Summary of a study checking what happens with strength and strength endurance when a female athlete is rinsing their mouth with carbohydrate solution.
Who
16 resistance-trained females with 2 ± 1 years of experience aged 20 ± 1 years (Turkey).
Design
Randomised cross-over design
Low dose
- mouth rinsing with 6% carbohydrate solution
- for 10 seconds
Moderate dose
- mouth rinsing with 12% carbohydrate solution
- for 10 seconds
High dose
- mouth rinsing with 18% carbohydrate solution
- for 10 seconds
Water placebo
- liters rinsing their mouth with water
- for 10 seconds
Outcome measures
- muscular strength: bench press 1RM (1 repetition maximum)
- muscular ednurance: number of repetitions at 40% of 1RM bench press until failure
Main results
- rinsing mouth with different solutions of carbohydrate did not change strength nor strength endurance results in bench press performance.
- also, heart rate, glucose levels and RPE (rate of perceived exertion) did not differ between the solution of carbohydrate rinse
Take home message
For a clinician & coach
Rinsing mouth with different solutions of carbohydrate did not change strength nor strength endurance results in bench press performance. Also, heart rate, glucose levels and RPE (rate of perceived exertion) did not differ between athletes using different solutions of carbohydrate rinse.
For a parent
Rinsing mouth with different solutions of carbohydrate did not change strength nor strength endurance results in bench press performance.
For an athlete
Rinsing mouth with different solutions of carbohydrate did not change strength nor strength endurance results in bench press performance.
