Abstract

Research Problems: Muscle explosive power is one of the dominant physical components in the sport of pencak silat. Research Objective: This study aims to examine the effect of plyometric training in increasing the explosive power of arm and leg muscles in adolescent pencak silat athletes who are members of the Special Athlete Class (KKO) program. Methods: This study is a quasi-experimental study using one-group pretest-posttest. The number of samples involved in this study was 17 adolescent pencak silat athletes who are actively registered in the Special Athlete Class (KKO) program. Arm muscle explosive power was measured through the Medicine Ball Throw Put Test (MBTP), while leg muscle explosive power was measured using the Standing Broad Jump Test. Data analysis used the Shapiro-Wilk normality test and paired sample t-test with a significance level of 0.05. Results: Arm muscle explosive power increased from 2.07 ± 0.24 m to 2.24 ± 0.28 m (t(16) = 6.596; p < 0.001), while leg muscle explosive power increased from 4.51 ± 0.60 m to 5.14 ± 0.83 m (t(16) = 3.607; p = 0.002). The effect sizes obtained were categorized as large (Cohen's d = 1.60 for arm muscles and 0.87 for leg muscles). Conclusion: Plyometric training significantly increased arm and leg muscle explosive power in adolescent pencak silat athletes participating in the Special Sports Class (KKO) program. Plyometric training can be recommended as a form of routine training to optimize the physical capacity and performance of adolescent pencak silat athletes.

Abstract

In addition to improving motivation and self-confidence, the positive reinforcement–based mentoring activities also brought significant changes to the learning dynamics in the field. Students who were previously passive and hesitant began to show greater confidence when attempting the forearm passing technique. Each form of praise and feedback provided encouraged students to repeat the movement with increased assurance. This was evident from the growing number of students who voluntarily stepped forward to practice the technique in front of the group. Positive changes were also observed in the quality of interaction between students and lecturers. The reinforcement approach created a more dialogic and supportive learning atmosphere. Students felt appreciated, making them more receptive to corrections and more responsive in improving their technical errors. The training environment became more conducive and collaborative, as students supported one another whenever progress was demonstrated by their peers. Furthermore, observational results indicated a significant improvement in the students’ forearm passing accuracy, particularly in body positioning, arm swing, and movement coordination. This improvement was not only seen in students who initially displayed adequate skills but also in those who previously faced limitations. This demonstrates that the implementation of reinforcement has an equal and inclusive effect on all participants. Students also expressed that this approach made them feel more comfortable and motivated throughout the learning process. They perceived positive reinforcement as providing psychological safety, as mistakes were not regarded as failures but as essential elements of the learning process. This condition fostered a more humanistic learning climate and encouraged students to continually engage in self-improvement. Thus, the outcomes of this community service program not only enhanced students’ technical skills but also developed a more positive, supportive, and sustainable learning culture. This mentoring model has the potential to be applied to other volleyball techniques as well as to other sports-related courses that require a motivational approach
