Background: The purpose of this study was to consider the effects of Selected Program of Basic Preparation on the prevalence of common physical injuries in students of Amin University of Police. Materials and Methods: 300 preparatory 2010 male students of Amin University of Police were purposefully selected and randomly divided into two groups of experimental (n = 150) and control (n = 150) with the following means and standard deviations age: 19.62 ± 1.03 (years), height 176.57 ± 4.69 (cm), and weight 66.26 ± 6.63 (Kg). Injury questionnaire was used for data collection. Selected and Common programs of Basic Preparation were carried out under the supervision of a trainer for eight weeks. Obtained data were statistically analyzed through t Test at significance level of P ≤ 0.05. Results: The results showed that lower body with 54.61% more than other parts of the body of the study samples had been injured during training and muscles with 63.13% more than other parts had been exposed to injury. The lower extremities with 57.41, 43.95, 57.64, 56.56 percent, respectively, involved the most common injury to the bone, skin, muscle and joint accounts during training. In addition, common skeletal upper body injuries (P = 0.013), common skeletal trunk injuries (P = 0.003), common skeletal lower body injuries (P < 0.001), common muscular upper body injuries (P < 0.001), common muscular trunk body injuries (P < 0.001), common muscular lower body injuries (P < 0.001), common joint upper body injuries (P = 0.001), common joint trunk body injuries (P < 0.001), common joint lower body injuries (P < 0.001), were significantly reduced subsequent to the termination of the selected training program. Conclusion: The results suggest that the lower extremities have been injured more than other parts of the body during training. Also, compare to common programs, probable risk of students' injury in Selected Program of Basic Preparation is less, which requires more attention of the Country's military high-ranking officials in applying the Selected Program of Basic Preparation.
