[email protected] Abstract Circadian rhythm is a 24-hour psychological and physiological fluctuations. The present study examined the effect of circadian rhythm on several physical and physiological parameters in male taekwondo athlete. For the circadian rhythm, daily time period was divided in hours as 08 30-1030, 1130-1330, 1430-1630, 1730-1930, 2030-2230. Athletes chronotypical structures and sleep qualities were determined by Horne-Ostberg’s MorningnessEveningness Questionnaire and Epworth Sleepiness Scale. Nine male athlete (age 19,22±1,9 year, stature 176,9±3,9 cm, body mass 66,9 ±11,9 kg) participated in this study. The athlete’s resting heart rates, intra-aural resting body temperatures were measured and counter movement jump test, paldeung technique effect level test and Wingate anaerobic power and capacity test were applied. The normality assumption of the data was examined by Shapiro-Wilks test. Time periods were compared using analysis of variance (ANOVA) followed by a LSD post-hoc test. Pearson correlation coefficient analysis was used to examine the relations between variables. Value of significance was accepted as p
