Introduction: Physical training-related musculoskeletal injuries are a major problem in military populations. The purpose of this study was the determination of the most common sites of musculoskeletal injuries and the relationship between sports history and musculoskeletal injuries during the course of six month police military exercises.

Materials and Methods: During a prospective cohort study, data on musculoskeletal injuries of 150 male police students during the course of six month police military exercises were obtained. Their demographic characteristics and previous sports history have been evaluated. Data on incidence of musculoskeletal disorders was collected from Nordic questionnaire during the course of six month police military exercises. The incidence of the most common sites of musculoskeletal injuries was calculated as percentage of the total study population and the X² test and fisher exact test were used to determine the relationship between sports history with musculoskeletal injuries.

Results: Among 150 enrolled male recruits the most common sites of musculoskeletal injuries were knee (45.4%), Low back (30.7%) and ankle (17%). Also, the incidences of musculoskeletal injuries in persons with or without previous sports history were 57.5% and 63.6% respectively.

Conclusion: Lower extremity and low back injuries were the most common sites of musculoskeletal injuries during the course of six month police military exercises. Also, the pervious sports history of participants and their probable higher physical fitness may be considered as a protective factor in development of musculoskeletal disorders.
