Purpose: This study investigates the role of authenticity in the effect of CSV activities of sports firms on corporate trust based on the attribution theory. Although many studies have been conducted on CSV, studies on the sports firms' CSV activities and their authenticity are insufficient. Methods: This study surveyed consumers who have experienced CSV activities of sports firms. The data were analyzed using structural equation model and hierarchical regression analysis. Results: The results showed that sports firms' CSV activities significantly affected corporate trust and authenticity played an important role in regulating the impact of CSV activities on corporate trust. The more authenticity was recognized by customers, the higher the performance of sports firms' CSV activities. Conclusion: These results imply that it is important to establish authentic CSV strategy, as performance of CSV activities is mainly determined by authenticity.

[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.
