The harder a person works, the more energy is expended and the more oxygen consumed. The metabolic intensity of an activity may be expressed in terms of oxygen uptake or METs (metabolic equivalents).
1 MET = 3.5 mL oxygen per kg per minute = oxygen uptake at rest
oxygen uptake in mL per kg per minute =
= (oxygen uptake in mL per min) / (kilograms body weight)
• Use of fat free body mass may be preferable to total body weight since the latter may fluctuate with the amount of fat present (page 271).
