Objectives: The aim of this study was to examine the effect of time of day on short-term repetitive maximal performance and psychological variables in elite judo athletes. Methods: Fourteen Tunisian elite male judokas (age: 21±1 years, height:172±7 cm, body-mass: 70.0±8.1 kg) performed a repeated shuttle sprint and jump ability (RSSJA) test (6×2×12.5 m every 25-s incorporating one countermovement jump (CMJ) between sprints) in the morning (7:00 a.m.) and afternoon (5:00 p.m.). Psychological variables (Profile of mood states (POMS-f) and Hooper questionnaires) were assessed before and ratings of perceived exertion (RPE) immediately after the RSSJA. Results: Sprint times (p〉0.05) of the six repetition, fatigue index of sprints (p〉0.05) as well as mean (p〉0.05) jump height and fatigue index (p〉0.05) of CMJ did not differ between morning and afternoon. No differences were observed between the two times-of-day for anxiety, anger, confusion, depression, fatigue, interpersonal relationship, sleep and muscle soreness (p〉0.05). Jump height in CMJ 3 and 4 (p〈0.05) and RPE (p〈0.05) and vigor (p〈0.01) scores were higher in the afternoon compared to the morning. Stress was higher in the morning compared to the afternoon (p〈0.01). Conclusion: In contrast to previous research, repeated sprint running performance and mood states of the tested elite athletes showed no-strong dependency of time-of-day of testing. A possible explanation can be the habituation of the judo athletes to work out early in the morning.
