SUMMARY
The discussion focuses on calculating the physical work done during a workout with a metabolic rate of 700 watts and an efficiency of 10%. The total work can be determined using the formula: total work = power × time. Given the efficiency, only 10% of the metabolic rate contributes to physical work, resulting in 70 watts being used for work over a 20-minute period, equating to 23.33 joules of physical work.
PREREQUISITES
