摘要
目的 探讨营养补充剂提升血红蛋白水平低下手球运动员耐力跑能力的效果。方法 选取安徽省参加全国第十四届运动会预赛的女子手球运动员12名,把耐力跑测试结果低于全运会门槛标准的5名运动员设为观察组,其他7名运动员设为对照组。对照组和观察组均按照赛前训练计划进行,饮食统一管理,每日三餐均在运动员餐厅正常饮食。观察组增加阿胶、叶酸、多维元素片、硫酸亚铁等营养补充剂进行综合干预,干预时间为8周。比较干预前、后运动员体能指标耐力跑成绩,生化指标血红蛋白、血清铁蛋白、血尿素氮、血清肌酸激酶、血清睾酮与皮质醇。结果 干预8周后,观察组耐力跑成绩提高,且成绩提高幅度高于对照组(P<0.05);观察组血红蛋白水平提高,提高幅度高于对照组(P<0.05);观察组血清转铁蛋白水平提升,提升幅度高于对照组(P<0.05)。结论 营养补充剂能有效提高血红蛋白水平低下手球运动员耐力跑能力并提高了运动员血红蛋白水平。
Objective Exploring the effect of nutritional supplements on improving endurance running ability in handball players with low hemoglobin levels.Methods Twelve female handball players from Anhui Province who participated in the preliminary round of the 14th National Games were selected.Five athletes whose endurance running test results were lower than the threshold standard of the National Games were selected as the observation group,and the other seven athletes were selected as the control group.Both the control group and the observation group were trained according to the pre competition training plan,and their diet was managed uniformly.They ate three meals a day at the athletes' restaurant as usual.The observation group added ass hide glue,folic acid,Vitamins With Minerals Tablets(29),ferrous sulfate and other nutritional supplements for comprehensive intervention,and the intervention training was 8 weeks.Compare the biochemical indicators of hemoglobin,serum ferritin,blood urea nitrogen,serum creatine kinase,serum testosterone,cortisol and physical fitness indicators of endurance running performance in athletes before and after intervention.Results After 8 weeks of intervention,the endurance running performance of the experimental group improved(P<0.05),and compared with the control group,the improvement in performance was higher(P<0.05);The hemoglobin level in the experimental group increased(P<0.05),and the increase was higher than that in the control group;The serum transferrin level in the experimental group increased(P<0.05),and the increase was higher than that in the control group(P<0.05).Conclusion Drug intervention combined with lactate tolerance training can effectively improve the endurance running ability and hemoglobin level of female athletes.
