Introduction: Engaging in eccentric exercise can easily lead to significant muscle damage. Basketball, as an open-skill sport, involves many movements that require eccentric muscle actions. However, to the best of our knowledge, no previous study has systematically investigated whether the rest intervals between matches at different levels of basketball tournaments affect sports performance, contribute to cumulative fatigue, and increase injury risk from the perspective of player protection. Therefore, this study aimed to examine the above research questions. Methods: The latest schedule information was obtained from the official websites of three levels of basketball tournaments (e.g., 2021/2023 Women’s/Men’s National Amateur Basketball Championship; 2022/2023 Men’s/Women’s Basketball Asia Cup; 2022/2023 FIBA Basketball World Cup). Secondary data analysis was used to evaluate the rest intervals (in hours) between matches for all participating teams in each tournament. Relevant literature was reviewed and analyzed to infer the potential effects of short rest intervals on athletic performance, fatigue, and injury risk in these congested tournament schedules. Results: (1) Rest intervals between matches at different levels (combined for men’s and women’s): The average rest interval at the Taiwan level (28.2±13.1 hours) was significantly shorter (p < .05) than at both the Asia level (42.8±15.5 hours) and World level (49.0±15.8 hours), with the Asia level also being significantly shorter than the World level. (2) Rest intervals by gender across levels: Rest intervals for men’s matches were significantly longer (p < .05) than those for women’s matches across all three tournament levels. (3) Rest intervals within each gender by level: For both men’s and women’s tournaments, the Taiwan level rest intervals were significantly shorter (p < .05) than those at the Asia and World levels, with the Asia level also being significantly shorter than the World level. (4) Literature findings: Previous studies have shown that a single basketball match can induce muscle damage lasting at least two days, and that congested schedules, or multiple matches increase the risk of injury and negatively impact athletic performance. Conclusion: These results indicate that the scheduling of rest intervals at all tournament levels does not sufficiently consider the impact on recovery, injury risk, and sports performance. Therefore, these findings will be presented to basketball tournament organizers as a reference for developing future guidelines and regulations. |
