Coaches of wrestling have long been interested in the physiological changes which occur in a wrestler during a competitive season. This concern has been stimulated by the controversy over the effects of weight reduction among wrestlers prior to and during a season of competition. The practice of weight reduction has prompted research that follows wrestlers through the competitive season. Although studies have been completed centering around changes in muscular strength in relation to body weight loss, few have been conducted studying the cardiovascular changes which occur during a season of competitive wrestling. A search of the literature indicated that the ability of most athletes to perform effectively and efficiently depends on the efficiency of the heart to supply oxygen to the muscles. Because the research studying the cardiovascular responses of wrestlers during a season of wrestling is limited, it was felt that a study was needed to investigate these responses in addition to the changes in strength, muscular endurance, percent body fat, and weight. The present study was directed towards this end.
