Was i mistaken or did Tony Martin win in around 20mins?
Yes, and we can show a 1000m time trial usually completed in around 60-62 seconds is 50% aerobic, so I suspect that no matter what gear one uses for a 20min effort the energy supply is nearly all aerobic. Also will be at < 35% of peak power so another great example of aerobic capacity.
Any care to suggest how strength could limit this performance. I think anyone has ample strength to ride at 35% of their peak power. I have ample strength to ride at Tony Martin's time trial pace and much higher. So if strength is not limiting me from holding his pace what is?
WRT Sprinters using weights. Did you find them mention why they perform weights. Only thing I found was Hoy suggesting their application in the first 2-3 pedal strokes of a hard acceleration. Then as power drops well below the maximum, look at the drop off in a 30sec Wingate test, or the comparison I made between a my 60sec power and the data I have from a ex World Champion cyclists 60sec power and the drop off is similar, and after 2-3 sec energy supply is no longer from stored ATP in the muscle and one then once one has burnt through the stored Creatine Phosphate in the muscle it's down to the anaerobic energy supply for 10-30 seconds tops before you start needing aerobic energy supply.
So if those sprinters understand, and it appears that Hoy does, why they lift weights then it's only to target a very small part of their performance. The majority will do too much in the gym and for the reasons that starting strength is quite important in the Team Sprint, Keirin, 500m TT and some aspects of the Match Sprint. The majority will train because they are under the illusion, as were the Aussie sprinters in Beijing, that peak strength is the main factor in sprinting.
But cycling, even sprinting is not about peak strength in the same way it is for Olympic Weightlifting, Gymnastics, Field events. When Charlie Walsh headed the AIS Track Team he trained the sprinters to run even 100m splits. In essence pacing over a 10sec effort. Reflecting the fact that you can't sustain. 100% for 10sec in cycling let alone longer durations.
At NZ Champs my rider in the 500m TT went through the first lap in 5th place but because he had paced his effort he maintained power through the 2nd to win by .5 of a second and break the NZ record. In the pursuit he was in 8th place through the 1st 1000m and 4 sec off the leader but by maintaining his pace he ended up qualifying 1st, 4 sec up on 2nd place. Also mention this rider has never seen the inside of a gym.
So in my experience (having actually coached some pretty handy sprinters) and backed up by the research I believe that a lot of sprint cyclists are spending way too long in the gym when they should be targeting the energy systems relevant to their event. The same applies to any cyclists who wishes to perform. Train the energy systems you use in racing, in the position and environment you wish to perform in.
