Answer #1

a) The VO2 max is given as 3.5L/min which is equal to 3500mL/min. The weight of person is given as 140 pounds which is equal to approximately 63.5 kg. Hence, her VO2 max expressed in mL/kg/min is:

b) MET or Metabolic Equivalent minute denotes energy expended in one minute while sitting down at rest. 1 MET is equivalent to 3.5 mL of O2 (oxygen) per kg of body weight. Hence, 55.12 mL/min/kg of VO2 max will be equivalent to 55.12/3.5 = 15.75 METs.
