Developing a New Model of Resistance-based Strength Train and Its Effects on Junior Athletes' Tennis Serve Performance

This study was aimed at developing a new model of resistance-based strength training for junior tennis athletes and examining its effectiveness on their serve performance compared to traditional model of training. It is a Research and Development study focusing on developing, validating, revising, and testing the model of training. In testing phase, effectiveness test was accomplished to examine the effectiveness of the new training model and compared to the effectiveness of the traditional model. There were 60 junior athletes contributing to this study. The data were gathered by distributing questionnaires to reveal the convenience and attractiveness of the model developed and using Collang Smart Tennis Racket Sensor Tracker Motion Analyzer to reveal the tennis athletes' serve performance. The data were analyzed by employing descriptive statistic and t-test. In terms of convenience and attractiveness, this study revealed that the use of resistance training for junior tennis athletes showed good results. T-test proved that this new model was more effective in improving players' serve speed compared to traditional model was. Thus, researchers concluded that the new model of resistance-based training can be implemented to increase tennis junior players' serve speed.
