Hypothesis
A carbohydrate mouth rinse would affect endurance capacity in a nonathletic population and would have more effect in the fasted state compared to the fed state.
Conclusion
Carbohydrate mouth rinsing improves endurance capacity in both fed and fasted states in non-athletic subjects.
Supporting Evidence
- Mouth rinsing with maltodextrin improved time-to-exhaustion in both pre- and postprandial states.
- This improvement was accompanied by reductions in perceived exertion.
- The ergogenic effect was more evident in the fasted state.
Takeaway
Rinsing your mouth with a sugary solution can help you exercise longer, even if you just ate or if you haven't eaten.
Methodology
13 healthy non-athletic males performed 5 tests on a cycle ergometer, rinsing their mouth with either a maltodextrin solution or water while cycling until exhaustion.
Potential Biases
Potential for experimenter bias due to the single-blinded design.
Limitations
The study was single-blinded, which may introduce bias, and the sample size was small.
Participant Demographics
13 healthy non-athletic male subjects, average age 21 years.
