THE ENERGY COSTS OF STRENGTH, SPEED, AND POWER
Citius, Altius, Fortius – faster, higher, stronger – the Olympic motto. These attributes make sport exciting. But from the perspective of an exercise scientist, higher exercise intensities make calorie counting frustrating as the estimation of anaerobic energy expenditure and the requirements of excess post-exercise oxygen consumption (EPOC) – also known as the afterburn -are incompletely understood.
Work within Dr. Christopher Scott’s laboratory has revealed that the majority of the energy costs of brief bouts of resistance training come from anaerobic (without oxygen) and recovery energy expenditures; this finding is of interest because the estimation of energy expenditure for lower intensity aerobic-type exercise (walking, jogging, cycling) is based entirely on exercise oxygen uptake.
Our methods are unique in that we employ 3 measures to estimate the energy costs of strength, speed and power:
1) exercise oxygen uptake,
2) blood lactate, and
3) a recovery oxygen uptake.
Most labs use only 1 or 2 measures.
