Purpose: The purpose of th is study was to determine whether arm strength can be improved after eight weeks with: isotonic, isometric, and or heterotonic exorcises. An additional problem was to determine if there were any differences in the increase of strength between the three different methods of exercise. A review of related literature indicated that muscular strength can be increased by progressive resistance exercises, but controversy still exists concerning the most efficient way in which it can be achieved. Procedures: Three groups of twenty subjects each participated in an experimental study at Wilmot Junior High School, Deerfield, Illinois. The subjects were given arm strength tests, and upon completion of the pre-test were given the choice of participating in on eof the three methods of exercise: isotonic, isometric, and heterotonic conditioning. Each group was placed on an eight week training program. The subjects met twenty four times during the eight week training program. Each group used strength developing exercises which closely paralleled the other groups. At the end of the training period, the groups were retested. Results: After reviewing the results it was revealed that all three exercise methods increased am strength, however, none of the methods showed a significant gain over the others.
