The purpose of this study was to examine the effects of time of day on technical and physical performance parameters in young female tennis players. A sample of 12 recreational tennis players (age 24.2 +/- 3.8 years) were randomly distributed into two groups. After having their demographics (age, experience, chronotypes), they were measured for body mass, body temperature, serve accuracy, serve speed, countermovement jump, grip strength, agility, and linear speed by counterbalancing method on two different days and at two different times of the day (09:00 and 16:30). The main results revealed that the players had significantly (p < 0.01) higher body temperature and greater values in the grip strength test during the afternoon session in comparison to the morning session. On the other hand, no significant differences (p > 0.05) were observed for other physical and technical performance parameters. The findings may highlight that time of day has no significant effects on several tennis-related performance determinants in female recreational players.
