About this trial
This observational study aims to investigate the prevalence of musculoskeletal injuries and cardiovascular risk factors among individuals with and without exercise addiction. Adult recreational gym users who have been engaging in resistance training for at least six months will be included. Participants will be divided into two groups based on their exercise dependence levels, and outcomes such as musculoskeletal symptoms, anabolic substance use, and cardiovascular risk scores will be compared between groups.

Trial population
The study population will consist of healthy adult individuals aged 18 years or older who are members of fitness centers in Istanbul and have been regularly engaging in resistance or bodybuilding training for at least six months. All participants must exercise at least three times per week and meet the inclusion criteria. Individuals will be divided into two groups based on their exercise dependence status: those who meet the criteria for exercise addiction and those who do not. Participants with professional athletic status or a diagnosed psychiatric illness will be excluded. The population represents recreational gym users with varying attitudes toward exercise behavior, body image, and supplement use, providing a real-world sample for assessing the musculoskeletal and cardiovascular impacts of exercise addiction.

Battery of Physical and Psychological Assessments
Other interventionParticipants in this observational study will not receive any therapeutic intervention. Instead, all individuals will undergo a series of standardized non-invasive assessments for data collection purposes. These include the Exercise Dependence Scale-21 (EDS-21) to classify exercise addiction status, the Drive for Muscularity Scale (DMS) to evaluate body image and muscle-related attitudes, and the Extended Nordic Musculoskeletal Questionnaire to determine the presence and severity of musculoskeletal symptoms. Cardiovascular risk will be assessed using the SCORE Risk Assessment System, which incorporates blood pressure, cholesterol, blood glucose, smoking status, and demographic data. Additional measurements will include oxygen saturation and heart rate using pulse oximetry, and blood pressure using a sphygmomanometer. These evaluations are intended solely for comparative analysis between exercise-dependent and non-dependent groups.
