This qualitative study explores the role of pickleball in promoting healthy aging among elderly players in Indonesia. As the global elderly population continues to rise, the need for effective strategies to enhance physical, mental, and social well-being in older adults becomes more pressing. Pickleball, a low-impact sport that combines elements of tennis, badminton, and table tennis, has gained significant popularity worldwide due to its accessibility, moderate intensity, and low risk of injury. This study employed a phenomenological approach, conducting semi-structured interviews, participant observations, and focus group discussions with 19 elderly pickleball players aged 50 and above in Surabaya, Indonesia. The findings suggest that regular participation in pickleball leads to significant improvements in physical health, including enhanced strength, balance, flexibility, and cardiovascular endurance. The sport also has positive effects on mental well-being, helping to reduce stress, improve cognitive function, and provide a sense of purpose and accomplishment. Socially, pickleball fosters community engagement, reduces feelings of isolation, and strengthens intergenerational relationships, allowing older adults to connect with younger generations. However, barriers such as physical limitations, limited access to facilities, and unfavorable weather conditions hinder consistent participation. In conclusion, pickleball is a valuable and effective activity for promoting healthy aging by providing a holistic approach to improving the quality of life in older adults. Policymakers, healthcare providers, and community leaders are encouraged to invest in pickleball infrastructure, promote awareness, and support active aging initiatives to further enhance the well-being of elderly populations.

Introduction: In daily routines, especially in heavy weight lifting activities, grip strength is important. This study aims to investigate grip strength with muscle mass and fat mass in the arms. Methods: Cross-sectional study with the subjects of this study were 45 students (15 females and 30 males) with male characteristics (age 19.8±0.83, height 168±6.10, weight 64.7±11.5, BMI 22.9±3.82) while in women (age 20±0.78, height 159.3±4.43, weight 57.3±11.6, BMI 22.6±4.33). Spearman correlation from SPSS version 26 with a significance level of P-value < 0.05. Finding: Based on the data, there was no significant correlation between grip strength and muscle ma and arm fat mass. Then the muscle mass of the right side with (P-value: 0.079, r: 0.265) and the left side (P-value: 0.059, r: 0.284), while the mass of fat on the right side (P-value: 0.090, r-value -0.256) and the mass of fat on the left (P-value: 0.180, r-value: -0.204). Conclusion: This study proves that there is no correlation between grip strength and muscle mass or arm fat mass. 

The study conducted at the National Potential Young Athletes Training Center (SLOMPN) of Unesa provides a crucial perspective on the use of an Android-based match statistics application. The research aims to optimize athletes' potential through the Long Term Athlete Development (LTAD) approach, integrating knowledge of athlete development with the application of technology in training. The survey results from 5 coaches indicate that the application aids in planning training, understanding application features, and assessing athlete development with positively skewed average scores. However, there is room for improvement, especially in terms of comfort during matches and communication with athletes. Meanwhile, 18 athletes showed positive acceptance of the application by rating its ease of use and impact on performance enhancement highly. Nevertheless, there is a need for improvement in injury recovery features and data security. This study underscores the importance of continuous collaboration between application developers and users to enhance the effectiveness of technology in sports training.
