate of work that it can keep up for a very long time without fatigue’. They also proposed an ‘energy store’ (later to be termed W’, pronounced double-ewe-prime) that represented a finit…

Polarized Training a Dialectic

Below, in the spirit of the great continental philosophers, is a dialectic that attempts to synthesize the typical arguments that arise when debating a polarized training approach.

It is not intended to serve as an introduction to Polarized training, there are many of those in-print and online. I think that Joe Friel's blog post is a good intro for us amateurs.

For Synthesis Against A Elite athletes have been shown in a number of studies to train in a polarized manner [1][2][3] There is more than one way to skin a cat. Elite athletes adopt plans that include high-volumes of low intensity and low-volumes of high-intensity. Elite athletes have also been shown to train in a pyramidical manner
[13] B Polarized Zones are between LT1/VT1 and LT2/VT2 [1]
LT1/VT1 and LT2/VT2 can be identified using a number of field based approaches [4][5][6][7]

You can follow guidelines on mapping LT1/LT2 to cycling power to make it useful for amateur cyclists. Polarized zones are har…

W'bal optimisation by a mathematician !

So the integral computation for W'bal was expensive.

I tried to optimise from a domain and  programming perspective, where Dave Waterworth, a mathematician found a much more elegant and fast reformulation.

This means W'bal can EASILY be computed as you ride.

To explain the math here are his words;

I posted a comment on you Blog post on optimising the Wbal model. I've done some more thinking and I defn think it can be done without visiting the previous samples as the Skiba formula can be decomposed further, i.e. From your blog I believe the integral part of the equation is:





Basically this takes a weighted sum of preceding W'exp samples where the weight decays at a rate determined by tau, older samples are weighted less than newer ones. We can approximate as a sum provided tau is large compared to Ts (the sample rate):





Basic properties of exponential functions allow the for…
