The problem in this study originated from the low ability of the Smash of the men’s volleyball players in the Palembang City MBVC Club, such as Smash not being on target, leaving the field and blocked. The low ability of Smash is influenced by several exogenous factors, including Arm muscle power and Confidence in Smash ability, and. This research is quantitative with a path analysis approach. The population in this study were all male volleyball players from the Palembang City MBVC Club, amounting to 20 people. Sampling uses a saturated sampling technique, so it samples all populations. The arm muscle instrument uses One Hand Medicine Ball Put, uses a Likert scale model questionnaire and Smash ability with the Smash test. The results showed that, (1) there was a direct effect of arm muscle power on the ability of Shash, with py1 = 0.386 or 14.90% (2) there was a direct trust effect on Shash ability,, with py2 = 0.382 or 14.59% (3) There is an indirect effect of arm muscle power on the ability of Smash through self confidence, with py21 = 0.1574 or 15.74%.

Abstract

This study employs a quantitative approach with a correlational design. It is designed to examine the relationship between emotional intelligence and reaction speed in relation to groundstroke ability. The sample for this study was drawn from the population using purposive sampling. The purposive sampling technique involved a sample size of 10 participants. The research instruments for emotional intelligence and reaction speed were measured using the Ruler Drop Test, whilst groundstroke performance was assessed using a specific test. The data analysis techniques employed in this study included descriptive and inferential statistics. Inferential analysis was conducted using the Pearson Product-Moment correlation test. Results of the Pearson Product-Moment correlation test. The results of the study on the relationship between emotional intelligence and reaction speed showed a correlation coefficient of -0.479 with a significance level of 0.161 (where 0.161 > 0.05); the relationship between emotional intelligence and groundstrokes showed a correlation coefficient of 0.608 with a significance level of 0.062. Furthermore, the relationship between reaction speed and groundstrokes yielded a correlation coefficient of -0.766 with a significance level of 0.010. A correlation coefficient of -0.766 indicates a strong negative relationship between reaction speed and groundstrokes. The significance value of 0.010 is less than 0.05. Given that the R-squared value is 0.661, it can be concluded that the combined influence of reaction speed and emotional intelligence on groundstrokes accounts for 66.1 per cent of the variation, whilst the remaining 33.9 per cent is influenced by other factors not examined in this study.
