The purpose of this study is to investigate the relationship between injuries, physical strength, and physical composition of prospective Air Force cadets, and to provide basic data for preventing injuries in cadet life and fostering effective aviation physical strength in the future. a survey of 198(male 180, female 18) first-year cadets for three months before Physical Activity Survey, body composition, physical strength evaluation and basic military training to investigate the current status and relationship of musculoskeletal injury records during basic military training. The main conclusions through the derived research results are as follows. First, as a result of physical composition analysis, there was no statistically significant difference between male and female prospective students in both the injured and non-injured groups. However, in BMI, the non-injury group tended to be high. Second, as a result of the physical fitness evaluation analysis, there was no statistically significant difference between male and female prospective students in both the injured or non-injured groups. Third, as a result of the analysis of the physical activity survey, male prospective students showed a statistically significant difference in the number of high-intensity exercises, and prospective female students showed a statistically significant difference in the number of high-intensity exercises and high-intensity exercise time. It was concluded that if physical activity was repeated with high intensity, it could be expected to improve the physical fitness factor, which could lower the risk of injury. It is necessary to gradually increase the amount of physical activity before training for prospective cadets entering basic military training to reduce the risk of injury and help them live a healthy cadet life with successful training fees.
