Incidence of Sports Injury in Middle and High School Fencers by Gender, Grade and Type during Training. The Journal of Kinesiology, 2017, 19(4): 65-72. [PURPOSE] The purpose of this study was to provide basic data for prevention of injuries by understanding the sports injury status of middle and high school fencers. [METHODS] The subjects were 399 middle and high school fencers. Survey was classified as injury rate, injured site, tissue and plans of injury prevention during training. The collected data were analyzed by frequency analysis, x2 tests and two-way ANOVA using the spss program to identify differences in gender, grade, and type. [RESULTS] The results of this study were as follows: First, female fencers (p <.011) and high school fencers (p <.000) experienced statistically significant injury than male and middle school fencers. The incidence of injury per training hour was significantly higher female fencers than male fencers (p <.035) in middle school. Second, the injury of ankle was the highest rate in total groups (18.22%), and the injured tissues were muscles (27.46%) and ligaments (27.27%) were the highest injury rate in total groups. Third, plans of injury prevention showed that the warm up and cool down were the highest rate (38.96%) in all total groups. [CONCLUSIONS] These results suggest that development of specific warm-up and cool-down program and ankle strengthening exercise should be studied to prevent injuries for middle and high school fencers, particularly female fencers should be more careful in preventing injuries.
