Question

What would your calorie-expenditure be if you weighed 150 pounds and you spent an hour gardening? A. 260 calories B. 216 calories C. 108 calories D. 165 calories

Answer 1

The answer would be B.                                  

Answer 2

Answer: B

Explanation:

Energy expenditure (calories/minute) = 0.0175 x MET (from chart for Gardening) x weight (in kilograms)

(To find out your weight in kilograms, simply divide your weight in pounds by 2.2)

MET = 3.02 (from Chart for Gardening)

MET for Gardening/hr = 3.02 x 60mins = 181.2

Weight (in kg) = 150 ÷ 2.2 = 68.18kg

So applying the formulae above, we have:

Energy expenditure = 0.0175 x MET x Weight

Energy Expenditure = 0.0175 x 181.2 x 68.18 = 216.00 ~ 216calories (ANS)
