摘 要:越来越多的证据表明,运动引起的肠道菌群改变可影响对运动表现至关重要的健康参数,如感染、免疫功能、炎症反应和组织损伤修复等,因此,保持健康的肠道菌群对运动员健康和运动表现至关重要。益生菌作为以活菌为主体的微生态制剂,具有预防肠道感染,调节免疫功能,缓解大强度运动导致的氧化应激、炎症以及物质能量代谢失衡,促进体能恢复和加快疲劳消除等强大生物学功效,其补充可通过改善运动员整体健康水平促进竞技运动表现改善。然而需要注意的是,益生菌的健康促进特性具有高度菌种、菌株和宿主特点等特异性,运动员补充益生菌的菌种和菌株类型、剂量、持续时间、形式和确切效益尚需充分优化。

Abstract:Intestinal flora’s change caused by exercise can affect healthy parameters that are crucial to athletic performance, such as infection, immune function, inflammatory response and tissue repair. Therefore, maintaining healthy intestinal flora is essential to athletes' health and athletic performance. Probiotics can prevent intestinal infection, regulate immune function, alleviate oxidative stress, inflammatory reaction and imbalance of material and energy metabolism, promote physical performance’s recovery and accelerate fatigue’s elimination. Probiotics supplementation based on intestinal flora can improve athletes’ overall healthy level and promote athletic performance. However, it should be noted that probiotics’ health-promoting properties are highly specific to species, strains and hosts. The type, dosage, duration, form and exact benefit of probiotics supplementation for athletes need to be fully optimized.

長期高强度或过度运动训练及不合理的营养、休息等会导致运动员机体产生高应激和高代谢,运动员需具备较高的组织器官适应能力和能量代谢水平,否则会诱发多种不良身心健康问题,如感染、哮喘、胃肠道疾病、炎症失调、免疫抑制、氧化应激、慢性疲劳及抑郁焦虑等,特别是在马拉松、超耐力和铁人三项等长距离项目运动员中,胃肠道功能障碍和内毒素血症等已成为影响其健康并最终影响竞技运动表现的重要负面因素。

伴随着运动、肠道菌群与健康关系研究的深入,肠道菌群在宿主营养、能量代谢、组织损伤修复(如肠道屏障、炎症反应、氧化应激、水合状态)、免疫系统发育成熟等方面的作用已逐渐清晰。……
