Abstract :The purpose of this study was to investigate the effects of circadian rhythm on anaerobic performance and body temperature determined through three different methods. Ten elite male taekwondo athletes insert ignore into journalissuearticles values(average age: 23.9±2.7 years, height: 178.7±4.9 cm, body mass: 72.1±7.8 kg, training experience: 12.5±4.9 years); participated in the study. The body temperatures of the participants were measured in the morning of the first day, insert ignore into journalissuearticles values(between 09:00-10:00 a.m.);, and in the early evening insert ignore into journalissuearticles values(between 16:00-17:00 p.m.); through three different methods insert ignore into journalissuearticles values(Core body temperature, tympanic temperature, and skin surface temperature);. The participants performed Wingate test insert ignore into journalissuearticles values(WT); both in the morning and in the early evening. Core body temperature was significantly higher in early evening than it was in the morning insert ignore into journalissuearticles values(p<0.05);, while tympanic and skin surface temperatures remained unchanged insert ignore into journalissuearticles values(p>0.05);. However, there was no significant difference between morning and early evening for peak power, mean power, and fatigue index values insert ignore into journalissuearticles values(p>0.05);. As a result, a significant increase was observed in core body temperature in early evening compared to morning, but this increase did not show a positive effect on anaerobic performance.
