Introduction: Soccer tournaments typically feature a competition format that involves multiple matches over a short period of time. While this approach can help reduce costs and scheduling, it often results in insufficient rest intervals between matches for the players. As a result, players may experience cumulative fatigue and muscle damage, leading to decreased sports performance and an increased risk of injury and illness. Although FIFA regulations require a minimum rest interval of at least two days between matches in any official tournament, no previous study has investigated whether the rest intervals between matches in soccer tournaments at different levels actually meet these standards. The aim of the present study, therefore, was to investigate whether tournament organizers took into account the recovery of muscle fatigue/damage and potential injury and health risks to players when scheduling matches. This is an important question for the safety and well-being of soccer players. Methods: Thorough online research was conducted to obtain the final schedule information for various soccer tournaments (e.g., the 2023 Taiwan National Games, the 2022/2023 AFC Asian Cup, the 2020 Summer Olympics Games, the 2022/2023 FIFA World Cup), representing different competitive levels (Taiwan, Asia, World), from the tournaments’official websites. The rest intervals between matches for all participating teams were analyzed using secondary data analysis. Results: (1) The rest intervals between matches at the Taiwan level (43.3±11.4 hours, 17.25–89.3 hours) were significantly shorter than those at the Asia level (85.3±27.9 hours, 41.8–194.6 hours) and the World level (95.1±23.7 hours, 42.2–166.6 hours), while the rest intervals at the Asia level were significantly shorter than those at the World level. (2) At the Asia level, the rest intervals for men’s teams (92.2±30.6 hours, 42.8–194.6 hours) were significantly longer than those for women’s teams (72.3±15.0 hours, 41.8–142.3 hours). At the World level, the rest intervals for women’s teams (102.5±27.1 hours, 66.6–166.6 hours) were significantly longer than those for men’s teams (88.0±17.3 hours, 42.2–146.1 hours). There was no significant difference in the rest intervals between matches for men’s (43.3±9.8 hours, 17.3–70.3 hours) and women’s (43.4±14.4 hours, 22.3–89.3 hours) teams at the Taiwan level. (3) For men’s teams, the rest intervals at the Taiwan level were significantly shorter than those at the Asia and World level, but there was no significant difference between those at the Asia and World level. (4) For women’s teams, the rest intervals at the Taiwan level were significantly shorter than those at the Asia and World level, and the rest intervals at the Asia level were significantly shorter than those at the World level. Conclusion: In the higher-level tournaments, longer rest intervals between matches were scheduled. It seems, however, that players recovery from matches-induced fatigue and muscle damage was not fully taken into account when arranging rest intervals between matches at any tournament level, particularly at lower-level tournaments. This led to an increased risk of injury and illness resulting from playing multiple matches. These results may therefore offer valuable insights to sports organizations for scheduling match rest intervals in future official soccer tournaments. |
