本文对水球、举重运动员集训期膳食及蛋白质供给情况进行调查,对受试运动员进行了膳食调查,氮平衡试验,尿负荷试验、检测血红蛋白、血清总蛋白。结果发现每天热能摄入:水球队为59.22±6.61千卡/公斤体重,举重队为46.35±7.05千卡/公斤体重,两队运动员一周内体重基本保持不变,蛋白质、脂肪摄入偏高、糖摄入不足,氮平衡试验除二名水球运动员出现负氮平衡原因待查外,其余运动员均示平衡或轻度正氮平衡,钙、磷、铁摄入充足,且钙、磷比例合适,血红蛋白和血清总蛋白含量均高于正常值,膳食调查和尿负荷试验示两队运动员维生素C(下简称Vc)摄入量基本满足机体需要,V_A、V_B_1、V_B_2、V_(PP)均示不足。运动员脂肪摄入过多和糖不足。作者认为对运动员提供合理膳食和科学安排食谱是很重要的。
In this paper, the water polo and weightlifter training during the training diet and protein supply were investigated, the test athletes dietary studies, nitrogen balance test, urine load test, detection of hemoglobin, serum total protein. The results showed that daily calorie intake: water polo team was 59.22 ± 6.61 kcal / kg body weight, weightlifting team was 46.35 ± 7.05 kcal / kg body weight, body mass within two weeks of athletes remain basically unchanged, protein, fat intake is high , Inadequate intake of sugar, nitrogen balance test except two polo players negative nitrogen balance to be found out, the remaining athletes showed a balanced or mild positive nitrogen balance, adequate intake of calcium, phosphorus and iron, and calcium, phosphorus ratio is appropriate, Hemoglobin and serum total protein content were higher than normal, dietary surveys and urine load test showed that the two teams of athletes vitamin C (hereinafter referred to as Vc) intake basically meet the body needs, V_A, V_B_1, V_B_2, V_ (PP) . Athlete fat intake and lack of sugar. The author believes that it is important for athletes to provide a reasonable diet and to arrange the scientific diet.
