This study aimed to College Students Majoring Police of Police Martial Arts Education on Body composition and Physical Fitness on Job Performance. Eighty voluntary subjects (40 exercise, 40 control) with an understand-ing toward the aims of this study were selected and their physical composition and Physical Fitness on Job Per-formance, before and after the Police Martial Arts Education program, were measured. As for the physical composition, there were significant differences between pre- and post-values in the exer-cise group after completing the police Martial Arts Education. The change in physical composition has shown a significant change in EG group to weight, skeletal muscle mass, BMI, body fat percentage statistically and the physical composition has shown a significant change in CG group to skeletal muscle mass, BMI, body fat percent-age statistically. Also, at the preliminary inspection between two different groups according to police military training, every variable of physical composition no significant difference was shown statistically, and at the post inspection, BMI, body fat percentage the significant difference was shown statistically. As for the Physical Fitness on Job Performance, there were significant differences between pre- and post-values in the exercise group. The change in physical variable in EG group has shown significant change in every variable such as grasping power in left hand, grasping power in right hand, sit-up, push-up, 100m, 1000m statistically, and the change in physical variable in CG group has shown significant change in grasping power in right hand statistically. Also, at the pre-liminary inspection between two groups according to the police military training has not shown a significant change in every variable, however, at the post inspection, a significant change has shown in every variable. The study results indicate that the Police Martial Arts Education program is effective in improving the Body composition and Physical Fitness on Job Performance of College Students Majoring Police. However, there is a need for more specific exercise programs to be developed for the continual improvement of College Students Majoring Police performance in along with further studies to confirm the physiological benefits of those programs.
