Please answer all parts!

Resting VO2: 240 ml/min

VO2 at 200 watts: 3,900 ml/min

Level of exercise: (200 watts = 2.86)

a.) How many kilocalroies epr minute are expended at rest?

b.) How many total kilocalories per minute are expended during exercise?

c.) What is the expenditure that is attributed to exercise only (Exercise-Rest)?

d.) How many total calories are expended after 15 minutes of pedaling at 200 watts?

e.) What is the percentage of output in kilocalories relative to the input in kilocalories?

a. Generally 1.2 calories are expanded per minute at rest in an average body weight of 70kgs.

b. If the exercise is bicycle, MET is 4.

calories/min = 0.175 × MET × weight

Let us consider average weight as 70kgs

= 0.175×4×70

= 49

c. It is about 600k.cal

d. energy(k.cal)= average power(w)× duration(hours)×3.6

= 200 × 0.15 × 3.6

= 108

e. For every 12 calories we put into food, we deliver 1 calorie of nutrition.
