To investigate the effects of 6 weeks of quercetin supplementation on physical performance during military physical training.
Using a randomized, double-blind, repeated-measures, placebo-controlled design, 58 healthy, moderately trained men and women were randomly assigned to quercetin (Q) or placebo (P) groups. Peak oxygen uptake (VO(2peak)) during maximal effort uphill treadmill running and four physical performance measures (Army Physical Fitness Test, [APFT], Baumgartner Modified Pull-Up Test [BMPU], Wingate Anaerobic Test [WanT], and a 36.6-m sprint) were evaluated before and after 42-54 days of supplementation with 1 g/d of quercetin with vitamins and other substances in a soft chew or placebo chew.
Pretreatment-to-posttreatment changes in VO(2peak) and physical performance were not significantly different (p > 0.05) in Q and P.
Six weeks of dietary quercetin supplementation in moderately trained individuals conducting military physical training did not improve VO(2peak) or performance on the APFT, BMPU, WAnT, and 36.6-m sprint.
研究补充槲皮素6周对军事体能训练期间身体表现的影响。
采用随机、双盲、重复测量、安慰剂对照设计，将58名健康、训练适度的男性和女性随机分为槲皮素（Q）组或安慰剂（P）组。在补充1克/天的含维生素和其他物质的软咀嚼型槲皮素或安慰剂咀嚼片42 - 54天后，评估最大努力上坡跑步机跑步时的峰值摄氧量（VO₂peak）以及四项身体表现指标（陆军体能测试[APFT]、鲍姆加特纳改良引体向上测试[BMPU]、温盖特无氧测试[WanT]和36.6米短跑）。
Q组和P组VO₂peak及身体表现从治疗前到治疗后的变化无显著差异（p > 0.05）。
在进行军事体能训练的训练适度个体中，补充膳食槲皮素6周并未改善VO₂peak或在APFT、BMPU、WAnT和36.6米短跑中的表现。
