Abstract

Purpose of The Study. To investigate the effects of an 8-week plyometric depth jump training program on badminton smash accuracy in amateur athletes and examine the relationship between lower body power development and overhead striking precision. Material and methods. Twenty-four amateur badminton athletes (14 males, 10 females; age: 19-25 years) were randomly assigned to experimental (n=12) and control (n=12) groups. The experimental group performed progressive plyometric depth jump training three times per week in addition to regular badminton practice, while the control group maintained only regular practice. Platform heights progressed from 40-55 cm over 8 weeks. Smash accuracy, vertical jump performance, ground contact time, and movement efficiency were assessed pre- and post-intervention. Results. The experimental group demonstrated significant improvements in smash accuracy (29.6%, p < 0.001, d = 2.21), vertical jump height (13.2%, p < 0.001, d = 1.78), and ground contact time (15.7% reduction, p < 0.001). Strong correlations were observed between vertical jump improvements and accuracy enhancements (r = 0.76, p < 0.001). The control group showed minimal changes (4.4% improvement in accuracy, p = 0.089). No significant gender differences were found in adaptation rates (p = 0.085). Conclusions. An 8-week plyometric depth jump training program significantly improves badminton smash accuracy in amateur athletes, suggesting that enhanced lower body power development directly contributes to improved striking precision. The findings support integrating structured plyometric training into regular badminton practice for technical skill enhancement.

Abstract

Study Purpose. Articulate the key intersection points and differences between motivational indicators that can influence the occurrence of motivation to learn in physical education learning at school. This study was designed to examine the effect of physical activity participation in organized schools on indicators of learning motivation in physical education learning. Materials and methods. Assessment of physical activity based on a questionnaire using the International Physical Activity Questionnaire (IPAQ) and motivation to learn physical education based on research on six indicators that have passed the Expert Judgment stage. Participants consisted of 202 grade 10 students who attended physical education classes at SMAN 1 Sukoharjo, Central Java. The greater the effect of physical activity on participating students to increase the overall learning motivation is higher. Perceptions of learning motivation indicators related to physical activity items. Results. In both of these influence assessments, indicators of learning motivation can be said to be influenced by several physical activity items. Changes in physical activity can predict changes in learning motivation, except for Learning Tools and Teaching Methods. In particular, physical activity items can affect indicators of students' environmental conditions. Conclusion. There is a dynamic influence between the participation of learning motivation indicators in physical education learning on student activities at school.

Abstract

Background The background of this research lies in the need to understand the physical condition of students participating in futsal extracurricular activities, as optimal physical fitness is essential for supporting performance in a fast-paced sport such as futsal. Evaluating students’ physical condition is necessary to identify their strengths and weaknesses across several fitness components relevant to gameplay. Objectives The objective of this study was to determine the overall level of physical condition among futsal extracurricular students at YLPI Perhentian Marpoyan Junior High School. Methods This research employed a descriptive quantitative design. The participants consisted of 15 futsal extracurricular students selected through a total sampling technique. Data were collected through a series of physical fitness tests, including a 30-meter sprint test to measure speed, a shuttle run test to assess agility, a standing long jump test to measure leg explosive power, a wall squat test to measure muscular endurance, and a 15-minute run test to evaluate cardiorespiratory endurance. To get an overall classification, the test results were put into standardized scoring categories and then analyzed. Results The results indicated that the students achieved an average final physical condition score of 2.5, rounded to 3, which is categorized as Fair. These findings indicate that although students possess basic physical abilities, their overall physical condition remains insufficient to meet the demands of futsal performance. Conclusion The study concludes that students require improvement through structured and consistent training, which points to the importance of enhanced fitness development programs within the extracurricular futsal setting.
