摘要
运动性贫血是限制运动成绩提高的重要因素之一 ,备受运动医学界的重视 ,由于缺乏合适的运动性贫血动物模型 ,许多相关的基础研究受到限制。为了探讨如何建立合适的运动性贫血动物模型 ,本实验分别采用长期递增负荷跑台运动和游泳运动作为实验手段。跑台运动方案以30m/min、0 %坡度和 1min/次为起始 ,运动时间以 2min/次的速度递增、运动频率前 2周为 1次 /天 ,后 3周为 2次 /天。游泳运动方案以 6 0min/次和 0 %负重为起始、16 0min/次和 5 %负重为结束。血红蛋白 (Hb)、红细胞数目 (RBC)和红细胞压积 (Hct)的测试结果显示 ,长期递增负荷的跑台运动方式可能适用于建立运动性贫血动物模型。
Sports anemia is a major factor restricting the improvement of sports performance. Due to successful animal model deficiency, some research projects can not achieve the initial goals as studied for. In this study, effects on erythrocyte indexes after 5 weeks long-term treadmill and swimming exercise were observed. The treadmill exercise started at 30m/min, 0% grade, 1 min duration and gradually increased 2 min each time. Runing frequency shifted from 1 time a day in first 2 weeks to 2 times a day in the next 3 weeks. Swimming protocol started swimming at 60 min/time, without load, ended swimming at 160 min/time, 5% body weight load. Results of hemoglobin (Hb), red blood (cell) count (RBC) and hematocrit (Hct) levels showed that the treadmill exercise was the suitable exercise to establish animal model of sports anemia.
