The Weight Reducing Effects of Three Different Protein Content Diets Combined with Aerobic Exercise on Body Composition and Physical Working Capacity of Male College Weight Lifters.

目前的研究审查了三种不同蛋白质含量饮食计划的影响。（A组（n=3） ： 1.5 g·kg^<-1>·day^<-1>， B组（n=5） ： 1.8 g·kg^<-1>·day^<-1>， C组（n=4） ：2.3 g·kg^\-1>·Day^\-1\） combined with aerobic exercise for male college weight Management ters on weight reduction in preparation for competitions。身体成分（水下重量）、物理工作能力（肌肉强度和最大模拟功率输出）、血液成分和初级硝基浓缩（联合国）在节食前和最后阶段进行了测量。节食的时间是20天。A组平均每日含有1816千卡，含98.8克蛋白质（1.5克·kg^<-1>·天^<-1>），1906千卡，含122.1克蛋白质（1.8克·kg^<-1>·天^<-1>），含1712千卡，含150.8克蛋白质（2.3克·kg^<-1>·天^<-1>）。节食后，所有团体的身体重量减少为1.81公斤 *2.80公斤。LBW减为0.66公斤和1.25公斤，相当于A组和B组。C组的身体重量中的分解是所有的身体脂肪。联合国对氮素平衡的估计值（-1.61克）仅在一组中。在所有群体中，物理工作能力并没有显示任何变化，而且大多数血液常量仍然处于正常范围内。这些数据提出了高蛋白质饮食方案（2.3 g·kg^<-1>·日^<-1>）的结果，并将航空运动与体重减轻（2.0 g·kg^<-1>·日^<-1>）的结果结合起来。本研究包括一个高蛋白质饮食计划（2.0克·千克^<-1>·天^<-1>），与超重救生员中的有氧运动结合在一起，是最危险的。

The present study examined the effect of three different protein content diet program (A group (n=3) : 1.5 g・kg^<-1>・day^<-1>, B group (n=5) : 1.8 g・kg^<-1>・day^<-1>, C group (n=4) : 2.3 g・kg^<-1>・day^<-1>) combined with aerobic exercise for male college weight lifters on weight reduction in preparation for competitions. Body composition (under-water weighing), physical working capacity (muscle strength and maximal anaerobic power output), blood constituents and urinary nitrogen excretion (UN) were measured before and at the last stage of the dieting. The period of dieting was 20 days. The average daily contained 1816 kcal with 98.8 g of protein (1.5 g・kg^<-1>・day^<-1>) for A group, l906kcal with 122.1 g of protein (1.8 g・kg^<-1>・day^<-1>) for B group, 1712 kcal with 150.8 g of protein (2.3 g・kg^<-1>・day^<-1>) for C group. After dieting, body weight of all groups decreased 1.81 kg*2.80 kg of the range. The LBW decreased 0.66kg, 1.25 kg in A and B groups, respectively. The decrease in body weight of C group was all body fat. The estimated value of the nitrogen balance from UN was negative (-1.61 g) only in A group. In all groups, the physical working capacities did not show any changes, and most blood constituents were still in normal ranges. These data suggested that results of a high protein diet program(2.3 g・kg^<-1>・day^<-1>) combined with aerobic exercise in weight lifters consisted of our pre-study (2.0 g・kg^<-1>・day^<-1>) result. This study conclude that a high protein diet program (2.0 g・kg^<-1>・day^<-1>) combined with aerobic exercise in weight lifters was most adequacy.
