■疲劳和胃肠道(GI)困扰在运动员中很常见,估计有30-90%的运动员参加马拉松比赛,铁人三项,或经历GI投诉的类似事件。剧烈运动可导致肠道通透性增加,可能允许肠道微生物群的成员渗透到血液中,导致炎症反应和性能限制结果的级联反应。益生菌,通过它们调节肠道微生物群组成的能力,可以通过增强GI和免疫功能同时减轻炎症反应来作为辅助治疗。这篇综述调查了益生菌补充剂对疲劳的有效性,炎症标志物,和基于随机对照试验(RCTs)的运动表现。
■本综述遵循系统评价和荟萃分析(PRISMA)指南和PICOS(人口,干预,比较,结果,研究设计)框架。在Sportdiscus中进行了全面搜索,PubMed,和Scopus数据库,和标题的筛选,摘要,和完整的文章是根据预定义的资格标准进行的.在确认的3505条记录中,1884年使用标题和摘要进行筛选,其中450项研究被选择用于全文筛选。经过最后的筛选,13项研究符合资格标准,并纳入审查。这项研究包含513名参与者,由351名男性和115名女性组成,然而,两项研究没有提及参与者的性别.在参与者中,246人被定义为运动员,而其余参与者被归类为娱乐活动(n=267)。所有试验都得到了充分描述,并采用了使用单一益生菌菌株或多菌株合生元(包含益生菌和益生元)的双盲或三盲安慰剂对照干预。
■这篇综述评估了每天补充益生菌的效果,从13天到90天,关于各种运动方案中的身体表现和生理指标。十项研究报告了各种参数的改善,例如,增强的耐久性能,改善焦虑和压力水平,胃肠道症状减少,减少上呼吸道感染(URTI)。此外,尽管最大摄氧量(VO2)没有改善,几项研究表明,益生菌补充剂可以改善乳酸,肌酸激酶(CK),和氨浓度,提示对减轻运动引起的肌肉压力和损伤的有益作用。
■益生菌补充剂,特别是每天150亿CFU的最低剂量,持续至少28天,可能有助于减少感知或实际的疲劳。
UNASSIGNED: Fatigue and gastrointestinal (GI) distress are common among athletes with an estimated 30-90% of athletes participating in marathons, triathlons, or similar events experiencing GI complaints. Intense exercise can lead to increased intestinal permeability, potentially allowing members of the gut microbiota to permeate into the bloodstream, resulting in an inflammatory response and cascade of performance-limiting outcomes. Probiotics, through their capacity to regulate the composition of the gut microbiota, may act as an adjunctive therapy by enhancing GI and immune function while mitigating inflammatory responses. This
review investigates the effectiveness of probiotic supplementation on fatigue, inflammatory markers, and exercise performance based on randomized controlled trials (RCTs).
UNASSIGNED: This
review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and PICOS (Population, Intervention, Comparison, Outcome, Study design) framework. A comprehensive search was conducted in Sportdiscus, PubMed, and Scopus databases, and the screening of titles, abstracts, and full articles was performed based on pre-defined eligibility criteria. Of the 3505 records identified, 1884 were screened using titles and abstracts, of which 450 studies were selected for full-text screening. After final screening, 13 studies met the eligibility criteria and were included for
review. The studies contained 513 participants, consisting of 351 males and 115 females, however, two studies failed to mention the sex of the participants. Among the participants, 246 were defined as athletes, while the remaining participants were classified as recreationally active (n = 267). All trials were fully described and employed a double- or triple-blind placebo-controlled intervention using either a single probiotic strain or a multi-strain synbiotic (containing both pro- and pre-biotics).
UNASSIGNED: This
review assesses the effects of daily probiotic supplementation, ranging from 13 to 90 days, on physical performance and physiological markers in various exercise protocols. Ten studies reported improvements in various parameters, such as, enhanced endurance performance, improved anxiety and stress levels, decreased GI symptoms, and reduced upper respiratory tract infections (URTI). Moreover, despite no improvements in maximal oxygen uptake (VO2), several studies demonstrated that probiotic supplementation led to amelioration in lactate, creatine kinase (CK), and ammonia concentrations, suggesting beneficial effects on mitigating exercise-induced muscular stress and damage.
UNASSIGNED: Probiotic supplementation, specifically at a minimum dosage of 15 billion CFUs daily for a duration of at least 28 days, may contribute to the reduction of perceived or actual fatigue.
