Abstract

This study investigated whether rooibos herbal tea Aspalathus linearis has an ergogenic effect during a fatiguing arm strength test to exhaustion. Thirty-two male participants were randomised in a single blinded, cross-over placebo controlled study in which they ingested standardised rooibos or placebo capsules for four weeks prior to a fatiguing elbow flexion/extension exercise test entailing five sets/bouts of 15 repetitions of maximum voluntary contractions separated by 10-second rest intervals on a Biodex System 3 at a speed of 60° per second. Peak torque flexion (Nm) was consistently higher in the rooibos experimental (Re) compared to the placebo control (Pc) across the five exercise bouts, and this performance trend during flexion was also seen in the total work (joules) completed, although not significant (P > 0.05). It appears that the antioxidant properties of rooibos, may have contributed to an improvement in physical performance during a maximal isokinetic arm exercise protocol to induce fatigue.

路易波士阿斯巴拉索在运动中作为一种促氧剂的功效

本研究调查了路易波士凉茶是否在疲劳的手臂力量测试中对疲劳产生影响。32名男性参与者被随机分配到一项单盲、交叉安慰剂对照研究中，在进行疲劳肘关节屈伸运动测试之前，他们服用标准化的路易波士或安慰剂胶囊4周，该测试包括5组/组15次的最大自主收缩，每组15次重复，在Biodex System 3上以每秒60度的速度休息10秒。在五个运动回合中，路易波士实验组(Re)的峰值扭矩屈曲(Nm)始终高于安慰剂对照组(Pc)，屈曲期间的这种表现趋势也出现在完成的总工作量(焦耳)中，尽管不显著(P > 0.05)。看来，路易波士的抗氧化特性可能有助于在最大等速手臂运动方案中改善身体表现，以诱导疲劳。
