Abstract

The purpose of this study was to determine the effects of carbohydrate refeeding on intermittent sprint exercise, blood lactate response, and mood following a typical weight-reduction program practiced by college wrestlers. Fifteen collegiate wrestlers from the University of Northern Iowa completed 3 trials of intermittent arm cranking and a mood inventory prior to weigh-ins (baseline), after weigh-ins, and 1 hour post consumption of either 1.5 g carbohydrate (CHO)/kg body mass carbohydrate beverage (25% solution) or placebo taken within 1 hour after weigh-ins. Blood lactate responses were determined with each trial. Repeated measures analysis of variance indicated no significant interaction between group and trial for total work (p = 0.08), blood lactate (p = 0.29), positive mood (p = 0.49), or negative mood (p = 0.78). Simple effects analysis indicated a significant difference in lactate response between trials (p = 0.002); however, no difference for work (p = 0.75), positive mood (p = 0.13), or negative mood (p = 0.08). The results of this study suggest that intermittent sprint exercise, blood lactate response, and mood were not positively affected by ingestion of CHOs following an acute weight-reduction period.
