Question

What is the total energy expenditure for a 70-kg man doing an exercise session composed of 5 min of warm-up at 2.0 metabolic equivalents (met), 20 min of treadmill running at 9 met, 20 min of leg cycling at 8 met, and a 5 min cool-down at 2.5 met?

Answer 1

To calculate the total calories burned during the entire course, we should be reminded that 1 met is equal to 1 kcal / kg / hour. In this case, we can already perform the necessary calculations:

E = 70 kg( 2 kcal / kg / hour * 5/60 hr + 9 kcal / kg / hour * 20/60 hr + 8 kcal / kg / hour * 20/60 hr + 2.5 kcal / kg / hour * 5/60 hr) = 422.92 kcal
