Abstract
Intermittent sport athletes such as soccer players succumb to fatigue in the latter stages of a match. This study compared the effects of calorically matched 6% carbohydrate (CHO) and 6% carbohydrate + 1.5% protein (CHO+PRO) sports drinks on prolonged high intensity intermittent running performance in adolescent soccer players. Seven male high school soccer players participated in 3 randomized, cross over experimentally designed trials. A laboratory-based, soccer-specific running protocol was implemented for 60 min interspersed with 3 min recovery periods every 15 min. A subsequent run to fatigue at 55% and 95% VO2max was performed at the end of 60 min. Participants randomly ingested placebo (PLA), 6% CHO, or 6% CHO + 1.5% PRO immediately before exercise every 15 min rest period and immediately before the run to exhaustion. No significant differences were found between trials at time to exhaustion run time (s) (PLA 966.8±503.8, CHO 919.0±759.9, CHO+PRO 1032.7±648.7), blood glucose (BG) (PLA 90.7±4.7, CHO 98.1±4.7, 97.4±4.7 mmol/L), or rating of perceived exertion (RPE) (PLA 17.7±0.4, CHO 17.4±0.4, CHO+PRO 17.3—0.4) (p < 0.05). These findings suggest that when CHOs are ingested at optimal rates, adding a moderate amount of PRO to a CHO beverage does not enhance latter match intermittent running performance in adolescent soccer players.
