EFFECTS OF MEAL FREQUENCY ON BODY-COMPOSITION DURING WEIGHT CONTROL IN BOXERS

The effects of meal frequency on changes in body composition by food r estriction were investigated. Twelve boxers were divided between a two meals day(-1) group (the 2M group) and a six meals day(-1) group (the 6M group). Both groups ingested 5.02 MJ (1200 kcal) day(-1) for 2 wee ks. Although there was no difference in change of body weight by food restriction between the two groups, the decrease in lean body mass (LB M) was significantly greater in the 2M group than in the 6M group. The decrease in urinary 3-methylhistidine/creatinine was significantly gr eater in the 6M group than in the 2M group. These results suggest that the lower frequency of meal intake leads to a greater myoprotein cata bolism even if the same diet is consumed.
