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

Performing exercise or physical activities for a long duration under the exposure of air pollution becomes an unhealthy combination and will increase the risks of the individual inhaling more pollutant. Studies that examine an individual performing physical activities regularly in two public sport centers with different levels of air pollution have not been extensively documented, therefore the purpose of this study is to evaluate effects of regular exercise on aerobic capacity, force vital capacity (FVC), and hematological profile among individuals in an environment with similar climatic characteristics but different concentrations of air pollution. This trial composed 15 males (age range from 16 to 18) from Bandung City, Indonesia. Two public sport centers with similar climatic conditions (temperature, and humidity), but different concentrations of air pollutants are selected. Participants performed exercises three times a week for three consecutive weeks at each research site, with a two-week break. Participants’ aerobic capacity, respiratory capacity, and blood sample are measured before and after they exercised at each site. The measured parameters in both sites are compared and analyzed. Aerobic capacity, FVC, and RBC after participants exrcised in the area with lower air pollution show higher value than exercised in the area with higher air pollution. Manwhile WBC is shown to be high after participants exercised in the area with higher air pollution. This happened because air pollution has effect to human physiological characteristics. This research shows that exercising at sport center with high air pollution had negative effect on hematology profile and could affect the development of aerobic and respiratory capacities. The limitations in this study are the unknown intensity when doing regular physical exercise so that in future studies it is recommended to determine whether the intensity will affect the variables in the research subject.

Abstract

Background Problem: Nutrition plays an important role in fitness, yet there is limited understanding of how non-sporting students, particularly nutrition students, manage their fitness. This study fills the gap by exploring the relationship between physical activity, dietary habits, and fitness in this group. Research Objective: This study aims to examine the fitness profile of female undergraduate nutrition students and explore the factors associated with fitness such as physical activity level (PAL), nutritional status, and diet. Methods: To answer the research objective, a cross-sectional design was conducted, involving 114 healthy female students, aged 18-20 years old. Respondents were selected by using proportional random sampling, which enabled equal representation of each class in the study. Exclusion criteria: students have chronic disease or condition affecting physical fitness. Physical fitness was assessed using the Harvard Step Test, PAL was measured via an online self-administered IPAQ, nutritional status was assessed using a body mass index (BMI) calculation, and dietary data (energy and iron intakes) was assessed using 2x24 non-consecutive food records. Chi-squares or Fisher Exact tests were done to analyse the association between physical fitness and other variables. Finding and Result: We found that almost all of our respondents were at poor levels of physical fitness. There was no significant association between physical fitness and other variables such as PAL, BMI, and diet. Conclusion: This research supported previous findings that college students in health majors have poor fitness. Future studies should explore additional factors such as physiological stress, sleep pattern, or socio-economic status that may impact the fitness level of health-major students.

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.
