Abstract

This research is quantitative descriptive research with aims 1). To determine the contribution of arm muscle strength to volleyball serving ability, 2). To determine the contribution of hand-eye coordination to volleyball serving ability. 3). To determine the contribution of abdominal muscle strength to volleyball serving ability. 4) To find out together the strength of the arm muscles, eye hand coordination and abdominal muscle strength on the ability to serve in volleyball among UPT SPF students at Bulukumba State Middle School. The independent variables in this study were arm muscle strength, hand eye coordination, and abdominal muscle strength, while the dependent variable was upper serve ability. The population in this study was all students in class VII-VIII UPT SPF SMP Negeri 29 Bulukumba totaling 60 students with 30 male students used as samples using a probability sampling technique (random sampling). The data collection techniques used were giving arm muscle strength tests (push ups), hand eye coordination tests (throwing and catching ball tests), and abdominal muscle strength tests (sit-ups), observation and documentation. Descriptive data analysis techniques and inferential statistical analysis using correlation and regression tests. The results of correlation and regression tests related to the contribution of arm muscle strength to the ability to serve in volleyball showed R2= 0.756 (P=0.000), the contribution of eye and hand coordination to the ability to serve in volleyball showed R2= 0.684 (P=0.000), the contribution of abdominal muscle strength to volleyball service ability shows R2= 0.534 (P=0.000) and the integrated contribution of arm muscle strength, abdominal muscle strength, and hand eye coordination to volleyball service ability shows R2= 0807 (P=0.000). So it can be concluded that arm strength, hand-eye coordination, and abdominal muscle strength each have a linear contribution to the volleyball serving ability of UPT SPF students at SMP Negeri 29 Bulukumba. And there is a significant contribution from the combination of arm muscle strength, hand eye coordination and abdominal muscle strength to the volleyball service ability of UPT SPF students at SMP Negeri 29 Bulukumba.

Abstract

The tennis serve is a critical aspect of gameplay, requiring both technical skill and physical fitness. This study investigates the impact of three physical components arm power, hand-eye coordination, and leg muscle strength on the performance of tennis serves. Using a correlational research design, data were collected from 20 beginner tennis players aged 16–18 years in Makassar Arm power was measured through a medicine ball throw test, hand-eye coordination via the hand wall toss test, and leg muscle strength using a leg dynamometer. The Hewitt Tennis Achievement Test was employed to evaluate serve accuracy and consistency. The findings reveal that all three physical components significantly influence service performance (p < 0.05). Arm power enhances ball speed, hand-eye coordination improves serve accuracy, and leg muscle strength supports stability and energy transfer during the serve motion. Combined, these factors explain a significant proportion of variance in service effectiveness. This study emphasizes the need for comprehensive training programs focusing on these physical attributes to improve serve performance among beginner tennis players. These results provide actionable insights for coaches and athletes aiming to optimize serve efficiency, highlighting the interplay between strength, coordination, and stability as foundational elements of successful tennis serve.
