Martin JC, Gardner AS, Barras M, Martin DT. Modeling sprint cycling using field-derived parameters and forward integration. Med Sci Sports Exerc (in press).

(Note for Fergie: this rider's peak power was "only" ~22 W/kg.)


I could only read the abstract but where does it say the kilo rider went all out and aimed at the highest possible speed instead of accelerating up to what was almost his maximum possible speed? This would be simple to measure.

We can see in the times of the top few riders that some are better in the first lap than others, while a few are slower at the beginning can be faster in the third lap and win the race. Whether their slower start is intentional or not, the winner isn't always the guy with the lowest first lap time.

Interesting that the pursuiter went all out for about 12 seconds then backed off. I've heard some people say you shouldn't go all out right from the start of a pursuit because the start isn't that important compared to the possible penalty to be paid later.

And of course, people who do not spend their life training for the kilo sometimes find that a pacing strategy that works best for them (lowest time for the event) will not be one that aims at their highest possible speed at the start.

In the paper.

It was (albeit not necessarily the way you think).

They didn't (actually, a better way of putting it is, they might have).

As you might expect, the paper doesn't say - for each of the three subjects it just gives a few physical characteristics, shows a sample power file during their respective events (i.e., kilo, flying 200 m, 500 m), and states that they all are or were World Champions in sprint (i.e., non-endurance) track cycling.

Trying to sit back and hold my tounge but as you know there comes a point that I cant Why cant someone post a file that shows a 10.5 200 and the guys height and weight. Then do the same for a Kilo....maybe a 105 or so...No names ,no dates, no pics just a file. The only one I have seen is the sample on the SRM website. Ok I am going back to my corner

Well I would, but I'm not sure that it would be ethical of me to do so. MSSE now owns the copyright to the paper, and while posting it after it is published would probably fall under the "fair use" exemption, doing so before it is published seems questionable to me.

Here is a 1.04.8 Kilo from 2004 NZ Track Nationals on a 285 outdoor concrete track (poorly designed bankings).

Fergie my power off a standing start is about 150-200 less than on a jump.(I am working on it) The reason I mention that is that my sweet spot for power is about 130-140rpm. The energy required to start, seems to take power away from the peak. Your very gifted rider seems to reach 40 mph . That seems consistant with someone that went all out and held.? I havnt done ant 1 min efforts, but have done a bunch of all out 30 sec efforts off of standing starts . The power curve looks very similar to the his first 30 secs. ( I most likely out weigh the lad by at least 20 lbs though)

Experiment to see what approach works best for you. Try standing start 650-750 meters max efforts to help decide. Look at your max speeds after accelerating so you learn what yours should be for your lowest kilo time.

FWIW, it's perfectly normal for your peak power during a standing start in a typical gear to be lower than your true maximum power. Muscular fatigue occurs very rapidly, so to generate maximum power you need to be at optimum cadence after only a few seconds.

Also BTW, the fact that you make maximum power at 130-140 rpm suggests that you may be skewed a bit towards the fast twitch end of things (see more below). OTOH, somebody with a lot of slow twitch fibers (like me) will achieve maximum power at slightly lower cadence, e.g., 120 rpm.

Again, the magnitude of decline in power over 30 s suggests that you're more fast twitch than average. (I could even calculate a percentage for you from a regression equation I developed as part of my masters thesis, but it would only be an estimate since the correlation, while high, certainly isn't perfect).

All things considered, Bill, it appears that you've done the right thing by focussing on track cycling...except, of course, for the fact that you don't have one nearby!

I only have the terrain close to my house right now..... Mostly at night and cold too..... I am lucky to be on the roads at all. The other day I was sprinting and it started snowing.... You California boys and your 60 degree winter days Ill try a few things when I get to Fla in a couple of weeks; first being shorts. My best max of a standing start last year was 36mph, compared to 38.5mph off a jump. I have gotten better since then, but I have been farting around with crank lenght an gearing. Geeze I would kill for a local coach. Thanks Warren

Thank you Andy. They race on small car tracks here. That ought to be interesting .When I finally get this crank length thing sorted out and I am not working around weather, I will have my friend attatch my powertap info and everone can pick on me My numbers to date are not very noteworthy, but I am having fun, improving , and learning alot from training and from guys on this site. Thanks again
