Abstract

Background: Injuries are a risk in sports that affect athletes not only physically but also psychologically, such as through anxiety and motivation. The research problem is the lack of clarity regarding the impact of injury history on the psychological aspects of student athletes. Objectives: This study aims to determine the effect of injury history on anxiety and motivation among student athletes in West Java. Method: The study employed a quantitative approach using simple linear regression analysis on 42 athletes selected through purposive sampling. The instruments included an injury history questionnaire, the General Anxiety Disorder-7, and the Sport Motivation Scale. Result: The results showed that injury history did not have a significant effect on anxiety (Sig. = 0.219), but had a near-significant relationship with motivation (Sig. = 0.055), indicating a tendency toward increased motivation. Conclusion: The conclusion indicates that injury history does not significantly affect anxiety and only shows a tendency toward motivation; therefore, it cannot be concluded as a statistically significant relationship. These findings underscore the importance of an evidence-based holistic approach in athlete training and recovery.

Abstract

Background: Physical literacy (PL) is recognized as a fundamental concept for encouraging children to engage in lifelong physical activity and achieve healthy outcomes. However, in Indonesia, normative data and interpretive criteria for assessing children’s physical literacy are lacking. The Physical Literacy in Children Questionnaire (PL-C Quest) is a validated pictorial self-report tool, but no interpretation guidelines exist for its use in Indonesian contexts. Objectives: This study aimed to establish baseline normative data and preliminary interpretive guidelines for the PL-C Quest in Indonesian children aged 6–8 years. Method: A cross-sectional descriptive study was conducted with 50 children (19 boys, 31 girls) aged 6–8 years, recruited from Indonesian elementary schools. Each child completed the 30-item PL-C Quest, which uses cartoon illustrations to assess perceived physical literacy across four domains (Physical, Psychological, Social, Cognitive). Descriptive statistics (means, standard deviations, ranges, percentiles) were calculated for total and domain scores. Preliminary percentile-based categories were developed to interpret individual scores. Result: The mean overall PL-C Quest score was 90.22 ± 11.74 (out of 120; ~75.2% of the maximum), with a median of 92 and range of 59–112. Domain scores (as percentages of their maximums) were highest in the social domain (79.3%), followed by Physical (77.0%), Psychological (72.4%), and Cognitive (71.6%). Five interpretive categories were defined: Very High, ≥102 points, High, 97–102, Moderate, 80–97, Low, 71–80, and Very Low, ≤71. Boys scored marginally higher on average than girls (91.53 vs. 89.42), and scores showed a slight decline with increasing age (mean for 6-year-olds 98.67; 7-year-olds 90.84; 8-year-olds 87.20). Conclusion: This study provides the first normative data on physical literacy for Indonesian children, revealing generally high perceived physical literacy with strengths in social interaction and physical competence. Areas for improvement include the cognitive and psychological domains. The new percentile-based categories offer educators and practitioners practical benchmarks for interpreting PL-C Quest scores and identifying children who may benefit from targeted interventions. These findings supply a crucial baseline for developing physical literacy programs and future research in Indonesia.

Abstract

Background: Physical activity is one of the most important factors in maintaining physical fitness and mental health among students. Sometimes motivation to exercise declines over time among final-year students due to academic responsibilities, focus on completing final assignments, and a new orientation focused on preparing for the world of work. This situation is one of the factors causing a decline in motivation to exercise. Although recent studies have examined the motivation to exercise in the general population, specific studies examining the motivation to exercise among final-year university students are still very limited. In researching their exercise motivation profiles, it is essential to support a sustainable active lifestyle in their college environment. Objectives: This study aims to examine the regulation of exercise motivation among final-year university students based on the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) and to investigate the most dominant form of motivation regulation that influences their participation in exercise. Method: This study used a quantitative descriptive design with 35 final-year active students selected through purposive sampling. The BREQ-2 instrument, consisting of 19 items across five motivational dimensions, was administered online. The collected data was analyzed using descriptive statistics to obtain the mean value, minimum value, maximum value, standard deviation, and percentage distribution for each dimension. Result: The findings of this study show low scores of amotivation (M= 2.43) and external regulation (M= 3.46), indicating indifference and minimal influence from external pressures. Introjected regulations was in moderate category (M= 6.40), reflecting a sense of self-imposed obligation. Identified regulation (M= 12.14) and intrinsic motivation (M+ 13.66) scored the highest, indicating that students engage in exercise based on personal value and enjoyement. Conclusion: Overall, the results of the study show a motivation profile dominated by things that arise from and are enjoyed by themselves, especially in identified regulation and intrinsic motivation. However, motivation levels tend to be moderate based on the distribution of scores. The results of this study emphasize the importance of campus efforts in improving opportunities for better and more flexible exercise in order to strengthen sustained participation in sports among final-year students. This study contributes by examining more specific group, namely final-years  students, which has not been previously explored in detail or with a specific focus.

Abstract

Background: cardiovascular and respiratory fitness (CRF) is a critical health indicator linked to students metabolic well being and funcional capacity to perform physical activities. Despite its importance, empirical evidence regarding the distribution of maximum oxygen consumption (VO2MAX), particularly among vocational high school students, remains limited. Objectives: the purpose of this study is to analyze the descriptive statistical profile and categorical distribution of vo2max among students at smk bina nusantara ungaran, grouped by age and biological sex. Method: this study employed a quantitative descriptive design involving 298 students (223 males and 75 famales). Vo2max was measured using the 1.6km rockport walk test, and the data were analyzed using descriptive statistics, including mean, standard deviation, and frequency distribution. Result: the resuts of the study showed that male students achived an average vo2max value of 35.02 ± 5.07 ml/kg/min, while female students showed a lower average value of 27.35 ± 3.10 ml/kg/min. Specifically, categorical analysis revealed a significant fitness gap, with 32.73% of male students and 70.66% of female students falling into the into the poor and very poor categories. Conclusion: in conclusion, the majority of students, particularly female students, exhibit suboptimal levels of cardiovascular and respiratory fitness, wjich may affect their readines to enter the workforce in the future. These findings underscore the urgent need for gender inclosive physical activity interventions and policy adjustments in vocational education to improve long term health and industrial productivity.

Abstract

Background: Pencak silat is a competitive martial art originating from Indonesia that relies not only on physical strength and technique but also requires intense focus and concentration. Athletes often face immense pressure, and an inability to control their emotions can lead to a decrease in their performance. Objectives: This study aims to empirically analyze the relationship between cognitive anxiety and somatic anxiety and self-confidence among athletes in the UKM Perisai Diri UPI, particularly those facing the “double burden” of academic and athletic demands. Method: This study employed a quantitative, descriptive-correlational design; data were collected using the CSAI-2R questionnaire. Given that the data distribution was not normal (P < 0.05), Spearman’s rank correlation ( s) was used as the primary analysis. Result: The results showed a very strong and significant negative correlation, including cognitive anxiety and athlete self-confidence ( s = -0.938;  < 0.01), somatic anxiety and self-confidence ( s = -0.882;  < 0.01). In addition, as many as 63.4% of athletes had high self-confidence, 53.3% managed to control mental anxiety. However, simultaneously, the remaining 26.7% experienced high levels of somatic anxiety (average score 26.17). Conclusion: The strong and significant correlation between the level of anxiety and self-confidence among UPI Perisai Diri UKM athletes indicates that the mental condition of the athletes is very sensitive to competitive stress, even though they have a high level of self-confidence.
