. In a common test for cardiac function (the “stress test”), the patient walks on an
inclined treadmill. Estimate the power required from a 75-kg patient when the
treadmill is sloping at an angle of 12° and the velocity is 3.1 km/h.

The power required from a 75-kg patient when the treadmill is sloping at required speed is 131.58 W.

Parallel force on the patient

The parallel force on the patient is calculated as follows;

F = mg sinθ

F = (75 x 9.8) x sin(12)

F = 152.82 N

Average power required

P = FV

where;

  • V is speed  = 3.1 km/h = 3.1/3.6 = 0.861 m/s

F = 152.82 x 0.861

F = 131.58 W

Thus, the power required from a 75-kg patient when the treadmill is sloping at required speed is 131.58 W.
