It appears that "carbohydrate loading" may enhance the performance of resistance training, but studies on CHO supplementation prior to a resistance-training bout are limited and have resulted in conflicting findings. PURPOSE: To investigate the effects of pre-exercise CHO supplementation on high-intensity (>75% 1RM) resistance training performance for resistance-trained women during an acute bout of resistance exercise. METHODS: Thirteen resistance trained female participants (21.9 ± 4.8 yrs; 64.5 ± 3.0 in; 137.0 ± 14.8 lbs) came to the Exercise and Performance Nutrition Laboratory on three separate occasions; the day of the Familiarization Trial (FT) and the two Exercise Testing sessions (ET1 and ET2, respectively) all separated by seven days. Familiarization testing determined each participant's 1RM of the bench press and leg press and then 75% of the bench press 1RM and 85% of the leg press 1RM was determined. The participants were then randomly assigned to either the CHO or P treatment session using a double blind, counterbalanced technique in a cross-over design with each participant consuming 1.0 g CHO/kg body weight or a non-caloric P beverage 60 minutes before beginning the exercise bout for each ET. The total volume of weight lifted during five sets of the bench press, the total volume of the weight lifted during five sets of the leg press, and whole body total lifting volume was analyzed by a two-way repeated measures within subjects ANOVA with significance set at P75% 1RM) resistance training sessions for women. During lower-intensity resistance training sessions, however, pre-exercise CHO supplementation may provide ergogenic effects and enhance resistance-training performance.
