摘要:The purpose of thisstudy was to investigate the effects of circadian rhythm on anaerobicperformance and body temperature determinedthrough three different methods. Ten elite male taekwondo athletes (averageage: 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 weremeasured in the morning of the first day, (between 09:00-10:00 a.m.), and inthe early evening (between 16:00-17:00 p.m.) through three different methods (Corebody temperature, tympanic temperature, and skin surface temperature). Theparticipants performed Wingate test (WT) both in the morning and in the earlyevening. Core body temperature was significantly higher in early evening than itwas in the morning (p0.05). However, there was no significant difference between morningand early evening for peak power, mean power, and fatigue index values(p>0.05). As a result, a significant increase was observed in core body temperaturein early evening compared to morning, but this increase did not show a positiveeffect on anaerobic performance.
