Oxidative stress occurs during maximal exercise, perhaps as a result of increased consumption of oxygen. Vitamins C and E can overcome the effects of antioxidants in exercise. We investigated the effects of supplementation with a combination of vitamin C and E (VCE) on blood lipid peroxidation (LP) and antioxidant levels following maximal training in basketball players.Blood samples were taken from 14 players (group A) and divided into two subgroups namely maximal training (group B) and maximal training plus VCE groups (group C). Group B maximally exercised for 35 days. VCE was supplemented to group C for 35 days and blood samples were taken from group B and C. Plasma and hemolyzed erythrocyte samples were obtained from the players.Erythrocyte glutathione peroxidase (GSH-Px) activity and plasma vitamin E concentration were lower in group B than in group A, whereas plasma and erythrocyte LP levels were higher in group B than in group A. Plasma vitamin A, vitamin E, erythrocyte GSH-Px, and reduced glutathione (GSH) values were higher in group C than in groups A and B although LP levels in plasma and erythrocytes were lower in group C than in group A and B. beta-Carotene values did not change in the three groups.In conclusion, VCE supplementation in maximal exercising basketball players may strengthen the antioxidant defense system by decreasing reactive oxygen species (ROS).
在最大运动量时会发生氧化应激，这可能是由于耗氧量增加的结果。维生素 C 和维生素 E 可以克服运动中抗氧化剂的作用。我们研究了在篮球运动员进行最大训练后，补充维生素 C 和 E（VCE）混合物对血液脂质过氧化 (LP) 和抗氧化水平的影响。从 14 名运动员（A 组）中抽取血液样本，并将其分为两个亚组，即最大训练（B 组）和最大训练加 VCE 组（C 组）。B 组最大运动量为 35 天。C 组连续 35 天补充 VCE，并从 B 组和 C 组中抽取血样。从运动员中获得血浆和溶血红细胞样本。红细胞谷胱甘肽过氧化物酶 (GSH-Px) 活性和血浆维生素 E 浓度在 B 组中低于 A 组，而在 B 组中，血浆和红细胞 LP 水平高于 A 组。尽管在 C 组中血浆和红细胞中的 LP 水平低于 A 组和 B 组，但 C 组中血浆维生素 A、维生素 E、红细胞 GSH-Px 和还原型谷胱甘肽 (GSH) 值高于 A 组和 B 组。三组中β-胡萝卜素值均未发生变化。总之，在最大运动量的篮球运动员中补充 VCE 可能通过减少活性氧 (ROS) 来增强抗氧化防御系统。
