Abstract

The 24-Hour Movement Guidelines integrate physical activity, screen time, and sleep as interrelated behaviors that influence children’s health and academic outcomes. However, evidence from Indonesian primary school populations remains limited. This study aimed to examine adherence to the 24-Hour Movement Guidelines and to analyze its associations with body mass index (BMI) and academic performance among primary school children in Jambi City. A cross-sectional study was conducted involving 325 students (mean age 9.79 ± 0.90 years). Physical activity was assessed using the PAQ-C, screen time through a sedentary behavior questionnaire, and sleep quality using the Pittsburgh Sleep Quality Index (PSQI). BMI was calculated from measured height and weight, and academic performance was obtained from school records. Data were analyzed using descriptive statistics, Chi-square tests, Pearson correlation, and multiple linear regression. Overall adherence to all guideline components was low. Regression analysis showed that physical activity was negatively associated with BMI (B = –0.027, p = 0.006), while screen time (B = 0.056, p = 0.016) and sleep quality score (B = 0.041, p < 0.001) were positively associated with BMI. In relation to academic performance, sleep quality showed a positive association (B = 0.079, p < 0.001), followed by screen time (B = 0.107, p = 0.039), whereas physical activity showed a negative association (B = –0.066, p = 0.002). The results demonstrate that each component of movement behavior exhibits distinct statistical associations with BMI and academic performance among primary school children, without implying causal relationships due to the cross-sectional design.

Abstract

This study aimed to describe the kinematic characteristics of front kick speed in regional level Pencak Silat athletes from South Lampung Regency preparing for the 10th Lampung Provincial Sports Week (PORPROV X) in 2026. A quantitative descriptive approach was employed involving ten athletes (six males and four females) who were actively participating in a centralized training program. Front kick performance was recorded using a high-speed Fujifilm X-T4 camera at 240 frames per second with a 50 mm focal length lens to minimize perspective distortion. The recorded videos were analyzed using Kinovea 2025.1.1 software through two-dimensional kinematic analysis. The measured variables included kick displacement, execution time, and average kick speed. The results showed that male athletes achieved higher average front kick speeds (2.75 m/s) than female athletes (2.33 m/s), primarily due to shorter execution times rather than greater displacement. Overall, performance was characterized by adequate movement range but lower temporal efficiency compared to values reported in elite athletes, indicating that execution time is a key determinant of front kick speed at the regional level. This study contributes to the biomechanics of Pencak Silat by providing empirical kinematic data at the provincial level and identifying execution time as a primary performance-limiting factor. These findings offer a biomechanical basis for targeted training interventions focusing on neuromuscular coordination, explosive strength, and movement acceleration. It can be concluded that improving temporal efficiency is critical to enhancing front kick performance. Future studies should incorporate larger samples and three-dimensional analysis for a more comprehensive understanding.
