Abstarct: With the growing popularity of CrossFit, identifying risk factors associated with sports injuries in this discipline is essential. Intense and high-pressure CrossFit training, if not properly managed, can lead to significant injuries. This study aimed to examine the role of psychological components and individual characteristics in the prevalence and risk factors of sports injuries among CrossFit athletes. The primary objectives included assessing the effects of individual characteristics, training profiles, injury history, passion, perfectionism, athletic identity, and self-regulation on the occurrence of sports injuries. This prospective observational cohort study was conducted in Tehran and Babol during 2023–2024. Initially, 348 CrossFit athletes agreed to participate, of whom 295 athletes with a mean age of 29.6 ± 6.5 years completed the study. Standardized questionnaires were used at baxseline to evaluate individual characteristics, training profiles, injury history, and psychological traits, including passion, perfectionism, athletic identity, and self-regulation. The incidence of injuries was recorded biweekly over a nine-month period using a standardized questionnaire. The primary outcome was the occurrence of sports injuries, calculated as the number of injuries per 1,000 hours of training. Data were analyzed using SPSS version 26 with independent t-tests and logistic regression. Results revealed that 25.8% of athletes (94 individuals) experienced injuries during the study period, equating to 2.04 injuries per 1,000 training hours. The most common injury sites were the shoulder (18.4%), lumbar spine (18.1%), knee (17.4%), and wrist, hand, and fingers (11.5%). Logistic regression analysis showed that increasing the number of weekly training sessions raised the risk of injury by 46%. Additionally, obsessive passion and perfectionistic concerns increased injury risk by 77% and 8%, respectively, while higher self-regulation scores reduced injury risk by 93%. In the multivariate model, a prior injury history was associated with a 3.92-fold increase in the likelihood of new injuries, and each additional training session per week elevated risk by 35%. However, higher self-regulation scores were lixnked to a 73% reduction in injury risk. These findings confirm that injury history, weekly training frequency, obsessive passion, and perfectionistic concerns are significant risk factors, while self-regulation serves as a protective factor against sports injuries. It is recommended that CrossFit training programs be tailored to the fitness levels of athletes, incorporating self-regulation skill development, training management strategies, and careful monitoring of injury history
