摘要
这项系统综述和荟萃分析评估了碳酸氢钠（NaHCO₃）补充剂对游泳者200米计时赛成绩和生理反应的影响，遵循PRISMA指南。在五个数据库中进行了全面的搜索，确定了比较NaHCO₃和安慰剂的符合条件的随机对照试验。结果为200 m时间、血碳酸氢盐、血乳酸和血ph。结果显示血碳酸氢盐显著升高(SMD = 1.09, 95% CI = 0.38 ~ 1.79， P
Effects of sodium bicarbonate on 200 m time trial performance and physiological responses in swimmers: a systematic review and meta-analysis of randomized controlled trials.
This systematic review and meta-analysis evaluated the effects of sodium bicarbonate (NaHCO₃) supplementation on 200 m time trial performance and physiological responses in swimmers, following PRISMA guidelines. A comprehensive search across five databases identified eligible randomized controlled trials comparing NaHCO₃ with placebo. Outcomes were 200 m time, blood bicarbonate, blood lactate, and blood pH. Results showed significant increases in blood bicarbonate (SMD = 1.09, 95% CI = 0.38 to 1.79, P<0.01), blood lactate (SMD = 0.76, 95% CI = 0.24 to 1.29, P<0.01) and blood pH (SMD = 1.02, 95% CI = 0.33 to 1.71, P<0.01), but no effect on 200 m time (SMD = 0.26, 95% CI -0.58 to 1.10). These findings suggest NaHCO₃ enhances certain physiological responses but does not improve 200 m performance, though data limitations require cautious interpretation.
