【摘要】：目的:研究补充虾青素及急性大强度运动对人体血清抗氧化能力、血乳酸及血尿酸代谢的影响。方法:将16名体育学院男生随机分为实验组A和对照组B(每组8人)。A组以中等剂量(12mg/d)服用虾青素28天,B组服用安慰剂28天。4周后,所有受试者进行急性大强度运动,即全力骑功率自行车30s×3/间歇3 min,负荷为0.075kg/kg体重。分别在服药前、服药后(运动前)、运动后即刻、运动后1h采集所有受试者的血液样本并检测其抗氧化能力值、血乳酸及血尿酸值。结果:1)中等剂量服用虾青素4周可显著提高受试者的抗氧化能力(P0.01),降低血乳酸水平(P0.05)及血尿酸水平(P0.05);2)急性大强度运动后即刻,两组受试抗氧化能力值均下降(P0.05),血乳酸值均明显升高(P0.01),但实验组抗氧化能力值明显高于对照组(P0.05),血乳酸值低于对照组(P0.05),两组受试者血尿酸值虽均有下降,但无统计学差异,实验组仍略低于对照组(P0.05);3)运动后1h,两组受试者抗氧化能力值均明显上升(P0.05),实验组显著高于对照组(P0.01),血乳酸值均明显下降(P0.01),实验组显著低于对照组(P0.05),血尿酸值均明显上升(P0.01),实验组显著低于对照组(P0.05)。结论:1)连续4周服用中等剂量虾青素可显著提高人体在安静状态下的抗氧化能力,降低血乳酸、血尿酸含量;2)可改善急性大强度运动后人体抗氧化能力的降低程度和恢复程度,血乳酸及血尿酸的产生程度和清除速度。
[Abstract]:Objective: to study the antioxidant effect of astaxanthin supplementation and acute high-intensity exercise on human serum. Methods: sixteen male students in physical education college were randomly divided into two groups: group A (n = 8) and group B (n = 8) treated with astaxanthin at a medium dose of 12 mg / d for 28 days. Group B was given placebo for 28 days. 4 weeks later, all subjects underwent acute high-intensity exercise, which was 30 seconds 脳 3 seconds / interval 3 min. The load was 0.075 kg / kg body weight. The blood samples of all subjects were collected before and after taking medicine (immediately after exercise, immediately after exercise, 1 hour after exercise) and their antioxidant capacity values were measured. Results the medium dose of astaxanthin for 4 weeks could significantly improve the antioxidant ability of the subjects (P0.01). The levels of blood lactic acid and uric acid were decreased (P0.05) and the levels of serum uric acid (P0.05) were decreased. 2) immediately after acute high-intensity exercise, the value of antioxidant capacity decreased and blood lactic acid increased significantly in both groups (P 0.05 and P 0.01). However, the value of antioxidant capacity in the experimental group was significantly higher than that in the control group (P 0.05), and the value of blood lactic acid was lower than that of the control group (P 0.05). Although the blood uric acid values of the two groups were all decreased, there was no statistical difference between the two groups. The experimental group was still slightly lower than the control group (P 0.05). 3) at 1 hour after exercise, the values of antioxidant capacity in both groups were significantly higher than those in the control group (P 0.05), and the blood lactic acid values in the experimental group were significantly lower than those in the control group (P 0.01). The blood uric acid value in the experimental group was significantly higher than that in the control group (P 0.01). Conclusion taking astaxanthin for 4 weeks in the experimental group can significantly improve the antioxidant capacity and decrease the contents of blood lactic acid and uric acid. 2) it can improve the degree of decrease and recovery of antioxidant ability, the production of blood lactic acid and uric acid and the clearance rate after acute intensive exercise.

【正文快照】： 自20世纪50年代起,生物学家和医学工作者开始认识和研究自由基。自由基性质活泼,易与脂类、蛋白质、DNA等发生反应使其自身结构稳定,这一过程即为“氧化”。人体在新陈代谢过程中不可避免会产生少量自由基,人体自身也具有清除自由基的能力,正常状态下,人体自身的氧化还原反应
