Despite accumulating evidence that suggests a unique gut microbiota composition in athletes, a comprehensive understanding of this phenomenon is lacking. Furthermore, seasonal variation in the gut microbiota of athletes, particularly during the off-season, remains underexplored. This study aimed to compare the gut microbiotas between athletic subjects (AS) and non-athletic subjects (NS), and to investigate variations between athletic and off-season periods. The data were derived from an observational study involving Japanese male handball players. The results revealed a distinct gut microbiota composition in AS compared with NS, characterized by significantly higher alpha-diversity and a greater relative abundance of and . Moreover, a comparative analysis between athletic and off-season periods in AS demonstrated a significant change in alpha-diversity. Notably, AS exhibited significantly higher alpha-diversity than NS during the athletic season, but no significant difference was observed during the off-season. This study demonstrates the characteristics of the gut microbiota of Japanese handball players and highlights the potential for changes in alpha-diversity during the off-season. These findings contribute to our understanding of the dynamic nature of the gut microbiota of athletes throughout the season.
尽管越来越多的证据表明运动员的肠道微生物群组成独特，但对这一现象仍缺乏全面的了解。此外，运动员肠道微生物群的季节性变化，尤其是在休赛期，仍未得到充分研究。本研究旨在比较运动员（AS）和非运动员（NS）的肠道微生物群，并调查赛季期和休赛期之间的差异。数据来自一项涉及日本男性手球运动员的观察性研究。结果显示，与NS相比，AS的肠道微生物群组成明显不同，其特征是α多样性显著更高，以及[此处原文缺失具体菌种名称]和[此处原文缺失具体菌种名称]的相对丰度更高。此外，对AS赛季期和休赛期的比较分析表明，α多样性有显著变化。值得注意的是，AS在赛季期间的α多样性显著高于NS，但在休赛期未观察到显著差异。本研究证明了日本手球运动员肠道微生物群的特征，并突出了休赛期α多样性变化的可能性。这些发现有助于我们了解运动员整个赛季肠道微生物群的动态性质。
