Question

80 kg man walks at 3 miles per hours for 40 minutes. How many kilocalories did he expend 55 kg woman walks on a 10% grade at 80 meters per minute how much oxygen is she using per minute. If she did his for 30 minutes how many kilocalories would she expend 60 kg woman and a 90 kg man ride a monarch cycle at the 2 kilopon setting at 60rpms. What is the oxygen uptake for each in litters per minute. What is the exercise intensity in metts for each person Met is 2.5 per kilogram per minute. Whose working harder

Explanation / Answer

1) The weight og the man in pounds is approximately 180 pounds. from the calories burnt data,

For walking at 3mph for 40 mintues , the data says the man would burn about 200 calories which is about 0.2 kilcalories.

2)For every 1 percent of grade, you increase your calories burned by about 12 percent..

1 m/s =2.2394 mpa

80 m per min =) 1.333m/s

Therefore 1.33m/s is equal to 2.9858 mph(1.33*2.2394)

From the data we have , a person of weight 55kgs walking on a horizontal for 30 minutes at a speed of approximately 3 mpa burns about 96 calories.

Now if the same person walk on an incline of 10% gradient, we have

calories burnt = 96* 1.12*1.10 =) 118.72 calories.

3)For this question , the data at the specific settings is not avaliable.
