Aim of this study is to analyze the effect of a 8 week-explosive power training on some performance parameters of students who studying in sports high school. A total of 101 healthy male canoeist students who studying in sports high school volunteered to participate in this study. students were randomly divided into two groups and test (N = 51) and control (N = 50) groups were formed. Explosive power trainings were applied to test group during 8 weeks as 30-minute trainings for 3 days a week in addition to canoe training and control group continued only canoe training. All data were obtained twice as pre-test and post-test before and after training. Four line sprint test, standing long jump test and 20m sprint test were used to determine performances of the subjects When results of the study are examined, it is seen that explosive power trainings applied during 8 weeks had statistically significant effects in favor of the post-tests for 20m sprint, sprint-agility and standing long jump performances pre-test and post-test results (P<0.05). In addition, when post-test results of test and control group were compared, it was found that test group's 20m sprint, sprint-agility and standing long jump performances post-test results showed statistically more significant improvement than control group's post-test results (P<0.05). These results confirm our expectations before the research. Consequently, it can be thought that explosive power trainings applied have positive effects on 20m sprint, sprint-agility and standing long jump performances.
