Rely too much on the aerobic processes (higher efficiency
= lower power output) then the athlete's speed, power and agility will suffer; all the qualities that are required to optimally perform the skill of their sport.
Power = Torque * RPM, so low torque at high RPMs can give the same power output as high torque at low
Power = Torque * RPM, so
low torque at high RPMs can give the same
power output as high torque at low
power output as high torque at
low RPMs.
