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 (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, (between 09:00-10:00 a.m.), and in
the early evening (between 16:00-17:00 p.m.) through three different methods (Core
body temperature, tympanic temperature, and skin surface temperature). The
participants performed Wingate test (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 (p<0.05), while tympanic
and skin surface temperatures remained unchanged
(p>0.05). However, there was no significant difference between morning
and 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 temperature
in early evening compared to morning, but this increase did not show a positive
effect on anaerobic performance.
