Abstract

Research Problems: Basketball is a high-intensity sport that demands physical endurance, including strength, agility, endurance, speed, flexibility, balance, and explosive muscle power, while combining technical skills, tactical intelligence, and mental toughness. Increased leg muscle mass is directly proportional to strength and explosive power, which play an important role in jumping and shooting success. Research Objectives: This study aims to examine the relationship between leg muscle mass and leg muscle explosive power with jump height in basketball athletes, and the results can serve as a reference for coaches in designing more varied and effective training programs to improve overall team performance. Methods: This study uses a quantitative approach and correlation tests on 21 UNESA student league athletes, comprising 11 men and 10 women. Leg muscle mass instruments were taken using the Onpoint tool, while data on leg muscle explosive power and jump height were obtained using the Forcedecks tool. Results: The results of this study concluded that the three variables showed significant results, with data on left leg muscle mass (r=0.728; p=0.001) and right leg muscle mass (r=0.712; p=0.001) with jump height and data on leg muscle explosive power with jump height (r=0.813; p=0.001). Conclusion: these findings prove that increasing leg muscle mass and leg muscle explosive power contribute significantly to the vertical jump ability of basketball athletes, with leg muscle explosive power being the dominant factor in determining jump height.

Abstract

Research Objectives: Children's sports programs have increasingly garnered attention from the government and society in recent years, particularly recreational sports like pushbike, which have become increasingly popular among children. Creating a supportive environment where parents can balance motivation with proper understanding is crucial to helping children effectively internalize the drive to engage in sports. Research Objectives: This study aims to analyze the intrinsic and extrinsic motivation of parents in enrolling their children in the Academy Pushbike Jatim Pro. Methods: The method used was quantitative descriptive with a questionnaire containing 43 items distributed to 25 parent respondents. The data were analyzed descriptively using percentages to categorize motivation levels and were also presented in frequency diagrams for each category. Results: The results of the study indicate that parents' intrinsic motivation is more dominant in the high (32%) and very high (24%) categories, while extrinsic motivation is more prevalent in the low (44%) and very low (24%) categories. Overall, 32% of parents' motivation falls into the high category. Conclusion: These findings indicate the need for continuous evaluation and monitoring to develop young athletes with balanced intrinsic and extrinsic motivation. Additionally, further research is recommended to explore children's motivation directly, thereby providing a more comprehensive understanding of the factors influencing children's sports performance.

Abstract

Background: Professional teachers are required to have good physical and mental health. The hope is that professional teachers can carry out their daily tasks without experiencing significant fatigue. To determine changes in physical activity and mental health before and during the practice of field experiences. Methods: This research uses a quantitative approach with survey methods. The population that is the subject of the study is Pre-service PPG students of Surabaya State University (Unesa) in 2023. The instruments used involved the General Physical Activity Questionnaire (GPAQ) to assess the level of physical activity and the General Health Questionnaire (GHQ) to evaluate the level of mental health of respondents. Results: The study highlights the need to balance physical and mental health among Pre-service PPG students during field experiences. Conclusions: While physical activity increased, it wasn't statistically significant. However, slight rises in psychological distress suggest potential shifts in mental well-being, urging educational institutions to address these aspects for improved teacher education quality.

Abstract

Background: As older adults age, they experience a decrease in muscle mass and strength (sarcopenia), which increases the risk of falls and impacts morbidity, mortality, and quality of life. However, evidence on the relationship between handgrip strength and balance, as measured using the timed up and go test, in community-dwelling older adults is still limited, particularly in Indonesia. Thus, the purpose of this study is to examine the relationship between handgrip strength and balance in older adults. Methods: This study used a cross-sectional study design. The sample size in this study was 35 female individuals who met the inclusion and exclusion criteria. The handgrip strength test used a handgrip dynamometer. Meanwhile, the balance test was measured with a time up and go test. Data normality analysis used the Shapiro Wilk test method (p-value > 0.05), and Pearson correlation to analyze the relationship between two variables (p-value < 0.05). Results: There was a significant negative correlation between the average right HGS (16.63 kg) and TUG (p-value 0.001 and r-value -0.600) and the average left HGS (15.39 kg) and TUG (p-value 0.002 and r-value -0.513). Conclusions: :  This study shows that dominant handgrip strength in community-dwelling older women is significantly correlated with balance and mobility. These findings expand the evidence in Indonesia that dominant handgrip strength has the potential to be used as an early screening indicator for functional mobility in older adults.

Abstract

The purpose of this study was to analyze the effect of sports massage manipulation which is often used as passive recovery by measuring pain intensity using a visual analog scale (VAS) after eccentric exercise. This type of research is quantitative, with a quantitative descriptive design using a questionnaire (VAS), and data analysis method from examining pain intensity before and after manipulation of massage therapy. 54 athletes at the Indonesian National Sports Committee (KONI) in the Sidoarjo district participated as subjects. Using the Descriptive Statistical test before and after the massage therapy manipulation was carried out using the table or graphic diagram method, and the data obtained would be processed using SPSS for Windows v.22. It shows the mean (average) results of respondents' answers from respondents' answers about perceived pain intensity. From the results of testing the normal distribution of data using the Kolmogorov-Smirnov normality test, and then using the Wilcoxon test and the result was that there was a difference between pre and post-giving sport massage after eccentric exercise on pain intensity. From this study, it was concluded that giving sports massages had an effect on reducing pain intensity after eccentric exercise
