Spirulina plantensis is a popular supplement which has been shown to have antioxidant and performance enhancing properties. The purpose of this study was to evaluate the effects of spirulina supplementation on (a) redox status (b) muscle performance and (c) muscle damage following an eccentric bout of exercise that would induce muscle damage. Twenty-four healthy, recreationally trained males participated in the study and were randomly separated into two groups: a spirulina supplementation (6 g per day) and a placebo group. Both groups performed an eccentric bout of exercise consisting of 5 sets and 15 maximum reps per set. Blood was collected at 24, 48, 72 and 96 h after the bout and total antioxidant capacity (TAC) and protein carbonyls (PC) were assessed in plasma. Delayed onset muscle soreness (DOMS) was also assessed at the same aforementioned time points. Eccentric peak torque (EPT) was evaluated immediately after exercise, as well as at 24, 48, 72 and 96 h post exercise. Redox status indices (TAC and PC) did not change significantly at any time point post exercise. DOMS increased significantly 24 h post exercise and remained elevated until 72 h and 96 h post exercise for the placebo and spirulina group, respectively. EPT decreased significantly and immediately post exercise and remained significantly lower compared to baseline until 72 h post exercise. No significant differences between groups were found for DOMS and EPT. These results indicate that spirulina supplementation following a muscle damaging protocol does not confer beneficial effects on redox status, muscle performance or damage.
钝顶螺旋藻是一种广受欢迎的补充剂，已被证明具有抗氧化和增强运动表现的特性。本研究的目的是评估补充螺旋藻对以下方面的影响：（a）氧化还原状态；（b）肌肉性能；（c）一次可导致肌肉损伤的离心运动后肌肉损伤情况。24名健康的、进行休闲训练的男性参与了这项研究，并被随机分为两组：螺旋藻补充组（每天6克）和安慰剂组。两组都进行了一次离心运动，包括5组，每组15次最大重复次数。在运动后24、48、72和96小时采集血液，评估血浆中的总抗氧化能力（TAC）和蛋白质羰基（PC）。在上述相同时间点也评估了延迟性肌肉酸痛（DOMS）。在运动后立即以及运动后24、48、72和96小时评估离心峰值扭矩（EPT）。氧化还原状态指标（TAC和PC）在运动后的任何时间点均未发生显著变化。安慰剂组和螺旋藻组的DOMS在运动后24小时显著增加，分别在运动后72小时和96小时保持升高。EPT在运动后立即显著下降，与基线相比，直到运动后72小时仍显著较低。在DOMS和EPT方面，两组之间未发现显著差异。这些结果表明，在肌肉损伤方案后补充螺旋藻对氧化还原状态、肌肉性能或损伤没有产生有益影响。
