An attempt has been made to determine the influence of several physical activities upon the serum cholesterol of 133 young adult males, who were randomly selected to participate in 10-week programs of cross-country running, golf, tennis, tumbling-gymnastics, wrestling, and weight training, and whose cholesterol values were compared with those of a control group. The findings as examined by analysis of variance suggest that different types of physical activity influence cholesterol concentrations in different degrees: subjects who participated in a vigorous and dynamic type of activity showed a significant decrease, whereas subjects who participated in a vigorous but static type of activity experienced no significant reduction during the experimental period.
