吞噬细胞在创伤性肌炎中具有重要影响,但吞噬细胞(特别是单核细胞)在长时间高强度锻炼中的作用研究甚少。通常认为,剧烈运动增加中性粒细胞的吞噬活性,降低了氧化活性。本文旨在探讨补充碳水化合物对运动后粒细胞与单核细胞的影响。 对象与方法 30名有4年以上运动经验,至少参加过两届马拉松比赛的马拉松运动员(VO_(2max)为53.4±1.0 ml/kg/min,平均年龄41.5±1.4岁)。运动员随机分成补充碳水化合物组17例,对照组13例。运动前3d开始控制饮食,确保碳水化合物摄入量占总能量的60％,营养摄入由计算机饮食分析系统进行评估。测试选在5,6月之间,可避免免疫系统的年
Phagocytic cells play an important role in traumatic myositis, but little is known about the role of phagocytes, especially monocytes, in prolonged intensive exercise. It is generally believed that strenuous exercise increases the phagocytic activity of neutrophils and decreases the oxidative activity. This article aims to investigate the effect of carbohydrate supplementation on granulocytes and monocytes after exercise. Subjects and Methods 30 marathon runners with at least two marathons (VO 2max of 53.4 ± 1.0 ml / kg / min and mean age of 41.5 ± 1.4 years) who had at least 4 years of sports experience. Athletes were randomly divided into supplemented carbohydrate group 17 cases, control group 13 cases. Control diet began 3d days before exercise to ensure that carbohydrate intake accounted for 60% of total energy, nutritional intake by the computer diet analysis system to assess. The test is chosen between May and June to avoid years of the immune system
