Abstract:
Introduction: Carbohydrate (CHO) mouth rinsing can enhance sports performance
through a central action mediated by receptors in the mouth. This study examined the effect of a
CHO mouth rinse on salivary lysozyme concentrations, mood states and running performances.
Methods: Ten males recreational runners were randomised to three running trials with a
1 week recovery period between the trials. Each trial involved running at 75% maximum heart rate
(HRmax) for 1 h, followed by a 15 min time trial. The participants used a CHO mouth rinse, placebo
(PLA) solution or control (CON, no solution) every 15 min during the exercise. Heart rate (HR),
rating of perceived exertion (RPE) and mood states were recorded pre-, during and post-exercise.
Saliva samples were collected pre-, post- and 1 h post-exercise.
Results: There was no significant interaction and time effect (P > 0.05) on the salivary
lysozyme concentration and running performance, but it was significant (P < 0.05) for HR and RPE
(increase in all trials). However, there was no significant difference (P > 0.05) in salivary lysozyme
concentrations, running performances, HR values or RPE between the trials. Mood states were
not significantly different (P > 0.05) between the trials, but one of the mood sub-scales showed a
significant (P < 0.001) time effect (increase fatigue in all trials).
Conclusion: CHO mouth rinsing did not affect physiological parameters, salivary lysozyme
concentrations, mood states or running performance among recreational runners.
