The relationship between explosive power, elbow angle, and jump height with smash accuracy in volleyball games: Correlational studies

Abstract

Background. Smash is synonymous with powerful punches and swift dives. Accuracy stands as the primary factor that holds significant importance. Purpose. The purpose of this study is to investigate the relationship between the independent variables, namely explosive power, elbow angle, and jump height, and the dependent variable, which is smash accuracy. Material and Methods Descriptive research design with correlational methods. This research involved a group of 15 male student athletes, whose age (M ± SD = 21.27 ± 1.163 years) and height (M ± SD = 167.67 ± 1.877 cm) were recorded. The sampling technique used purposive sampling, with certain criteria. Prerequisite tests such as normality test and linearity test were conducted, followed by hypothesis testing. The data was analyzed using SPSS 26.0. Results The results demonstrate a significant and simultaneous asscosiation between the independent variable and the dependent variable, as indicated by the observed significance value of 0.015 <0.05. The data output reveals a simultaneous correlation coefficient of R = 0.776, with a determination coefficient of Rsquare = 0.601, indicating that 60.1% of the variation in the dependent variable can be explained by the independent variables. The remaining 39.9% is attributed to and explained by factors other than the independent variables. Conclusions The findings and discussion of the research demonstrate a noteworthy association between explosive power, elbow angle, and jump height, and the accuracy of smashes in volleyball. As a result, this study presents substantial evidence supporting the significant contributions of explosive power, elbow angle, and jump height to smash accuracy.
