Abstract

This study aims to analyze the influence of dietary patterns and sedentary lifestyle on the learning outcomes of tenth-grade students at SMAN 1 Driyorejo. The study employed a quantitative approach with a correlational research design to examine the relationships and effects among the variables. The sample consisted of 35 students from class X-11 selected through purposive sampling. Research instruments included questionnaires on dietary patterns, sedentary lifestyle behavior, and documentation of students’ academic achievement. The collected data were analyzed using instrument validity testing, descriptive statistical analysis, Pearson correlation analysis, t-test, and multiple linear regression analysis. The results indicate that dietary patterns have a positive and significant effect on students’ learning outcomes, while sedentary lifestyle shows a significant influence with a tendency to reduce academic performance. Furthermore, the regression analysis reveals that dietary patterns and sedentary lifestyle simultaneously contribute significantly to variations in students’ learning outcomes. These findings emphasize that balanced nutritional intake and adequate physical activity play an important role in supporting students’ concentration, learning stamina, and academic performance. Therefore, improving dietary habits and reducing sedentary behavior are essential strategies for enhancing students’ learning outcomes in the digital era.

Abstract

This study aims to conduct an in-depth bibliometric analysis of the evolution of scientific publication trends regarding the impact of social support on athlete performance. Unlike previous studies that were often partial to specific sports or age groups, this research examines literature holistically from the Scopus database without demographic specification limitations to obtain a comprehensive global overview. Using VOSviewer software, this study maps publication patterns, influential authors, top journals, and the intellectual structure linking social support with mental resilience and athlete achievement. The results show a significant surge in publications over the last decade, with the United States, the United Kingdom, and Australia as dominant contributing countries. Key findings identify that social support functions as a crucial multidimensional mechanism for athletes' emotional stability across various competitive levels. This study provides strategic insights for coaches and sports practitioners to integrate psychosocial interventions into team management and recommends future researchers expand data coverage beyond Scopus to bridge existing literature gaps.

Abstract

Background: Glucose availability affects athlete performance, while fatigue can decrease it. One way to prevent fatigue and maintain performance is by consuming high-carbohydrate drinks. This study aims to analyze the effect of date palm juice and sports drink energy gel x on glucose levels. Methods: This study used a three-period double-blind cross-over design in Hall B, Jakarta State University, involving 10 healthy KOP Hockey athletes from Jakarta State University. Each period, participants underwent a moderate-intensity match with glucose measurements at 0, 20, 40, and 45 minutes. Between periods were separated by a 7-day washout to see significant differences between treatments. Results: Both types of carbohydrate drinks had no significant difference in carbohydrate content. Differences were considered significant if the value (P < 0.05). In treatment groups I and II, there was a significant difference in glucose levels between the 20th and 40th minutes, and between the 20th and 45th minutes, with a P value = 0.001 in group I. Conclusion: Both administration of date palm juice (phoenix dactylifera) mixed with water, and sports drink energy gel x had a significant effect on increasing blood glucose levels in the Jakarta State University hockey team. Keywords: dates extract, sport drink energy gel, blood glucose

Abstract

In the sport of swimming speed is a benchmark when athletes compete. To increase speed, arm and leg muscle strength is required. Lack of power in the leg kick and arm stroke phase will reduce swimming speed. This study aims to determine the difference in the effect of Paddle Resisted Training with Fin Assisted Training on 50 m freestyle swimming speed. The method used in this research is experimental method. The population used in this study were all members of the AKKSA Swimming Club. The sample amounted to 10 people who were taken using purposive sampling technique. The instrument in this study used the 50m Freestyle Swimming Test. The data analysis technique used is the Paired Sample t-test and the Independent Sample t-test. The results of this study indicate that there is a significant effect of Paddle Resisted Training with Fin Assisted Training on 50 m freestyle swimming speed and there is no significant difference in effect between Paddle Resisted Training and Fin Assisted Training on 50 m freestyle swimming speed.

Abstract

This study examined the associations of physical activity, sleep quality, screen time, and peer support with physical fitness among fifth grade students at SD Negeri Klodangan. A quantitative correlational design with a cross sectional approach was employed. Participants were 28 fifth grade students (12 boys and 16 girls). Physical fitness was assessed using a test battery consisting of the 20 m PACER, 30 second curl up, 30 second push up, standing long jump, sit and reach, and the 10×5 shuttle run. Physical activity and screen time were collected through a weekly journal, sleep quality was measured using a questionnaire, and peer support was assessed using a rating scale. Data were analyzed using descriptive statistics, assumption tests, Pearson or Spearman correlation, and multiple linear regression. The results indicated that physical activity, sleep quality, screen time, and peer support were not significantly correlated with physical fitness (p > 0.05), with Spearman correlation coefficients ranging from −0.220 to 0.256. Multiple regression also showed no significant simultaneous effect (R² = 0.160; p = 0.384). In conclusion, variations in students’ physical fitness in this context may be influenced by other factors beyond the proposed model. Further research is recommended to consider nutritional status, structured exercise intensity, and students’ motivation for physical activity.
