Abstract

PROBLEM. The problem was to determine the effects of heavy resistance and light resistance isotonic exercises on the speed of arm movement and shot-putting ability. It was the purpose of this study to determine which of the two types of strength developing exercises, one performed with heavy resistance and few repetitions and the other with light resistance and a moderate number of repetitions, significantly affects the speed of the arm movement used in putting the shot. PROCEDURES. The thirty-four subjects used in this study were members of a regularly scheduled physical education service classes at Northern Illinois University. All subjects were tested on shot-putting ability by giving them six trials with the twelve pound shot. Subjects were also tested on speed of arm movement by the Athletic Performance Analyzer. After this initial testing, they participated in a six week program of weight training. Subjects wore equally divided into two groups on the basis of the McCloy Strength Test. Group I (heavy resistance group) performed three sets of five repetitions at each class meeting while Group II (light resistance group) performed three sets of thirty repetitions. Each subject was always exercising with maximum resistance for his particular number of repetitions. The initial and final tasting for the shot put, arm speed, and McCloy Strength Test were conducted in two hourly sessions. Within group comparisons were made by comparing the means of the initial tests with the means of the final tests. A series of "t” tests were run on the data. The difference between Group I and Group II was determined by comparing the final means of the three tests. RESULTS. Both the heavy resistance and the light resistance weight training programs increased strength, shot-putting ability, and speed of arm movement. The t values for the above tests all indicated significance at the .01 level of confidence with sixteen degrees of freedom. The *t” tests however, showed no difference between the heavy resistance and the light resistance programs for Improving strength, shot-putting ability, and am speed. CONCLUSIONS. It was concluded that both heavy resistance and light resistance weight training exercises are effective methods of Increasing arm strength, shot-putting ability, and am speed. Also, it was concluded that there is no statistically significant difference between the heavy resilience end the light resistance programs for improving performance on the above three tests.
