Ok, so I’ve got a general understanding of the Sliding Filament Theory and the actions of ADP converting to ATP, etc. So whenever I see athletes warming up for competitions, most people are doing some sort of plyos and jumping around and whatnot while warming up for something that almost exlusively uses the ATP-PCr pathway such as a 100m or 200m run.
So in seeing the warmup and everything, I sorta wonder how much phosphocreatine is depleted during a typical warmup and how long it would typically take for those stores to be restored back to baseline, resting values? Lets say an athlete warms up and stops his warmup 5 minutes before his race actually starts - would his PCr stores be back or close to the baseline values that would be optimal for the race?
So essentially could an athlete “warmup” (have adequate blood flow to the working muscles immediately before the event starts, elevated HR, increased catecholamine response, etc) without actually going through the typical warmup of jumping around?
