Abstract

The study examined the synergistic and independent effects of carbohydrate-caffeine mouth rinse onrepeated sprint performance during simulated soccer match play. Nine male soccer players (21 ± 3 years,1.75 ± 0.05 m, 68.0 ± 9.0 kg) completed four trials with either 6 mg·kg−1 caffeine + 10% maltodextrin (CHO+CAFMR), 6 mg·kg−1 caffeine (CAFMR), 10% maltodextrin (CHOMR), water (PLA) in a block randomised,double-blinded, counterbalanced and crossover manner separated by minimum 96 h. All solutions weretaste-matched and a carbohydrate-rich meal (2 g·kg−1body mass) was provided 2 h before each trial. Eachtrial consisted of a 90-min soccer-specific aerobic field test (SAFT90) and two bouts of repeated sprintability tests (RSAT; 6 × 6 s sprints with 24 s recovery) completed at 0 min and 75th min of SAFT90. A 25 mlsolution of either CHO+CAFMR, CAFMR, CHOMR or PLA was rinsed immediately before the second RSAT(75 min). Mean power output, peak power output (PPO) or fatigue index (FI) was not impacted by anytreatment during the 75th min RAST (p > 0.05). These results suggest that carbohydrate and/or caffeinemouth rinses do not have an ergogenic effect during simulated soccer exercise after a high carbohydratemeal.
