Aerobic exercise study. Excess postexercise oxygen consumption (EPOC) describes energy expended during the body’s recovery period immediately following aerobic exercise. The Journal of Sports Medicine and Physical Fitness (Dec. 1994) published a study designed to investigate the effect of fitness level on the magnitude and duration of EPOC. Ten healthy young adult males volunteered for the study. Five were endurance trained and made up the fit group; the other five were not engaged in any systematic training and constituted the sedentary group. Each volunteer engaged in a weight-supported exercise on a cycle ergometer until 300 kilocalories were expended. The magnitude (in kilocalories) and duration (in minutes) of the EPOC of each exerciser were measured. The study results are summarized in the following table:

a. Conduct a lest of hypothesis to determine whether the true mean magnitude of EPOC differs for fit and sedentary young adult males. Use α = .10.
