To determine the effect of multiple cycles of weight loss and regain on resting metabolic rate (RMR), we compared RMR between 12 weight-cycling collegiate wrestlers (means age 19.4 y) with a minimum of three previous seasons of weight cycling and 13 weight-stable nonwrestlers of similar weight and body composition (means age 20.6 y). RMR was measured before, during, and after a 6-mo wrestling season. Wrestlers exhibited a significantly higher baseline RMR compared with the control subjects (p less than 0.05). During the season when wrestlers had lost weight for competition, RMR was reduced (p less than 0.05) but was not significantly lower than that of the weight-stable control subjects. After a season of weight cycling and the final weight regain, the wrestler's postseason RMR was similar to preseason values and higher than the postseason RMR of the control subjects (p less than 0.05). Participation in numerous cycles of weight loss and regain did not lower RMR in these competitive athletes, as has been previously suggested.
为了确定多次减重和体重恢复周期对静息代谢率（RMR）的影响，我们比较了12名有多次体重循环经历的大学摔跤运动员（平均年龄19.4岁，至少有三个赛季的体重循环经历）和13名体重稳定、体重及身体组成相似的非摔跤运动员（平均年龄20.6岁）的静息代谢率。在一个6个月的摔跤赛季之前、期间和之后测量静息代谢率。与对照组相比，摔跤运动员的基线静息代谢率显著更高（p<0.05）。在赛季中，当摔跤运动员为比赛而减重时，静息代谢率降低（p<0.05），但并不显著低于体重稳定的对照组。经过一个赛季的体重循环和最终体重恢复后，摔跤运动员赛季后的静息代谢率与赛季前的值相似，且高于对照组的赛季后静息代谢率（p<0.05）。正如之前所认为的那样，参与多次减重和体重恢复周期并没有降低这些竞技运动员的静息代谢率。
