Risky Sandy Kurniawan1, Donny Anhar Fahmi2, Setiyawan Setiyawan31. Universitas PGRI Semarang , ID2. Universitas PGRI Semarang , ID3. Universitas PGRI Semarang , ID2025-08-15|page 212-221AbstractBackground: Futsal is a high-intensity sport that requires leg muscle power, especially in aerial duels, anticipating the ball, and performing powerful kicks. Limited jumping ability can reduce leg muscle power and overall performance.
Objectives: This study aims to test the impact of plyometric training using step-up and lateral box jumps on the improvement of leg muscle power in youth school futsal athletes.
Methods: A quasi-experimental single-group pretest-posttest design was conducted with 40 male participants over a four-week plyometric training program. Leg muscle power was measured using a vertical jump test before and after the intervention. Data were analyzed using a t-test with the assistance of SPSS.
Results: Both step-up and lateral box jumps significantly increased leg muscle power (p < 0.05). The step-up group showed an average increase of 4.20 cm, while the lateral box jump group showed an average increase of 3.45 cm, with no statistically significant difference (p = 0.326).
Conclusions: Both training methods effectively enhance leg muscle power and can be integrated into school-based futsal training programs to improve performance.

Associations of lower limb muscle strength and body reaction time with crescent kick performance in competitive pencak silat athletes
Jery Setiawan1, Siti Baitul Mukarromah21. State University of Semarang , ID2. State University of Semarang , ID2026-08-17|page 208-219AbstractBackground: Crescent kick performance is an important technical component of competitive pencak silat and may be associated with physical capacities such as lower limb muscle strength and reaction time. However, evidence regarding the relationships of these physical characteristics with crescent kick performance remains limited.
Objectives: This study aimed to examine the associations of lower limb muscle strength and body reaction time with crescent kick performance among competitive pencak silat athletes.
Methods: This quantitative correlational study involved 30 competitive pencak silat athletes (age: 19.8 ± 2.1 years; height: 168.4 ± 6.3 cm; body mass: 61.7 ± 8.2 kg; body mass index: 21.7 ± 2.3 kg/m²) recruited using total sampling. Lower limb muscle strength was assessed using a leg dynamometer, body reaction time using a reaction timer, and crescent kick performance using a 10-second crescent kick test. Data were analyzed using descriptive statistics, Pearson correlation, and multiple correlation analysis, with statistical significance set at p < .05.
Results: Lower limb muscle strength was positively associated with crescent kick performance (r = 0.734, p < .001), whereas body reaction time was negatively associated with crescent kick performance (r = -0.739, p < .001), indicating that shorter reaction times were associated with better kick performance. Multiple correlation analysis showed a strong combined association of lower limb muscle strength and body reaction time with crescent kick performance (R = 0.754, R² = 0.568, p < .001). Together, these variables accounted for 56.8% of the variance in crescent kick performance.
Conclusions: Greater lower limb muscle strength and shorter body reaction time were associated with better crescent kick performance among competitive pencak silat athletes. These findings highlight the relevance of muscular strength and neuromuscular responsiveness to crescent kick performance and may inform physical conditioning programs for pencak silat athletes. Further studies with larger samples and additional biomechanical, physiological, and technical measures are needed to better understand the factors associated with crescent kick performance.

Department of Sports Coaching Education, Faculty of Sport and Health Sciences, Universitas Negeri Surabaya , ID5. Department of Sports Coaching Education, Faculty of Sport and Health Sciences, Universitas Negeri Surabaya , ID2026-03-08|page 28-39AbstractBackground: Recognized globally as the fastest racket sport in the world, badminton demands exceptional acceleration and footwork skills for competitive success. However, many intermediate players often struggle to produce the explosive power needed for fast-paced rallies. To enhance these physical attributes, targeted training interventions, such as a hybrid regimen of plyometric and ladder drills, are often required.
Objectives: This study aims to analyze the efficacy of integrating plyometric exercises with ladder drills in enhancing acceleration and footwork proficiency among badminton players.
Methods: This research employed a quasi-experimental design with a non-equivalent control group. Through purposive sampling, 24 male participants (aged 14-16 years) with at least 2 years of training experience, good health, and no history of recent injuries were selected. They were assigned to either the PLD Group (age: 15.00 ± 0.74 years; height: 162.00 ± 0.07 cm; weight: 50.58 ± 5.68 kg; BMI: 19.20 ± 0.88 kg/m²) or the CV Group (age: 15.00 ± 0.85 years; height: 162.08 ± 0.08 cm; weight: 51.75 ± 8.05 kg; BMI: 19.59 ± 1.56 kg/m²). The intervention spanned six weeks, with three sessions per week. Performance in acceleration was assessed using a 10-meter sprint, and footwork skills were assessed using the footwork skills test (Tohar version) pre- and post-intervention. Data analysis employed the Wilcoxon signed-rank and the Mann-Whitney tests.
Results: The Wilcoxon analysis indicated that both the PLD and CV Groups achieved improvements in acceleration and footwork skills (p<0.05). However, the Mann-Whitney test revealed a statistically significant difference between the two groups, with the PLD Group demonstrating superior gains in both acceleration (p<0.05) and footwork skills (p<0.05) compared to the CV Group.
Conclusions: Integrating plyometric training and ladder drills is an effective strategy for significantly improving acceleration and footwork skills in badminton players.

Predictors of cardiorespiratory endurance in martial arts athletes: A path analysis of body composition, hemoglobin, and motivation
Novanto Ponco Nugroho 1, Dani Nur Riyadi2, Aridhotul Haqiyah31. Universitas Islam 45 Bekasi , ID2. Universitas Islam 45 Bekasi , ID3. Universitas Islam 45 Bekasi , ID2025-07-01|page 83-94AbstractBackground: Cardiorespiratory endurance is vital to athletic performance, particularly in sports requiring sustained physical exertion such as martial arts.
Objectives: This study examined the predictive roles of body composition (BMI), hemoglobin concentration, and motivation on cardiorespiratory endurance among university-level martial arts athletes.
Methods: Using a quantitative path analysis design, data were collected from 20 purposively selected martial arts athletes who regularly trained. Cardiorespiratory endurance was assessed via the multistage fitness test, BMI was calculated using standard anthropometric measures, hemoglobin was measured using the Harenz scale, and motivation was evaluated with a validated Likert-scale questionnaire.
Results: The analysis showed that BMI (ρ = 0.705, t = 3.071, p = 0.007) and hemoglobin concentration (ρ = 0.946, t = 4.672, p < 0.001) had significant positive effects on cardiorespiratory endurance. Motivation, however, did not have a significant direct effect (ρ = 0.087, t = 0.853, p = 0.203). Additionally, BMI correlated positively with both hemoglobin (ρ = 0.923, p < 0.001) and motivation (ρ = 0.670, p = 0.034), suggesting indirect effects through physiological mechanisms.
Conclusions: The findings underscore that physiological indicators, specifically BMI and hemoglobin, are more critical predictors of aerobic capacity than psychological factors like motivation in this athletic population. Due to sport-specific demands, these results may not be generalizable to non-martial arts athletes. Future studies should incorporate additional mediators such as training intensity and account for potential self-report bias in motivation assessments.
