A 60kg woman does a step-up/step-down task using a 25cm platform. A full step cycle consists of a step-up a followed by a step-down. During each step-up assume she is lifting her entire mass with one leg. Ignoring accelerations and motion in the horizontal direction a. How many step-ups would the woman need to do to expend at least 1kCal of energy? b. How quickly (steps/min) would she need to do the activity if the goal was expend at least .05kCal/s? (assume step up and down time is the same)
