【摘要】 运动性低血色素是影响运动能力的重要因素之一,但处于运动性低血色素状态时骨骼肌自由基代谢变化规律目前研究较少,本实验通过11周递增负荷跑台运动建立大鼠运动性低血色素模型,并对大鼠骨骼肌自由基代谢的变化进行研究,了解运动性低血色素大鼠骨骼肌自由基代谢变化的规律。实验结果表明:1、递增负荷跑台训练导致运动性低血色素大鼠骨骼肌中抗氧化酶活性明显降低,是造成自由基代谢紊乱的重要因素;2、运动性低血色素大鼠Hb水平下降与骨骼肌SOD水平下降具有相关性。更多还原

【Abstract】 Exercise-induced hypochrosis is one of the main factors which affect sports performance,but few researches have focused on the metabolism of free radicals in skeletal muscles when sports hypochrosis happens.This research has established an animal model of exercise-induced hypochrosis and investigates the metabolism of free radicals in skeletal muscles.The results indicate that the activities of anti-oxidases decrease when sports hypochrosis happens after treadmill exercises and the decrease of Hb level is related to the decrease of SOD level in skeletal muscles.更多还原
