For short
sprints, The stored muscle energy source, ATP (andosine tri-phosphate),
can supply the needed energy in an anaerobic (non-oxygen consuming) process.
As the time of pedaling increases, oxidation products (lactic acid) build up
in the muscles and fatigue starts to decrease the sustainable power. At long
times the steady state energy conversion process must become aerobic.
The
diagram shows the results of several different measurements of human
power output as a function of time. The
blue line indicates that 100 Watts is the maximum healthy person
steady state power output that can be relied upon. |
