Abstract:Caffeine has been shown to increase aerobic and anaerobic performance especially in elite level athletes. Recently, caffeine mouth rinsing without ingestion has had same ergogenic potential with ingestion in some performance parameters. The purpose of this study was to investigate serial rinsing of caffeine during the warm-up period before wingate anaerobic test (Want) performance. Ten physically active male completed the following 10-s mouth rinsing protocols; a-) %2 w/v caffeine solution (Caf) b-) water (Pla) c-) no rinse as a control (Con) with a randomised, double-blind, crossover and counterbalanced research design. Serial mouth rinse protocol was implemented (8x25 ml solutions at 30-s intervals during 5 minutes warm up). Following to last rinse, participants were asked to cycle 30-s maximal sprint on a cycle ergometer. Peak and Mean power output were calculated via cycle ergometer software, also at rest and immediately after Want, heart rate (HR) and rating of perceived exertion (Rpe) were assessed. In comparison with Pla and Con, Caf trial had no significant effect on peak (p>0.05) and mean (p>0.05) power output, there were also no significant effects on heart rate and ratings of perceived exertion (p>0.05).

Öz: Kafeinin, aerobik dayanıklılık performansı üzerine etkisi bilinmektedir fakat anaerobik güç üzerine etkisini inceleyen çok az çalışma mevcuttur ve sonuçlar birbiri ile farklılık göstermektedir. Ayrıca, son yıllarda kafeinli kahve ve toz kafeinin aerobik ve kassal kuvvet performansları üzerine etkilerinde farklılık olmadığını gösteren çalışmalar mevcuttur. Bu çalışmanın amacı, düşük doz kafeinli kahvenin fiziksel olarak aktif erkeklerde 30 saniyelik wingate anaerobik test (Want) performansına etkisinin incelenmesidir.
