ABSTRACT

The purpose of this study is to identify physical factors related to the serve accuracy in Yogyakarta wheelchair tennis players (WT). Method: This research is a quantitative study using correlation analysis conducted by field test. The participants were the best wheelchair tennis athletes with seven men and three women 156-167± cm, weight 50-70± kg, age 31-35. Each athlete performed neuromuscular tests consisting of: isometric handgrip strength; serve accuracy (Hewitt test); sprint tests 5m, 10m and 20m (using and not using rackets); agility (using and not using rackets); medicine ball throw (serve, forehand and backhand movement); and endurance test specific to WT. Results: The highest correlation was found from medicine ball throw serve (p = 0.001; r = 0.874), forehand (p = 0.004; r = 0.811) and backhand (p = 0.013; r = 0.747), medicine ball throw showed a positive correlation with serve accuracy. The physical parameters of the medicine ball throw can explain 100% of the service accuracy level (Nagelkerke R Square = 1.00) and have a percentage of being correct 100% through the logistic regression test classification table. Conclusion: It is recommended that coaches and physical trainers incorporate medical ball throwing exercises into the training program of WT players due to benefits of transferring serve accuracy.
