Popis: Many bodybuilders attempt to lose large amounts of weight in short periods of time through the use of low energy diets. Research suggests that consumption of a low energy, low carbohydrate diet may negatively affect mood states. Further research suggests that carbohydrate consumption can positively affect mood states. This study evaluated two main ideas: (1) does the consumption of a carbohydrate supplement affect mood states during weight training bouts and (2) does carbohydrate supplementation affect perception of effort of a weight training bout. Male weightlifters (N=17) consumed a low energy diet for four days (21 kcal/kg body weight). On the fifth day, the weightlifters consumed either a carbohydrate beverage ( "Sports Shot" at 1.15 gm CHO/kg bw) or a placebo beverage ( "Challenge" at 1.06 gm protein/kg bw) before testing was started. The subjects filled out a Profile of Mood states (POMS) questionnaire fifteen minutes prior to and immediately after a bench press exercise test. The flat bench press exercise test consisted of lifting 7 sets of decreasing repetitions at 60% of their maximum lift with the final set continuing until volitional fatigue. Ratings of Perceived Exertion (RPE) were recorded between each set. Data were analyzed by three-way ANOVA. The carbohydrate group had a significantly (p
