摘要

本研究探讨了添加黑蒜(BG)对运动诱导的氧化应激(EIOS)升高和肌肉功能恢复的影响。在为期14天的研究中,20名健康男性被分配到BG组(n=11, GG)或安慰剂组(n=9, PG)。在肘关节屈肌偏心运动前后,我们测量了肌肉功能、血液生化和尿液生化。两组的最大自主收缩强度在运动后立即下降了35%。运动后3 ~ 7天,GG组肱二头肌周长恢复明显快于PG组。运动后1 ~ 3 d, GG组的活性氧代谢产物(d-ROMs)水平低于PG组,但各组抗氧化电位(BAP)无显著差异。运动诱导的白细胞、单核细胞、淋巴细胞和中性粒细胞均表现出显著的时间效应。运动后第3天,PG组肌酸激酶水平显著高于GG组,运动后3 ~ 7天,PG组过氧化脂质浓度低于PG组,8-异前列腺素F2α水平在运动后各时间点均显著高于GG组。上述结果提示,补充BG对EIOS有一定的抑制作用,并可能促进损伤组织水肿的恢复。

Black Garlic Supplementation's Effect on Exercise-Induced Increase of Oxidative Stress
This study investigated the effects of black garlic (BG) supplementation on exercise-induced increase of oxidative stress (EIOS) and recovery of muscle function. 20 healthy males were assigned to either a BG group (n=11, GG) or placebo group (n=9, PG), during a 14-day-study. Before and after eccentric exercise of elbow flexors, we measured muscle function, blood and urinary biochemistries. Maximal voluntary contraction strength decreased by 35% immediately post exercise in both groups. Recovery of circumference of biceps brachii in GG was significantly faster than in PG during 3-7 days post-exercise. reactive oxygen metabolites (d-ROMs) level was lower in GG than in PG during 1-3 days post-exercise, but no significant difference in anti oxidative potential (BAP) was observed between groups. Exercise induced leukocytosis and monocytes, lymphocytes and neutrophils all exhibited significant time effects. A significantly greater creatine kinase level was found on day 3 post-exercise in PG than in GG. Lipid peroxide concentration was lower during 3-7 days post exercise in GG than in PG and the 8-iso-prostaglandin F2α level was significantly greater in PG than in GG at every post-exercise point. These results suggest that BG supplementation had certain effects on suppression of EIOS and might promote the recovery of edema in injured tissue.
