The effect of calcium pyruvate on physical compositions and rest metabolic rate of wrestlers
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(P0.05);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(P0.05);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.
