Calculate the amount of work and power performed during one

Calculate the amount of work and power performed during one minute of treadmill exercise by a 70-kg subject running at 180 meters/min up a 5% grade. (Vo2 ml^.kg^.min)

Solution

Answer:

We have to Calculate the amount of work and power performed during one minute of treadmill

To calculate total vertical distance traveled :

Treadmill speed xPercent Grade x Exercise time

Treadmill speed = 180 m/min,

Percent Grade = 5% or 0.05

Exercise time = 1 mins

= 180 x 0.05 x 1

= 9

Work = body weight (kg) x total vertical distance traveled

= 70 kg x 9 m

= 630 kpm

Work = 630 kpm

Power = work / minutes

= 630 / 1

= 630 kpm/min

Power = 630 kpm/min
