Abstract

This thesis is entitled “The Effect of Hurdle Jump Training on Leg Muscle Power Ability in Volleyball Extracurricular Participants at SMPN 234 East Jakarta.” Thesis, Faculty of Teacher Training and Education, Universitas Islam “45” Bekasi. This study aims to determine the effect of the hurdle jump training method on the leg muscle power ability of volleyball extracurricular participants at SMPN 234 East Jakarta. The method used in this research is an experimental method with a onegroup pretest-posttest design. The population in this study consisted of students aged 13–15 years, totaling 40 students. The sampling technique used was cluster purposive sampling, resulting in a sample of 20 volleyball extracurricular participants at SMPN 234 East Jakarta. Based on hypothesis testing of variables X and Y obtained through Vertical Jump results, this study is supported by the t-test results, which show that the calculated t-value (20.11) is greater than the t-table value (2.093). This result indicates that Ho is rejected, meaning that there is a significant difference in the hurdle jump training of volleyball extracurricular participants before and after the training was given. This study concludes that there is an effect of hurdle jump training on improving leg muscle power ability in volleyball extracurricular participants at SMPN 234 East Jakarta. The results of this study also provide recommendations for coaches to design more varied and intensive training programs to optimize player performance
