The study investigated the relationship between maximum isometric strength and relative isotonic endurance of athletes with different levels of strength. Subjects were 120 male college athletes who were divided into three equal groups based on the sums of their maximum isometric strength scores over the entire study. Group I was composed of the 40 strongest subjects, while Group III contained the 40 weakest subjects. The remaining 40 subjects were placed in Group II, or middle level strength. All subjects were tested for maximum isometric strength on three successive days using the flexor muscles of the forearm. Relative isotonic endurance was also performed on three successive days by all subjects using a modified arm lever ergometer, the relative load for each test being determined from the maximum isometric strength test for that particular day. Relative loads used in the present study were 35%, 40%, and 45% of maximum isometric strength. Results indicated that there was a positive and significant relationship between maximum isometric strength and relative isotonic endurance for the entire group at all relative loading levels. There was also a positive relationship between maximum isometric strength and relative isotonic endurance for each experimental group at all relative loading levels. However, only correlations for the high strength group reached the level needed for significance. Verf.-Referat
