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

To determine the caloric expenditure for a 200-kg man exercising at 4 METs, it's important to understand how to apply the MET value in relation to body weight. MET, or Metabolic Equivalent of Task, represents the energy cost of physical activities in relation to resting metabolic rate.

The formula for calculating calories burned per minute based on METs is:

Calories per minute = METs × weight in kg × 3.5 / 200

In this case:

1. The weight of the individual is 200 kg.

2. The MET value is 4.

By plugging in the numbers:

Calories per minute = 4 × 200 × 3.5 / 200

Simplifying this equation:

1. Multiply the MET value by the weight: 4 × 200 = 800.

2. Now, multiply by 3.5: 800 × 3.5 = 2800.

3. Finally, divide by 200: 2800 / 200 = 14.

Therefore, the man would utilize 14 kcal in one minute while exercising at 4 METs. This outcome reflects the significant metabolic demand placed on a person of this weight while engaging in moderate-intensity activity expressed by
