The Effect of a Three-Month Physical Fitness Program on Serum Free Cholesterol.
Montgomery, D. L.; Ismail, A. H.
This study investigates the effect of a three-month physical fitness program on serum-free cholesterol concentration in four age and fitness adult groups. Twenty-four men were divided into the following groups: (a) young, low-fit; (b) old, low-fit; (c) young, high-fit; and (d) old, high-fit. All subjects had normal resting glucose and triglyceride levels and participated in a physical fitness program consisting of calisthenics, jogging, and recreational activities. Subjects were tested on a treadmill at the beginning and at the end of the three-month program, and venous blood samples were drawn at four stages of metabolic stress: rest, submaximal, maximal, and recovery. The analysis of variance technique was used to determine significant differences between pre- and post-tests, fitness levels, age groups, different metabolic stress levels, and the significant interactions of various factors. Data suggest the following conclusions: (a) there is no significant change in serum-free cholesterol level due to a three-month physical fitness program; (b) the high-fit group had a significantly lower free cholesterol level than the low-fit group did; (c) there was no significant difference between fitness groups for the percent-free cholesterol; (d) there were no significant differences between age groups for the free cholesterol or percent-free cholesterol; and (e) acute physical exercise increases the absolute and percent-free cholesterol from the resting state through the maximum exercise state.
