Abstract

This study aims to analyze the relationship between leg muscle power, arm strength and wrist flexibility on the Smash accuracy of male and female extracurricular volleyball students at SMA Negeri 15 Bandar Lampung. The method used in this research is quantitative correlational with a sample of 30 students, 15 male students and 15 female students. Data was collected through broad jump tests, push and pull dynamometer, goniometer, and position-based Smash tests. Data analysis was carried out using the Pearson correlation test, multiple correlation, as well as through the prerequisite tests for normality and linearity. The results of the multiple correlation test show that there is a strong relationship between leg muscle power, arm strength and wrist flexibility and smash accuracy for both male and female students. The results of the multiple correlation test show R = 0.740 for boys and R = 0.693 for girls, indicating a simultaneous relationship. The simultaneous contribution of these three variables to smash accuracy for male students was 55%, while for female students it was 48%, indicating a fairly strong contribution from the three variables to smash accuracy and significance (p<0.05).

Abstract

This study aimed to determine the effect of wall-rebound training on underhand passing skills in volleyball among students participating in the volleyball extracurricular activity at SMA Negeri 10 Bandar Lampung. The research employed an experimental method with a pre-test and post-test design. The sample was divided into an experimental group that received wall-rebound training and a control group that received conventional training. The research instrument was an underhand passing skill test in volleyball. Data were analyzed using the normality test, homogeneity test, and t-test with a significance level of 0.05. The results showed that the data were normally distributed and homogeneous. The first hypothesis test indicated a significant effect of wall- rebound training on underhand passing skills in the experimental group, with t- value = 19,379 > t-table = 2.145 and Sig. = 0.000 < 0.05. The second hypothesis test revealed a significant difference in underhand passing skills between the experimental group and the control group. Furthermore, the third hypothesis test showed a significant difference in the improvement of underhand passing skills between the experimental group and the control group, with t-value = 2.107 > t- table = 2.048 and Sig. = 0.044 < 0.05. It can be concluded that wall-rebound training is effective in improving underhand passing skills in volleyball among students participating in the volleyball extracurricular activity at SMA Negeri 10 Bandar Lampung
