Research Presentation Abstract

To examine effects of carbohydrate supplementation in liquid and bean form on performance, perceived exertion, and gastrointestinal response during repeated maximal effort sprints in collegiate female swimmers. Sixteen swimmers performed 6 x 100 yard sprints on three occasions. Participants were randomly grouped to determine supplement order (0.36 g/kg CHO in bean, liquid, or liquid placebo form). Supplements were divided into 5 portions and consumed after each 100-yard sprint. Perceived exertion, gut discomfort and fullness, and timed performance were recorded after each sprint. Average gut fullness and discomfort were significantly higher in liquid forms compared to bean (p < 0.05). No significant differences were found in average RPE or timed performance between supplements (p > 0.05). Results suggest a CHO bean may be more appropriate to minimize gut fullness and discomfort during training.

The Effects of CHO Supplementation Form on RPE, Timed Performance and Gastrointestinal Response in Collegiate Female Swimmers

To examine effects of carbohydrate supplementation in liquid and bean form on performance, perceived exertion, and gastrointestinal response during repeated maximal effort sprints in collegiate female swimmers.
