Question

A 75kg man completes a maximal Grade exercise testing, and his VO2max is 3.0 L/min. (1.5 pts) This equals kcal/min. This equals ml/kg/min. - This equals _ _Mets. At what exercise intensities (=target VO2R) does he work in order to be at 60% and 80% VOR?

Answer 1

1 liter of oxygen consumed per minute is equal to 5 kcal/min

VO2 max = 3 L/min

= 15 kcal/min

= 3000/75 = 40 ml/kg/min

1 MET = 3.5 ml/kg/min

= 40 / 3.5 = 11.43 MET

VO2 rest = 3.5 ml/kg/min

VO2 max = 40 ml/kg/min

[(VO2 max - VO2 rest ) * 0.6 ] + VO2 rest

[(40 - 3.5)* 0.6] + 3.5

= 25.4

[(40 - 3.5 ) * 0.8] + 3.5

= 32.7

Target VO2 R = 25.4 to 32.7 ml/kg/min
