The effect of resistance training on injury rate and performance in a self-defense instructors course for women

This study examined the effect of a resistance training (RT) program on injury rate and performance in a 10-week self-defense instructors course for women (n = 28). Thirteen subjects were assigned to RT while the other 15 were involved in a running program. Subjects were assumed to be randomly distributed between both groups. The 1-RM strength in bench press (BP) and squat were measured pre and post. Injury rate was determined by number of medical complaints relating to the course, and through pain/soreness questionnaires at post. Self-defense performance was evaluated in skill and technique (S&T), instructional ability (IA), and 2 types of combat tests: F1 and F2. Total score was also computed. Strength improved in RT for both BP and squat. Only BP strength differed significantly between groups at post. RT scored higher in total score, IA, and F1. Although there were no significant differences in injury rate or pain/soreness between groups, RT had a consistent trend for reduced incidence of pain and injury. Also, significant correlations were seen between 1-RM BP and total score, IA, S&T, and F2. Results suggest RT may enhance self-defense performance and instructional ability and reduce the incidence of pain and injury during a self-defense course.
