Abstract

This study aims to determine the correlation between leg explosive power and shooting quality in soccer games. The research method uses a quantitative approach with a correlational design. The research sample consisted of 30 male students selected through a purposive sampling technique. The instruments used included a standing broad jump test to measure leg explosive power and a shooting test to assess shooting quality. The results of the descriptive analysis showed an average leg explosive power of 2.079 meters and an average shooting quality of 1.027. The normality test obtained a significance value of 0.46 for explosive power and 0.65 for shooting, which indicates that both variables are normally distributed. The linearity test produced a Sig. value of 0.724 > 0.05, so the relationship between the variables is declared linear. The results of the correlation test using SPSS showed a value of r = 0.678 with Sig. 0.000 < 0.05, which means there is a strong and significant relationship between leg explosive power and shooting quality. Thus, it can be concluded that the higher the leg explosive power, the better the shooting quality in soccer games

Abstract

The purpose of this study is to explore the effectiveness of dumbbell training on the ability to serve over the top of the volleyball game. The population in this study consisted of 30 students from SMA Negeri 6 Kendari. Sampling was done through a total sampling technique, which resulted in a sample of 30 people. The research instrument was the upper service ability test, the training method used was dumbbells. By applying statistical analysis, the t-test was carried out using SPSS version 25 software, it was revealed that there was a positive influence between arm muscle strength and upper service ability, with a value (t count) of 2.218 and a value that had a significant level of 0.000 <0.05. It was proven that there was a percentage increase of 20.05% in the pre-test and post-test after doing arm muscle strength training. These results mean the effectiveness of dumbbell training on the ability to serve over the top of the volleyball game.
