## 3 Results of Data Training and Discussion
### Interpretation of Coefficients  
Age: a positive coefficient of 0.0026624 suggests a slightly positive association between age and the outcome variable, although this association is relatively weak. Gender (male and female): both genders have significant negative coefficients (\(-6.7294\) for male and \(-6.6456\) for female), indicating that gender is not a significant factor influencing kinesiophobia. Injury: a positive coefficient of 0.94664 indicates a considerably positive association between the occurrence of injury and the outcome variable, suggesting that a previous injury increases the likelihood of kinesiophobia. Deceleration and overuse injuries: the negative coefficients for these specific types of injuries (\(-0.65269\) and \(-0.43516\), respectively) suggest that they do not contribute significantly to kinesiophobia, possibly due to perceptions of less severity or quicker recovery. Training hours and days: both variables have a positive coefficient (0.13735 and 0.080512, respectively), indicating a positive association with kinesiophobia, suggesting that more training time and greater frequency increase the risk of developing kinesiophobia. Overexertion: with a positive coefficient of 0.29543, overexertion is positively associated with kinesiophobia, possibly due to the higher likelihood of injury and physical exhaustion. Previous injuries: a positive coefficient of 0.030372, although weak, suggests that previous injuries may slightly influence kinesiophobia, perhaps due to fear of recurrence. Corrective and preventive treatments: while corrective treatment has a negative coefficient (\(-0.69206\)), indicating a possible reduction in kinesiophobia, preventive treatment has a positive coefficient (0.29251), suggesting that a perceived need for preventive treatment might be associated with higher levels of kinesiophobia. \begin{table}

Table 4: Model performance metrics. Sports with injuries: a negative coefficient of \(-0.6451\) indicates that participating in sports with a high incidence of injuries might be associated with lower levels of kinesiophobia, possibly due to greater familiarity with and management of injuries. Non-compliance: a positive coefficient of 0.8022 suggests that non-adherence to medical or training recommendations is positively associated with kinesiophobia. Stress injury and self-esteem injury: both factors have a negative coefficient (\(-0.4922\) and \(-0.26815\), respectively), indicating that better stress management and higher self-esteem related to injuries can reduce kinesiophobia. Fear and anxiety factors related to sports injuries: the variables \"fear of injury\", \"fear of pain\", \"fear of increasing pain\", \"fear of continuing sports with pain\", and \"fear of continuing training\" have high positive coefficients, indicating a strong positive association between these fears and kinesiophobia. This implies that individuals who experience greater fear of injury, pain, or continuing sports activities with pain are more likely to experience kinesiophobia.
