Abstract

This study aimed to examine the direct and indirect effects of nutritional status, parenting styles, and self-confidence on the motor skills of elementary school karate participants. A quantitative cross-sectional design was employed involving 59 male karate participants aged 9–11 years selected through purposive sampling. Nutritional status was assessed using body mass index, while parenting styles, self-confidence, and motor skills were measured using validated questionnaires and the Scott Motor Ability Test. Data were analyzed using path analysis after normality and linearity assumptions were confirmed. Nutritional status, parenting styles, and self-confidence significantly affected motor skills both directly and indirectly (p < 0.05). Parenting styles showed the strongest direct effect (37.09%), followed by nutritional status (33.52%) and self-confidence (27.56%). The structural model explained 72.3% of the variance in motor skills. Motor skills among elementary school karate participants are jointly influenced by biological, family, and psychological factors, highlighting the importance of integrating nutritional improvement, supportive parenting, and confidence-building strategies to optimize children's motor development.

Abstract

This study aims to comprehensively examine the difference in playing satisfaction between synthetic carpet courts (vinyl/PVC) and cement floor courts (concrete) among badminton players, while also analyzing the underlying biomechanical implications. This quantitative study, using an ex-post facto approach, involved 150 badminton players (98 men, 52 women, aged 18-35 years). The results of the Paired Sample t-Test showed a statistically highly significant difference (t = 24.83; p = 0.000 < 0.05). The mean playing satisfaction score on synthetic carpet courts (M = 4.32; SD = 0.45) was significantly higher than on cement floor courts (M = 2.85; SD = 0.58). Shock absorption and pain prevention emerged as the largest contributors to the higher satisfaction level on carpet courts. These findings indicate the need for a gradual conversion of badminton court surfaces from cement floors to BWF-standard synthetic carpet to improve playing comfort and reduce players' risk of biomechanical injury.

Abstract

Technical competence is essential for long-term athlete development in badminton; however, the development of racket skills and court-movement abilities during the novice stage remains insufficiently examined. This study aimed to describe serve, net-drop, and smash accuracy, as well as footwork agility, and to examine their relationships with chronological age and sex. A descriptive quantitative, cross-sectional design was employed involving 23 novice athletes (16 boys and 7 girls) aged 11–15 years from a university-affiliated badminton academy in West Sumatra, Indonesia. Participants completed a standardized field-test battery consisting of a modified French-Scott-Fox serve accuracy test, net-drop and smash accuracy tests, and an 8-point footwork agility test. Data were analyzed using descriptive statistics, norm-referenced scoring, Spearman’s rank correlation, and the Mann–Whitney U test. Mean serve accuracy was 45.4% (SD = 22.3), while net-drop and smash accuracy scores were 21.52 (SD = 8.55) and 18.74 (SD = 9.66), respectively. Mean footwork time was 18.14 s (SD = 3.33), with 69.6% of athletes classified in the very slowest normative category. Racket skills demonstrated moderate-to-high intercorrelations (ρ = 0.60–0.69, p < 0.01), whereas footwork was significantly correlated only with smash accuracy (ρ = −0.49, p = 0.018). Boys outperformed girls across the four performance measures (p = 0.006–0.007; d = 1.10–1.19), despite no significant difference in age distribution (p = 0.397). Age showed moderate-to-strong associations with the measured skills (|r| = 0.47–0.57, p < 0.03). These findings indicate that racket-handling and locomotor skills represent relatively distinct domains of early technical development. Therefore, novice training programmes should place greater emphasis on footwork and multidirectional agility while considering age- and sex-related differences when grouping athletes for training.

Abstract

Regular participation in physical activity is essential for adolescents' physical and psychological well-being. However, students often demonstrate varying levels of participation in school-based physical education programs due to differences in motivation and personal interest. This study examined the relationship between student interest and discipline in participating in the Senam PAHAMI morning exercise program at SMKN 4 Padang, Indonesia. Drawing on Self-Determination Theory and Expectancy-Value Theory, the study hypothesized that higher levels of student interest would be associated with greater discipline. A quantitative correlational research design was employed involving 427 Grade X and XI students, representing the entire eligible population through a census approach. Data were collected using Likert-scale questionnaires measuring student interest and discipline. The instruments demonstrated good internal consistency, with Cronbach's alpha coefficients of 0.82 and 0.85, respectively. Data were analyzed using the Kolmogorov–Smirnov normality test, Pearson product-moment correlation, and the coefficient of determination. The findings indicated moderately high levels of both interest (M = 57.70, SD = 4.62) and discipline (M = 69.33, SD = 5.49). A statistically significant positive correlation was found between student interest and discipline (r = 0.413, p < 0.001). The coefficient of determination showed that student interest explained 17.02% of the variance in discipline, while the remaining variance may be attributed to factors such as teacher supervision, school culture, peer influence, and individual characteristics. These findings support Self-Determination Theory and Expectancy-Value Theory, emphasizing that fostering students' intrinsic interest can enhance discipline in school physical activity programs. The results provide practical implications for physical education teachers and school administrators in promoting student engagement and participation.
