Question

Each time he does one pushup, Jose, who has a mass of 89kg, raises his center of mass by 25 cm. He completes an impressive set of 150 pushups in 5 minutes, exercising at a steady rate. (NOTE: don't forget to use human body efficiency into the equation.)

If we assume that lowering his body has no energetic cost, what is his metabolic power during this workout?

In fact, it costs Jose a certain amount of energy to lower his body-about half of what it costs to raise it. If you include this in your calculation, what is his metabolic power?
