What are metabolic units?
Definition
Absolute vs. Relative VO2 units; Absolute units – independent of body weight; liters of O2 per minute (l.min-1); Relative units – dependent on body weight; milliliters of O2 per kg per minute (ml.kg-1.min-1); Good for comparing VO2 between subjects of differing body weights; Be able to convert between absolute and relative!
Term
If two people have the same absolute VO2, who has greater relative VO2?
Definition
If a 50 kg person and a 70 kg person have the same absolute VO2 (2 L/min): 2 L/min = 2000 ml/min; 2000 ml/min ÷ 50 kg = 40 ml/kg/min; 2000 ml/min ÷ 70 kg = 28.6 ml/kg/min.
