Purpose: The emptiness of carbohydrate (CHO) in the mouth empty creates increases in performance, especially in resistance. The mechanisms responsible for this ergogenic effect may be associated with the receptors in the mouth empty that detect CHO, so the motor unit can increase the nerve stimulation. The aim of this study is to explore the effects of choking in the mouth on the interval sprint performance in footballers. With randomized, double-blind, cross-circular, mutual balanced research design, 15 amateur footballers (medium±SD age: 20,00±2,44 years, length: 177,66±4,80 cm, body weight: 75,02±6,42 kg) completed the protocol consisting of 12x4 seconds interval sprints in a total of 3 times before each sprint [a-) 6.4 % carbohydrate solution (CHO) b-) plasebo (PLA) and c-) controls (CON) 10 seconds without swallowing in the mouth. In the rest, immediately after the test, the active and passive recovery recorded blood glucose (GL), blood lactate (BL), heart rate (HR) and detected difficulty degree (RPE). Results: Compared to CON, there were significant increases in CHO and PLA top and average power data but there was no difference between CHO and PLA. While the BL and BG values did not make a difference between the conditions (P>0.05) HR values were significantly different in the CON condition according to CHO and PLA. Furthermore, a significant difference was found from PLA in the RPE CON condition but no difference was found with the CHO condition. The result: CHO in the mouth, compared to PLA, does not develop the peak and average power, but as a nosebo effect, it develops the peak and average power according to CHO and PLA CON.
