Exhaustive Aerobic Exercise (EAE) increases the production of free radicals and oxidative stress in the body. One of the most effective approaches to reduce EAE-induced oxidative stress is antioxidant supplementation.
Therefore, the present study investigated the effect of short-term Vitamin D (Vit D) supplementation on antioxidant capacity in inactive men following an EAE session.
In this clinical trial, 24 non-athlete men were randomly divided into Experimental (Exp; n = 12) and Control (C; n = 12) groups. Exp received 2,000 IU of Vit D daily for six weeks (42 days), while C received a lactose placebo daily with the same color, shape, and warmth percentage. EAE sessions were performed on a treadmill before and after six weeks of supplementation.
The results showed that EAE increased antioxidant capacity and Vit D (P<0.05). Compared with C, six weeks of Vit D supplementation significantly increased superoxide dismutase (P=0.001), glutathione peroxidase (P=0.011), catalase (P=0.018), peroxidase (P=0.001), and Vit D (P=0.001), in the Exp at the Post 2 stage.
Finally, short-term Vit D supplementation could be recommended to non-athlete men deciding to participate in EAE to prevent oxidative damage.
剧烈有氧运动(EAE)会增加体内自由基和氧化应激的产生。减轻 EAE 引起的氧化应激的最有效方法之一是抗氧化剂补充。
因此,本研究调查了短期维生素 D(Vit D)补充对 EAE 运动后非运动员男性抗氧化能力的影响。
在这项临床试验中,24 名非运动员男性被随机分为实验组(Exp;n = 12)和对照组(C;n = 12)。Exp 每天接受 2,000 IU 的 Vit D 补充剂,持续 6 周(42 天),而 C 每天接受相同颜色、形状和温暖百分比的乳糖安慰剂。在补充 6 周前后,在跑步机上进行 EAE 运动。
结果表明,EAE 增加了抗氧化能力和 Vit D(P<0.05)。与 C 相比,六周的 Vit D 补充显著增加了超氧化物歧化酶(P=0.001)、谷胱甘肽过氧化物酶(P=0.011)、过氧化氢酶(P=0.018)、过氧化物酶(P=0.001)和 Vit D(P=0.001),在 Exp 的 Post 2 阶段。
最后,建议决定参加 EAE 的非运动员男性短期补充 Vit D,以预防氧化损伤。
