The Comparative Study of Leg Muscle Isokinetic Strength in Sprinter and Jumper in Athletics. Exercise Science, 8(3): 361-372, 1999. The purpose of this study was to compare leg muscle isokinetic strength in athletic sprinters and jumpers, and to provide the data for training methodology, rehabilitation and injury prevention. The subjects selected for this study were composed of fifteen elite sprinters and fifteen jumpers in athletics. In order to obtain these purpose, we used Cybex-II at the speed of 30°/sec and knee extended fully to measure isokinetic strength. The variables measured were dorsiflexion and plantarflexion absolute and relative strength between sprinters and jumpers. Another measure carried out same method within sprinters and jumpers. The data were analyzed utilizing t-test and ANOVA. The alpha level of statistical significance was set at p<.05. On the basis of the results analyzed in this study, conclusion were drawn as follows: (1) There was no significant difference in dosiflexion and plantarflexion of leg muscle between sprinters and jumpers. (2) The dorsiflexion and plantarflexion between left and right leg muscle was no significant difference, but some unbalance were found in sprinter players. (3) Within sprinters, 100m players were highest in absolute and relative dorsiflexion and plantarflexion. (4) Within jumpers, the high jumper was high in absolute and relative plantarflexion, whereas the Cripple jumper was high in relative dorsiflexion.
