I am sure Carleton will have a lot of insight into my question- hopefully some others with power data experience will join in!
recently there has been some discussion here about power data for sprinters (lets say from a flying 200m- just to keep things simple) and talk of the need for hi rates of data sampling to analyze peaks in power, speed and cadence, no matter how brief they were.
I have been operating under the thought that the short duration max-wattage numbers were good for making your roadie buddies jaws drop at coffee after a road ride with a bunch sprint- but not really the end-all in sprint analysis.
last Sunday i rode a PR flying 200m, it was my first 200 with a power meter. I was pretty excited to check the file. when i looked at it my first instinct was to look at peak power.. it was good for me, but not the highest i have seen this year, or even in the last 6 weeks. next i isolated the 12" that ends at the end of the effort- so roughly the timed section of the effort... once again- nowhere near my best 12" effort- not even the best 12" wattage of the day (i match sprinted later)
in some ways this left me thinking- wow i could of gone faster! cadence was about where i like it, so maybe a bigger gear would be faster?
then i started thinking about the effort and went back and isolated the entire effort. A 200m on ADT is a little different from some tracks since you have to maintain a higher speed early so you don't slide off, but there was a clear point on the data where things got serious. isolating from there to the end of the effort was approximately 25" effort. At ADT that is likely from mid turn 1/2 after you see "2 to go".. about the last 11/4 laps.
all wattage numbers from 15" to 25" were PR numbers for the year...
my take on this effort is: my limiting factor was obviously my 25" power, since i did not hit maximum wattage in 1"/5"/10" metrics...
this leaves me to believe that improving 30" power will improve my 200m
obviously bringing up the shorter duration numbers will help as well...
anyone have a take on this logic?
can anyone educate me as to why the shorter duration numbers and the higher rate of sample to analyze these numbers is so popular among sprinters?
