Context: The level of body awareness, performance emotional state (PES), and demographic characteristics in different sports are subjects to be investigated. It is important to examine the concepts of PES and body awareness to better understand the body-mind relationship in different sports. Objective: The aim of this study was to investigate the level of body awareness and PES of athletes. Design: In this cross-sectional study, the independent variables are groups (4 different sports). and the dependent variables are body awareness and PES. Participants: The study was conducted on 188 licensed athletes (85 footballers. 36 basketball players, 34 handball players, and 33 swimmers). The mean age of the participants was 14.64 (1.89) years, mean height was 172.44 (11.03) cm, and mean body weight was 62.35 (13.12) kg. Settings: Four sports clubs and 2 high schools were the intervention facilities. Intervention: Body Awareness Questionnaire and Continuous Optimal Performance Emotional Status Scale-2 were used for data collection. Sociodemographic information was recorded. Main Outcome Measures: One-way analysis of variance was used for analysis of normal distribution data in 4 different groups, and the Kruskal-Wallis test was used for the analysis of data that did not show normal distribution. Results: There was no difference in body awareness among the branches (P = .17). The PES of the footballers was better than that of other athletes (P = .01). The correlation between body awareness and PES was medium (r= .47, P < .01), and the correlations between body awareness and age, licensed year, and number of weekly training sessions were weak (r= .22, P < .01; r= .19. P < .01; r= .15, P = .03). Conclusions: The body awareness of athletes may not differ among different sports, but PES is related to many factors such as mood, age, license years. and number of training sessions. In rehabilitation and training, body awareness and PES should be evaluated together.
