Abstract

Purpose: To examine whether the use of a carbohydrate mouth rinse (CMR) can improve multiple choice reaction time (MCRT) in amateur boxers during sparring.

Methods: Eight male amateur boxers (age 22 ± 3 years, stature 1.78 ± 0.07 m, mass 73.6 ± 14.2 kg) with at least 18 months experience in the sport volunteered. All participants attended a familiarisation session, followed by an experimental (CMR; 6% dextrose) and placebo (PLAC) trial completed in a random order. Participants undertook 3 x 2-min of sparring against an ability and size (stature and mass) matched opponent. MCRT and perceived exertion was measured before round 1, and then after each round. The respective mouth rinse was administered in a 25-ml solution for 10-s before each round. Magnitude based inferences were used to compare the results from each round (mean difference ± 90% confidence limits).

Results: The CMR was unlikely to have a beneficial effect on MCRT compared to PLAC (5 ±9.5, 4 ±3.4, -1 ±8.5 lights for each round respectively), and had a possibly harmful effect on perceived exertion in round one (10 ±20). There was an unlikely harmful effect on perceived exertion in rounds two (1 ±12) and three (9 ±23).

Conclusions: There is no evidence to support the use of CMR during sparring in amateur boxers.
