目的:观察服用耐力复合胶囊对军事五项队运动员大负荷专项训练期间身体机能及运动能力的影响。方法:20名运动员按运动等级和性别分层后随机分成实验组和对照组。除每天正常大负荷训练外,实验组补充补血耐力复合胶囊,对照组补充淀粉胶囊,连续服用4周。在实验第0周、2周和4周采静脉血测定红细胞计数(RBC)、血红蛋白(Hb)、红细胞压积(HCT)、平均红细胞体积(MCV)、平均红细胞血红蛋白量(MCH)、平均红细胞血红蛋白浓度(MCHC)、红细胞体积分布宽度(RDW)、血清铁蛋白(SF)、超氧化物歧化酶(SOD)活性、丙二醛(MDA)水平。实验前后进行跑台最大摄氧量和自行车无氧功的测试。结果表明:补血耐力复合胶囊能有效维持军事五项运动员大负荷训练期血红蛋白和红细胞压积水平,提高铁蛋白含量,增加体内铁贮备,有显著的抗自由基作用,能有效维持机体的最大摄氧量、平均功率和总功率,提高无氧最大功率。
OBJECTIVE: To observe the effects of taking endurance compound capsules on body function and exercise capacity during heavy load special training of military pentathlon athletes. Methods: Twenty athletes were randomly divided into experimental group and control group according to exercise grade and sex stratification. In addition to the normal daily heavy load training, the experimental group supplemented with blood and endurance compound capsules, the control group added starch capsules, taking 4 consecutive weeks. The RBC, Hb, HCT, MCV, MCH, mean erythrocyte (RBC) Hemoglobin concentration (MCHC), erythrocyte volume distribution width (RDW), serum ferritin (SF), superoxide dismutase (SOD) activity and malondialdehyde (MDA) Before and after the test treadmill maximum oxygen uptake and bicycle anaerobic test. The results showed that the blood - enriching and endurance compound capsules can effectively maintain the hemoglobin and hematocrit of the heavy load training period of the military pentathletes, increase the content of ferritin, increase the iron storage in the body, have a significant anti - free radical effect, and can effectively maintain the maximum photogenicity of the body Oxygen, average power and total power, increase the maximum oxygen-free power.
