Abstract

The purpose of this study was to determine the influence of isotonic and isokinetic weight training on vertical jumping proficiency as measured by a modified vertical jump. The subjects were college students enrolled in the Fitness and Lifetime Activities Program at South Dakota State University in Brookings, South Dakota. Isotonic and isokinetic training were assigned to the two experimental groups with the third group serving as controls. Training for the experimental groups consisted of isotonic circuit training on a Universal weight machine and isokinetic training on a Leaper machine. Data analysis included a reliability and reproducibility assessment, and a one-way analysis of variance to determine whether significant mean changes had occurred between the groups means. Tukey's w-procedure was used to identify the source of significant changes. All statistical tests were conducted at the .05 level. Mean scores for both experimental groups were significantly different from those of the controls. Although there was no significant difference between mean performances of the two experimental groups, the isokinetic group experienced a higher level of improvement (8. 7% >7.3%).
