营养干预对运动性贫血的干预效果

目的]通过对田径运动员采用自行配置的营养补充剂进行营养干预,观察补充后对运动性贫血的治疗效果,为预防和防止运动性贫血提供依据。方法]以氧供能为主的体育运动,要求运动员有较高的有氧能力。本研究纳入正常入学体育系大学生中经常运动的学生中为研究对象,完全随机分配为试验组和对照组,试验组为运动性贫血学生,对照组为正常学生。在学生体育锻炼期间给予试验组铁复合制剂治疗,并服用12周,对照组服用安慰剂治疗。观察实验前和试验后相关红细胞数,血红蛋白浓度和红细胞压积,血清铁、血清铁蛋白以及铁转蛋白以及营养干预对相关指标的影响。结果]女性运动性贫血明显多于男性运动性贫血,实验前贫血组红细胞相关指标、血清铁、血清铁蛋白浓度均低于正常对照组,服用营养干预后干预组的红细胞相关指标,血清铁,血清铁蛋白浓度与实验前相比显著性提高并达到正常值,而血清转铁蛋白显著性的降低。结论]营养干预能有效的改善体内铁紊乱,提高血红蛋白水平和机体铁的贮备量,最终改善运动性贫血。
