The present study was aimed at demonstrating the effects of ingestion of carbohydrate solution (maltodextrin; 1.5g/kg) immediately after exercise during body weight reduction on body composition, physical working capacity (maximal anaerobic power), and subjective symptoms of the sensual fatigue (SF) in 6 male members of Tokai university Judo team. Results showed that the percentage of decrease in B. W. (weight during training-weight during reduction/weight during training×100) was significantly (r=0.87,p<0.01) correlated with the amount of decrease in lean body mass (LBM, training period-reduction period). The average energy intake per day was 2636 kcal in first one week and 1849 kcal in last one week during the weight reduction, a difference of energy intake was 787 kcal per day. The average weight reduction was 3.7 kg in body weight, and the loss in the body fat was greater than that in the lean body mass (LBM). The meximal anaerobic power was no tendency to decrease during weight reduction. The level of SF had unremarkable changes during weight reduction. It is thus suggests that ingestion of carbohydrate (maltodextrin solution) immediately after exercise during body weight reduction may be effective to prevent loss in LBM and physical capacity, and it also might be useful in the weight control of the Judo athletes.
