How many kcal would a 200-kg man utilize in a minute if exercising at 4 METs?

• A. 10
• B. 12
• C. 14
• D. 16

Answer: (C)

To determine how many kilocalories a 200-kg man would utilize in a minute while exercising at 4 METs, it's important to understand what METs (Metabolic Equivalent of Task) represent. One MET is defined as the energy expenditure at rest, which is approximately 1 kcal/kg/hour. To calculate the energy expenditure at a specified MET, the formula is: Energy expenditure (kcal/min) = MET value × body weight (kg) × 3.5 / 200 For this scenario with a MET value of 4, the calculation would be: Energy expenditure = 4 METs × 200 kg × 3.5 / 200 Energy expenditure = 4 × 3.5 Energy expenditure = 14 kcal/min This shows that a 200-kg man would utilize 14 kilocalories in a minute while exercising at 4 METs, making the correct answer the one that states 14. Understanding this calculation is crucial, as it reflects how energy expenditure is directly proportional to both the exercise intensity (METs) and body weight.

To calculate the energy expenditure at a specified MET, the formula is:

For this scenario with a MET value of 4, the calculation would be:

Energy expenditure = 4 METs × 200 kg × 3.5 / 200

Energy expenditure = 4 × 3.5

Energy expenditure = 14 kcal/min

This shows that a 200-kg man would utilize 14 kilocalories in a minute while exercising at 4 METs, making the correct answer the one that states 14.
