velomanct said:I agree that there could certainly be an error with Papp's peak power being close to 2000. I have ridden with him a few times and he is relatively small (big legs though!) compared to most any other sprinter.
How can 20 second power not be important for the 200 meter time trial???
They need to accelerate up to ~43mph and then maintain that speed for the next 10 seconds. take a look at the power profile of a 200 meter time trial, and you will see that it is MUCH more than a 10 second effort. It takes at least 10 seconds to go from ~25 to the 40mph range. I am surprise you are unaware of this acceleration period.About that 5 second column. If the top is 24w/kg and Nothstein (Sydney gold condition) was 98kg, that would mean his 5 second power is 2350watts. His absolute peak (1 second) would have to be around 2600watts.
(my 1 second peak is 200watts above my 5 second power)How come we NEVER heard of ANY match sprinter capable of hitting 2600watts? In the cyclingnews.com interview with Nothstein 4 years ago, he stated he was rated at 2200watts.
What gives?
A match sprinter undertaking a 200m TT would not be on maximum power before the start of a 200m. He/she has to apply maximum power to hit top speed somewhere in the back straight (250m track) and try and hold it (max around 6 seconds). Attempting to be on max speed on or near the start of the 200m is a recipe to be legless and rapidly dropping speed over the last 50m.
You have to be as economic as possible yet fast before entry into the 200m timing zone.
Therefore I don't think 20 second power is relevant to a 200m TT.
My experience and my observations of others about peak power (5 second or 1 second) is that once the spike is achieved there is a rapid decline in power. It is easy to spike for one second in a lab but not in the real world of track racing.
Try a few 200m TT's on a banked velodrome in training and through trial and error you will start establishing optimum jump power and speed in your approach to ride the most efficient 200m TT. You will quickly learn it ain't max power and speed before the 200m.
