| 摘 要： | 探讨丙酮酸钙对摔跤运动员体成分和静息代谢率的影响。选取摔跤男运动员22人，随机分成2组即丙酮酸钙组和安慰荆组，分别给予6g／d的丙酮酸钙和安慰荆，共服用8周。观察摔跤运动员体重、体脂肪含量、体重指数、身体脂肪比率以夏腹部脂肪比率、去脂体重、肌肉量、骨骼肌含量、水分、蛋白质、无机盐含量以及静息代谢率的变化。结果表明实验束丙酮酸钙纽体重、体脂肪含量、体重指数、身体脂肪比率以厦腹部脂肪比率5项指标均较实验前呈显著下降（P〈0．05）；安慰剂组体重、去脂体重、肌肉量、体脂肪、体重指数、身体脂肪比率、腹部脂肪比率、水分、蛋白质、无机盐含量以及静息代谢率各项指标与实验前比较有所下降，但无显著意义；组间进行比较，丙酮酸钙组实验前后体重差值、体脂肪含量差值、身体脂肪比率差值以及腹部脂肪比率差值4项指标与安慰刺组相比差异存在显著（P〈0．05）；去脂体重、肌肉量、骨骼肌含量、水分、蛋白质、无机盐含量以及静息代谢率在实验前后和两组间均无明显变化。可见，丙酮酸钙能有效降低摔跤运动员体重和体脂含量而不影响去脂体重，迭到减重而不减瘦体重的目的；丙酮酸钙对于静息代谢率无明显影响。

| Abstract: | To probe into the effect of calcium pyruvate on physical compositions and rest metabolic rate of wrestlers,the authors selected 22 male wrestlers and randomly divided them into 2 groups,namely calcium pyruvate group and placebo group,which were given 6g of calcium pyruvate and placebo a day respectively for totally 8 weeks.Having observed the trend of variation of the body weight,body fat content,body weight index,body fat radio,abdominal fat radio,degreased body weight,muscle content,skeletal muscle content;water content,protein,inorganic salt content and rest metabolic rate of the wrestlers,the authors revealed the following findings: At the end of the experiment,such 5 indices as body weight,body fat content,body weight index and body fat radio of the wrestlers in calcium pyruvate group were significantly lower than those before the experiment(P<0.05);various indices such as body weight,degreased body weight,muscle content,body fat,body weight index,body fat radio,abdominal fat radio,water content,protein,inorganic salt content and rest metabolic rate of the wrestlers in placebo group were somewhat lower than those before the experiment,but such a decrement had no meaning of significance.In comparison between the two groups,such 4 indices as differences of body weight,body fat content,body fat radio and abdominal fat radio of the wrestlers in calcium pyruvate group before and after the experiment had a significant discrepancy as compared with those of the wrestlers in placebo group(P<0.05);no obvious trend of variation occurred to the degreased body weight,muscle content,skeletal muscle content,water content,protein,inorganic salt content and rest metabolic rate of the wrestlers in both groups before and after the experiment.Evidently,calcium pyruvate can effectively lower the body weight and body fat content of a wrestler without affecting his degreased body weight,thus achieving to goal of losing weight without losing lean body mass;calcium pyruvate has no significant effect on rest metabolic rate. |
