Abstract

This systematic review and meta-analysis aimed to determine the effect of combined beta-alanine (BA) and sodium bicarbonate (SB) supplementation on exercise capacity and performance. Four databases (PubMed, SPORTDiscus, Web Of Science and MEDLINE) were searched using relevant terms for studies involving healthy (e.g. no chronic diseases or conditions) male or female adults of any training status (athletes, physically active and non-athletes) and that investigated BA and SB in isolation and combination at any dose on an exercise outcome. Ten studies, totalling 243 individuals, met the criteria with 12 outcomes for each nutritional supplement. No ergogenic effect was detected in this meta-analysis for BA (SMD = 0.18, 95% CI: -0.06; 0.43, p = 0.13, tau2 = 0, tau = 0, I2 = 0.0%) or SB (SMD = 0.17, 95% CI: -0.08; 0.41, p = 0.16, tau2 = 0, tau = 0, I2 = 0.0%) in isolation. However, there was a beneficial effect for the combination of BA and SB (SMD = 0.32, 95% CI: 0.07; 0.57, p = 0.02, tau2 = 0, tau = 0, I2 = 0.0%). Meta-regression identified no differences between supplementing with BA or SB separately (F = 0.58; p = 0.57). Combining BA and SB improved exercise performance, however, there was no benefit in taking these supplements individually.

补充碳酸氢钠和 beta-丙氨酸:两者结合是否比单独使用其中一种更好?系统回顾和荟萃分析。
本系统综述和荟萃分析旨在确定联合补充 beta-丙氨酸(BA)和碳酸氢钠(SB)对运动能力和表现的影响。我们使用相关术语在四个数据库(PubMed、SPORTDiscus、Web Of Science 和 MEDLINE)中搜索了涉及任何训练状态(运动员、体能活动者和非运动员)的健康(如无慢性疾病或病症)男性或女性成年人的研究,这些研究调查了任何剂量下单独或联合补充 BA 和 SB 对运动结果的影响。符合标准的研究有 10 项,共计 243 人,每种营养补充剂有 12 种结果。在这项荟萃分析中,没有发现单独使用 BA(SMD = 0.18,95% CI:-0.06; 0.43,p = 0.13,tau2 = 0,tau = 0,I2 = 0.0%)或 SB(SMD = 0.17,95% CI:-0.08; 0.41,p = 0.16,tau2 = 0,tau = 0,I2 = 0.0%)有增强运动能力的效果。然而,BA 和 SB 的组合具有有益效果(SMD = 0.32,95% CI:0.07; 0.57,p = 0.02,tau2 = 0,tau = 0,I2 = 0.0%)。元回归发现,单独补充 BA 或 SB 之间没有差异(F = 0.58;P = 0.57)。结合使用 BA 和 SB 可提高运动表现,但单独服用这些营养补充剂并无益处。
