Question

A 56-year-old male weighing 100 kg exercised on a cycle ergometer. His O2 max was 2.8 L. How many METs of work did he perform?

Answer 1

The person performed 2.8 METs of work during the exercise.

Step-by-step explanation:

MET, which stands for metabolic equivalent, is a unit used to measure the energy expenditure during physical activity. One MET is equivalent to the amount of energy expended at rest. The MET level of an activity can be determined by dividing the rate of energy expenditure during the activity by the resting metabolic rate.

To calculate the METs of work performed, we need to know the rate of energy expenditure (O2 consumption) and the resting metabolic rate. In this case, the O2 max was given as 2.8 L. The resting metabolic rate can be estimated using a table or formula. Let's assume it is 1 MET.

To calculate the METs, we divide the rate of energy expenditure (O2 consumption) by the resting metabolic rate:

METs = O2 consumption / Resting metabolic rate = 2.8 L / 1 MET = 2.8 METs

Therefore, the person performed 2.8 METs of work during the exercise.
