Abstract des Autors
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 (mean age 19.4 y) with a minimum of three previous seasons of weight cycling and 13 weight-stable nonwrestlers of similar weight and body copmposition (mean 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<0.05). During the season when wrestlers had lost weight for competition, RMR was reduced (p<0.05) but was not significantly lower than of the weight-stable control subjects. After a season of weight cycling and the final weight regain, the wrestlers' postseason RMR was similar to preseason values and higher than the postseason RMR of the control subjects (p<0.05). Participation in numerous cycles of weight loss and regain did not lower RMR in these competitive athletes, as has been previously suggested. Verf.-Referat
