Question:

In a common test for cardiac function (the €œstress test€) the patient walks on and inclined treadmill (Fig. 6-46). Estimate the power required from a 75-kg patient when the treadmill is sloping at an angle of 15o and the velocity is 3.3 km/h. (How does this power compare to the power rating of a lightbulb?)
