Leg Power, Arm Strength, and Smash Accuracy in Female Volleyball Athletes: A Correlational Study

Abstract

This study aimed to investigate the correlation between leg power, arm strength, and smash accuracy in female volleyball athletes. This study highlights the significance of having both strong leg muscles and arm strength to achieve high levels of smash accuracy in female volleyball athletes. A total of 15 female volleyball players, aged 15 years, participated in this study. Leg power was measured using a Jump DF, arm strength was measured using a pull and push dynamometer, and smash accuracy was measured using a smash test from Robert E. Laveage. Correlation analysis was performed to examine the relationship between the variables. The data analysis technique used in this study was regression analysis at a significance level of 5%. The results of the data analysis showed that at a significance level of α = 5%, the obtained Ftabel was 4.67. The research findings revealed that: 1) the correlation coefficient rx1y was Fscore = 6.028 > Ftabel 4.67, indicating a significant relationship between leg power and smash accuracy; 2) the correlation coefficient rx2y was Fscore = 18.059 > Ftabel 4.67, indicating a significant relationship between arm strength and smash accuracy; and 3) the correlation coefficient ry(x1.x2) was Fscore = 6.797 > Ftabel 3.88, indicating a significant relationship between leg power, arm strength, and smash accuracy. In conclusion, this correlational study provides evidence that both leg power and arm strength are positively correlated with smash accuracy in female volleyball athletes. Coaches and trainers can use this information to design training programs that focus on improving leg power and arm strength to enhance the performance of female volleyball players in the sport.
