The Effectiveness of a Football-Based Psychological Skills Training Program on Adolescents in the Indonesian–Malaysian Border Area: An Experimental Study in Entikong

Soemardiawan Soemardiawan — 2026-04-19

The Indonesia-Malaysia border region faces complex socio-economic challenges, including limited access to structured education and training. For this purpose, efforts to build psychological skills such as emotion regulation, stress management, and self-confidence are important to build resilience in the face of competitive and social pressures. This study aims evaluated the effectiveness of a football-based psychological skills training program for students in this area. Using an experimental design with control and experimental groups, 60 male students aged 15–16 participated in a 16-week program combining training sessions and football competitions. Psychological skills were measured with the Psychological Skills Inventory for Sports (PSIS-R5), and data were analyzed using One-way ANOVA. Results showed that the experimental group achieved significantly greater improvements in psychological skills than the control group (p < 0.000). Beyond enhancing mental readiness for competition, the program fostered social skills, team solidarity, and community engagement. These findings suggest that football-based psychological skills training can strengthen both individual resilience and social inclusion in border regions. Further research is recommended to assess the long-term effects and applicability of this approach to diverse populations.

Understanding Teachers’ Knowledge of Meaningful Physical Education in Community of Practice Contexts: A Cross-Sectional Comparative Study

Hilda Ilmawati — 2026-04-26

Study purpose. Teachers' understanding of Meaningful Physical Education (Meaningful PE) is a key aspect in promoting meaningful learning experiences for students. While various professional development programs, such as Communities of Practice (CoP), have been implemented, empirical evidence regarding teachers' understanding based on professional characteristics remains limited. This study aims to analyze physical education teachers' level of understanding of Meaningful PE and examine differences based on gender and years of teaching experience.

Materials and methods. The study used a quantitative survey design with a cross-sectional approach towards 66 physical education teachers who regularly participated in CoP. The instrument used was a Likert scale questionnaire (1–5) consisting of 16 statements related to conceptual understanding of Meaningful PE, which had an r = 0.873. The data were analyzed using the One-Way ANOVA test and the Tukey test.

Results. The findings indicate that gender is not a significant differentiating factor in teachers' knowledge levels, whilst teaching experience contributes significantly to variations in knowledge. These results confirm that professional experience and involvement in collaborative learning communities play a greater role in shaping teachers' pedagogical literacy than demographic characteristics.

Conclusions. This study reinforces the urgency of community-based continuing professional development to improve teachers' conceptual understanding of meaningful physical education pedagogy.

The Effect of Box Jumping and Barrier Jumping Exercises on Jump Height

Muhammad Zen Almunawar — 2026-04-28

Study purpose. This study was conducted in response to insufficient lower leg muscle explosiveness observed in volleyball extracurricular students at State High School 1 Madang Suku III, which adversely affected their jumping performance during gameplay.

Materials and methods. A quantitative experimental approach was employed using a two-group pretest–posttest design. Statistical analyses were performed using paired-sample t-tests to examine within-group differences and independent-sample t-tests to compare the effects between groups.

Results. The findings revealed that the Jump to Box training method significantly enhanced lower limb muscle explosive power (t = 56.564, p < 0.05). Likewise, the Barrier Hops training method demonstrated a statistically significant improvement (t = 59.088, p < 0.05). However, the results of the independent-sample t-test indicated no statistically significant difference in effectiveness between the two training interventions (p = 0.704).

Conclusions. These findings suggest that both Jump to Box and Barrier Hops exercises are equally effective in improving lower limb explosive power among volleyball extracurricular participants.

The Biomechanical Analysis of Sepak Takraw Smash Technique Using Video-Based Motion Analysis

Dadang Budi Hermawan — 2026-04-28

Study Purpose. The smash technique is one of the most important offensive skills in sepak takraw and plays a decisive role in scoring points. Effective smash execution requires optimal coordination of the lower limbs and trunk, which can be examined through biomechanical analysis. This study aimed to analyse the biomechanical characteristics of the sepak takraw smash technique using video-based motion analysis.

Material and Methods. This study employed a descriptive quantitative research design. The participants were 15 male students from the Physical Education, Health, and Recreation (PJKR) study program, aged 18–22 years, who actively participated in sepak takraw training. Smash movements were recorded with a smartphone camera that supports slow motion. Video-based motion analysis software was used to measure biomechanical variables, including knee, hip, and ankle joint angles; kicking-leg swing velocity; ball contact height; and trunk inclination angle. Descriptive statistics were used to calculate means and standard deviations for each variable.

Result. The results showed that participants performed the smash technique with a mean knee angle of 158.4° ± 5.2° and a hip angle of 142.1° ± 6.3° at the moment of ball contact. The kicking-leg swing velocity reached an average of 18.6 ± 2.4 m/s, while the ball contact height was recorded at a mean of 2.15 ± 0.12 meters. Additionally, the trunk inclination angle showed an average of 12.5° ± 3.1°, demonstrating a forward body posture that contributes to balance.

Conclusion. Video-based motion analysis is an effective and practical method for evaluating the biomechanical characteristics of the sepak takraw smash technique. The findings provide useful information for coaches to improve smash performance and develop training programs based on biomechanical principles.
