  • Park golf is establishing itself as a daily sport that the silver generation can enjoy physically and cost-free. Accordingly, we have examined the impact of park golf participants' passionate participation behavior on sports immersion and sports performance. The subjects were 243 park golf participants, and SPSS 21.0 and AMOS 18.0 were used for data processing. In addition, frequency analysis, reliability, confirmatory factor analysis, and correlation analysis were conducted. Path analysis was performed using SEM, and mediating effects were analyzed using bootstrapping. First, regarding the relationship between passionate behavior and sports immersion, harmonious passion did not affect sports immersion, and obsessive passion had a positive effect. Second, passion had a positive effect on sports performance. Third, sports immersion had a positive effect on sports performance. Fourth, sports commitment played a partial mediating role in the relationship between passion and sports performance. Therefore, if the environment of the park golf course is improved so that passion does not decrease, exercise immersion and exercise performance will improve.

  • Purpose - Sports leadership is frequently used as a useful comparison for understanding traits like teamwork and motivation in the business world. Based on the results of numerous studies, this research provides a critical assessment of the current state of knowledge in sport leadership research using methodological advances from other disciplines such as business and economics Research design, Data, and methodology - This research selected the systematic review analysis as its research design. The review analysis is a minimal set of elements for reporting in reviews by evidence. The present author included numerical data with confidence ranges for the most crucial outcomes if the review contained meta-analyses. Result - According to a study in sports, transformational leadership has a positive effect on company success. Communication and commitment, two possible mediators, may strengthen the impact of transformational leadership on cohesiveness. Prior researchers found that intrinsic drive serves as a bridge between transformational leadership and performance. Conclusion - This research concludes that the articles used for data analysis in this study examined the value of sports leadership for business leaders in a number of sports, including athletics and handball, among others. There is a good chance that different sports will provide different insights on the value of sports leadership for CEOs.

  • [Purpose] Functional beverages are intended to support those who want to maintain optimal physical condition and improve their quality of life through the enhancement of heart health, immunity, and digestion. The purpose of this study was to investigate the performance of top-level athletes consuming immune-strengthening conditioning nutritional drinks. [Methods] A total of 107 top-level athletes (baseball (56 players), pro volleyball (17), athletics (16), cycling (8), golf (6), and fencing (6)) participated in the experiment. They consumed an immune-enhancing functional beverage once a day for 8 weeks and responded to a survey before, during, and after drinking the beverage. [Results] Three total aspect-based subfactors were drawn from 24 questions in the factor analysis: physical, satisfaction with mental stability, and activity in performance. The physical, mental stability and performance changes of athletes significantly increased in period 2 (4 weeks after intake) and period 3 (after 8 weeks of intake). [Conclusion] We evaluated the efficacy of a new conditioned beverage containing Lactobacillus B240 and protein in improving the performance and physiological utility of top athletes. This functional drink may gain popularity among those seeking health benefits and improved exercise performance.

  • This study investigates the bending and stability properties of cylindrical constructions, with a focus on their use in the design and implementation of sporting equipment. The work focuses on a cylindrical construction resembling nanomotors, similar to components seen in sports equipment, using mathematical modeling based on high-order beam theory and nonlocal strain gradient theory. The analysis provides important insights into the dynamic behavior of these systems, revealing light on the impact of numerous factors such as rotational velocity, section change rate, and structural dimensions. The results show a relationship between angular velocity growth and section change rate, which leads to an increase in fundamental frequency values. Furthermore, the research emphasizes the effect of structural factors on dynamic deflection, giving critical information for increasing the stability and performance of sporting equipment. This study adds to the area of sports engineering by providing a more nuanced understanding of how cylindrical constructions react under diverse settings. The results will help to guide the design and manufacturing processes of sports equipment, assuring improved stability and performance for players across a wide range of sports.

  • This study aimed to identify the effects of sports participation motives, the involvement in choosing sportswear, and the satisfaction with/perceived importance of sportswear functionality, on customers' repurchase intentions. A total of 185 survey questionnaires were analyzed after surveying 200 female undergraduates in their 20s. The research results are as follows. First, the participation motives for sports were categorized as follows. A factor analysis conducted on 13 questions yielded 4 factors. Factor 1 included consideration about socializing and pleasure, factor 2 privileged ostentation, factor 3 was concerned with enhancing health, and factor 4 was about maintaining appearance. Second, the various effects of different sports participation motives, of the satisfaction with functionality, and of the involvement in buying sportswear on customers' repurchase intentions were analyzed. The intention to repurchase sportswear was considered as a dependent variable, while the motives for participating in sports, the satisfaction with functionality, and the level of involvement were treated as independent variables. A multiple regression analysis using these variables showed that the satisfaction with functionality and involvement in choosing sportswear had a significant impact on the intention to repurchase sportswear. Third, looking at how different participation motives for sports affected the importance of sportswear functionality, the motives related to socializing and pleasure and ostentation, the sub-factors in sports participation motives, significantly increased the importance of comfort. Motives related to enhancing health and maintaining appearance, on the other hand, were found to affect the importance of sports performance. Fourth, a MANOVA was performed to examine the difference in the importance of functionality between those consumers highly involved in sportswear-buying and those less involved. Those with a high level of involvement were found to prioritize sports performance over comfort. Those with a low level of involvement were shown to place a greater emphasis on comfort.

  • [Purpose] Sodium bicarbonate shows ergogenic potential in physical exercise and sports activities, although there is no strong evidence which performance markers show the greatest benefit from this supplement. This study evaluated the effects of sodium bicarbonate supplementation on time trial performance and time to exhaustion in athletes and sports practitioners. [Methods] A systematic review was conducted using three databases, including 17 clinical trials. Among these clinical trials, 11 were considered eligible for the meta-analysis according to the criteria for the assessment of methodological quality using the PEDro Scale. Time to exhaustion was assessed in six studies, while time trial performance was evaluated in five studies. [Results] A significant beneficial effect of supplementation on time to exhaustion was found in a random effects model (1.48; 95% confidence interval [CI], 0.49 to 2.48). There was no significant effect of supplementation on time trial performance in a fixed effects model (slope = -0.75; 95% CI, -2.04 to 0.55) relative to a placebo group. [Conclusion] Sodium bicarbonate has the potential to improve sports performance in general, especially in terms of time to exhaustion.
