the effect of 6 week nordic hamstring exercise on sprint and jumping performance

The purpose of this study was to examine the effect of 6-week eccentric hamstring strength training on vertical jump and sprint performance. there were 19 male active participants in the study, of which 10 were in the experimental group and 9 in the control group. pre-test and post-test measurements of the participants in the study were taken. participants' 5-m, 10-m and 30-meter sprint, vertical jump were measured. the spss 17.0 package program was used in the analysis of the data, and the test values of the participants were analyzed with the wilcoxon signed ranks test. according to the findings obtained from the research results, in the statistical comparison of the 5-m, 10-m and 30-meter sprint test results of the experimental group participants before and after the training, there was no significant difference between the 5-m sprint pre-test and post-test values of the participants in the research (p> 0.05), there was a significant difference between the 10m and 30m sprint test pre-test and post-test values (p< 0.05). as a result, nordic hamstring training small to moderately improved both sprint and vertical jump performance.
