Abstract

This study aims to predict adolescents' mood based on physical activity patterns using machine learningalgorithms. Physical activity is often closely correlated with emotional states, making this approachpotentially valuable in providing new insights to support mental health. Data were collected from 50university students using wearable devices over 90 days, including parameters such as step count, activityduration, intensity, and sleep patterns. Mood data were obtained using the BRUMs scale, which had beenadapted and validated. Decision Tree and Support Vector Machine (SVM) algorithms were employed todevelop the predictive model, with performance evaluated based on accuracy, precision, recall, and F1-scoremetrics. The results showed that the Decision Tree outperformed SVM, achieving an accuracy of 98.44%compared to 97.45%. Decision Tree also demonstrated advantages in model interpretability andcomputational efficiency, which are crucial for implementing real-time predictive applications. This studyconcludes that the Decision Tree algorithm is a more effective approach for mood prediction based onphysical activity patterns in adolescents. These findings are expected to form the foundation for developingmental health support systems based on wearable technology.

Abstract

Population aging in Indonesia demands scalable programs that elevate everyday functioning and well-being. This study evaluated an integrated nutrition and physical activity program grounded in Social Cognitive Theory for community-dwelling older adults. Using a quasi-experimental, community-based design, the intervention combined nutrition education with cooking practice, progressive exercise, self-efficacy-oriented counselling, and peer support, and was assessed with validated measures of quality of life, nutritional status, and physical activity. Participants receiving the program achieved marked improvements across all outcomes relative to comparison participants, and gains persisted beyond the intervention period. These benefits arose because the program simultaneously strengthened capability through skills and knowledge, opportunity through social support and access, and motivation through enhanced self-efficacy, goal setting, and self-monitoring. Hands-on practice and vicarious learning built mastery, while culturally adapted materials and peer leaders reduced barriers and reinforced adherence. Findings indicate that a theory-driven, multi-component approach is feasible within primary care and can advance healthy aging and equity in Indonesian communities.

Abstract

This study aims to determine the relationship between sleep disturbances and mood swings in sports students. Sleep disturbances are known to affect cognitive function, physical performance, and an individual's psychological state, particularly in adolescents undergoing developmental transitions. The study employed a quantitative approach with a cross-sectional design, involving 50 students majoring in Sports Science at the Indonesian University of Education, consisting of 27 males and 23 females aged 19–20 years. The instruments used included the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and the Brunel Mood Scale (BRUMS) to assess mood. Data analysis was performed using a correlation test using SPSS version 26. The results showed that the majority of respondents experienced negative moods (78.6%), with tension and fatigue items being the most dominant. However, no significant relationship was found between sleep quality and mood swings (p > 0.05). This finding indicates that other factors such as lifestyle, academic stress, and social environment have the potential to have a greater influence on the mood of sports students. Further research with a larger sample size is recommended to deepen the understanding of the relationship between sleep disturbances and students' psychological state.

Abstract

This study tried to probe possible differences in mental toughness between female musicians and female athletes as an approach toward better understanding the concept of psychological resilience across different performance contexts. The sample population consisted of sixty females from Universitas Pendidikan Indonesia: thirty athletes coming from the Faculty of Sports and Health Education (Faculty of Sports and Health Education) and another group of thirty musicians belonging to the Faculty of Art and Design Education (FPSD). Data were collected through the use of the Mental Toughness Questionnaire 18 (MTQ18) which duly described emotional control, self-belief, motivation, confidence, and challenge. Above all other specific requisites, this instrument rated high with excellent construct and content validity in earlier studies. A descriptive comparison analysis showed that musicians were less mentally tough overall (M = 58.80, SD = 3.68) than athletes (M = 64.50, SD = 5.24). It is in the motivation and emotional control components where the widest gaps are seen-with higher internal drive and better emotional regulation among athletes. Much more slightly tilted toward the athlete’s side, the ratings of challenge between the two groups were almost identical. Results of this study support a claim that performing arts environments develop less psychological flexibility compared to controlled competitive sports environments because artistic domains emphasize creativity and expression. This study enhances understanding of the psychological rigidity of women and at the same time helps offset the gender bias that has informed past studies. Practical ramifications include the development of domain-specific mental training programs, for example, goal-setting and stress management training for athletes as well as emotional control techniques for musicians which can be derived from this study. Limitations include a small sample size based on self-reported data without subgroup analysis. More comprehensive studies with larger samples composed of different groups are required in addition to long-term studies to trace the development of mental toughness in various fields of performance.

Abstract

The post-pandemic era has transformed athletes’ training habits, with social media emerging as a vital medium that supports independent training among student athletes. Despite its growing use, limited studies have examined its post-pandemic impact. This study aims to explore how social media contributes to athletes’ motivation, consistency, and independence in training when traditional facilities have resumed. Method: Using a qualitative design, eight student athletes were purposively selected. Data were collected through in-depth interviews and analyzed using the Miles and Huberman interactive model to identify key themes. Findings reveal that social media platforms such as Instagram, TikTok, and YouTube serve as alternative learning spaces for technical, physical, and mental training. They enhance flexibility, motivation, and engagement. Social media significantly supports self-directed learning and motivation, complementing conventional training methods while fostering independence, discipline, and innovation among student athletes in the post-COVID-19 context .
