概括
补充益生菌Lactobacillus acidophilus和Bifidobacterium lactis改善了马拉松跑步者的睡眠质量,并减少了比赛后的白天嗜睡. 这种干预也有助于降低脂多糖 (LPS) 水平,表明潜在的抗炎作用.
科学领域:
- 运动科学 运动科学 运动科学
- 微生物学 微生物学
- 免疫学 免疫学 免疫学
背景情况:
- 睡眠对于运动恢复和表现至关重要.
- 强烈的运动,比如马拉松跑步,会对睡眠产生负面影响,并增加炎症.
- 益生菌可能提供一种减轻运动引起的这些影响的方法.
研究的目的:
- 研究益生菌补充剂对马拉松跑者睡眠质量和炎症标志物的影响.
- 评估马拉松后白天嗜睡,睡眠效率和特定炎症标志物 (细胞因子,LPS) 的变化.
主要方法:
- 一个随机对照试验,涉及27名男子马拉松跑步者.
- 在30天内补充Lactobacillus acidophilus和Bifidobacterium lactis (益生菌组) 或马尔托德克斯 (安慰剂组).
- 评估睡眠参数和炎症概况,在马拉松赛前1小时和24小时,马拉松赛后1小时.
主要成果:
- 与安慰剂组相比,益生菌组在马拉松后24小时报告了更好的睡眠质量和更少的白天嗜睡.
- 马拉松后的益生菌组的总睡眠时间和睡眠效率更高.
- 虽然两组都显示IL-1β,TNF-α和IL-6的降低,但只有益生菌组显示了脂多糖 (LPS) 度的显著降低.
结论:
- 补充Lactobacillus acidophilus和Bifidobacterium lactis30天的时间积极影响马拉松跑者自我报告的睡眠.
- 益生菌的摄入似乎可以降低马拉松后的脂聚糖 (LPS) 水平,这表明它在控制运动引起的炎症方面发挥了作用.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
