A Review of Muscular Efficiency Studies for Different Exercises

In this review study, information on efficiencies and characteristics of different exercises is presented with the goal of using the information for modeling extra-vehicular activity (EVA). Muscle activation is reported for running, walking, and cycling. The deviation and uncertainties in efficiency will be assessed along with effects of workload, rate of exercise, training, and various physiological parameters. The uncertainty involved in using VO₂ consumption as a measure of metabolic rate is discussed. The information reported will be related to efforts to analyze exercises to simulate EVA on Earth.
