I have decided to perform squat jumps as a good at home exercise during the stay at home order. In the morning I ate two donuts (190 kilocalories each) and would like to know how many squat jumps I need to perform in order to burn off the donuts? For each repetition, I squat down so my center-of-mass is 0.5 m above the ground and at the top of my jump my center-of-mass is 1.6 m above the ground. One kilocalorie equals 4,184 Joules. My body mass is 84 kg. My gross efficiency is 23%. One repetition is jumping up to 1.6 m and coming back down to 0.5 m (so I am performing concentric and eccentric work).
Over the next few weeks I become very good at performing squat jumps and my efficiency increases to 28%. Will I need to perform more or less repetitions now to burn off those donuts? Describe one strategy to reduce the number of required squat jumps. Be sure your description appropriately incorporates biomechanical concepts.
