Investigation and analysis on ankle injury of officers and soldiers induced by 5 km armed cross-country training

Objective To investigate the ankle injury situation of officers and soldiers in the 5 km cross-country armed training and its related influence factors.Methods 827 officers and soldiers accepted 5 km armed cross-country training from January 2010 to December 2011 were selected as research objects,then the number of ankle injuries,location,influence factors and the partial correlation coefficient among these factors were investigated and analyzed.Results Among 827 officers and soldiers,the right ankle injury rate was the highest and it was 9.07%.The rate of ankle injury in officers and soldiers with insufficient preparation and less training times were 26.01% and 26.67%,which were higher than others(P ￡? 0.05).The fatigue degree of officers and soldiers with ankle injury was 4.9857 points,it was higher than that without ankle injury(P ￡? 0.05).The factors of preparation situation,training methods and means,training times and individual differences were related to the ankle injury(all P ￡? 0.05).Conclusion The right ankle injury is the main injury of 827 officers and soldiers induced by 5 km armed cross-country training,while,the factors of preparation situation,training methods and means,training times and individual differences are related to ankle injury.
