Several metabolic changes caused by regular exercise, can lead to adaptive mechanisms in athletes. These changes create a new dynamic balance that ensures better performance. On the other hand, because most studies on changes in the metabolic profile of the blood have been conducted in male athletes, this study investigated the effects of different exercise conditions on reactive oxygen species (ROS), adiponectin, and subjective mood in female athletes. A cohort of 30 females, 20 professional players (10 target shooters and 10 basketball players), and 10 sedentary females as control group were enrolled in the study. Capillary blood samples and the Brunel Mood Scale questionnaire (BRUMS) were collected at noon before the training session. ROS and adiponectin were determined by the ELISA method. To compare among groups, one-way analysis of variance and Tukey's post hoc test were used at the significance level of P<0.05. Physiological evaluations showed a significant high level of adiponectin in basketball players (p=0.005). The anger subscale in the basketball group had a significant increase compared to other groups (p=0.04). The tension subscale exhibited a higher level in the shooting group than in the control group. (p=0.017). Regarding the vigor subscale, there was no significant difference in experimental groups, and there was a significant difference in the non-athlete group (control) (p=0.001). Basketball, being a team sport, exhibits a greater degree of aggression in contrast to shooting, which is classified as an individual sport. More focus of coaches on adjusting in another sport with non-competitive and non-confrontational features to reduce anger is suggested.
