The Impact of Weight-Cycling on Resting Metabolic Rate in
Wrestlers and Physically Active Men |
|
|
Weight regulation and metabolic rate are key components of a healthy lifestyle.
In this study, the impact of weight-cycling on metabolic rate and energy in
humans was researched by analyzing the thermal effect of physical activity
(TEA), the thermal effect of food (TEF), and resting metabolic rate (RMR).
Twenty-six men, including active wrestlers and physically active students, were
selected for participation in the study. The RMR, body composition, and body
weight were measured before and after the wrestling season, during which weight
loss was a common practice.
The results showed that weight-cycling wrestlers had higher RMR rates than the
non-weight-cycling group of physically active men. There were no significant
group differences in RMR during any of the periods. Additionally, the
post-season RMR was similar to the pre-season RMR and higher than the other
subjects. This indicates that participating in multiple weight gain and weight
loss cycles over several months did not reduce the RMR in these athletes.
These findings suggest that weight-cycling may not have a negative impact on RMR
in wrestlers and physically active individuals. However, the results should be
used with caution when applied to individuals on a diet. The study highlights
the importance of understanding the role of energy expenditure in weight
regulation and the potential effects of weight-cycling on metabolic rate. |
