Question

1a) During the YMCA Cycle test, the predicted VO2max was calculated in mL/min. What had to be done to calculate the relative predicted VO2max?

Hint: (look at the units)

divide by weight

multiply by 1000

divide by 1000

multiply by weight

1b) During the YMCA Cycle test, the predicted VO2max was calculated in mL/min. Jill's (60kg) answer was 2773 mL/min. What is her absolute predicted VO2max?

2.8

166.38

46.22

27.7

Answer 1

Ans-1a). divide by weight

VO2 max is defined as the maximal rate at which an individual can process O2. Relative VO2 max is VO2 max relative to the body weight of the individual and therefore helps to compare the oxygen consumed and aerobic fitness in different individuals. Therefore , relative VO2 max is VO2 max per body weight. So it will be divided by body weight and then expressed as ml/ min/ kg.

Ans-1b). 2.8

Absolute VO2 max is the maximal rate of oxygen consumption. It is irrespective of the body weight and is expressed in litres per min. So here according to data converting 2773 mL / min into L/ min by dividing it by 1000 gives approx 2.8 L/min.
