Caffeine vs. Carbohydrate Mouth Rinsing in Soccer

The present study evaluated the influence of carbohydrate mouth-rinsing (CHO-MR), caffeine mouth-rinsing (CAF-MR), and control-substance mouth rinses on Loughborough soccer passing test (LSPT) performance. The study participants were involved in a randomized, double-blind, repeated-measures design that employed four sessions (familiarization, CHOMR, CAFMR, and CONT) over ten days at a testing facility. Participants took part in six test sessions 72 hours apart. In the CHO group, 6% w/v glucose solution was used. In the CAFF group, 6% w/v glucose solution was used. CONT group, only exercise was performed without any condition.
