By analyzing the reasons, and doing the countermeasure analysis, compare the specific effect. Results: through the analysis of the training injury, 13 cases, 8 cases, 8 cases, 4 cases, 3 cases, t=5.096,7.035,4.832,3.621, p <0.05. The quality of mental, daily life, society, psychological ± 3.3,68.4 ± 2.5,20.2 ± 2.4,68.5 ± 2.2, respectively. The overall situation improved significantly after prevention (p <0.05).By comparing the satisfaction of patients before and after prevention, prevention was prone to training injury, satisfaction was 66.3 ± 3.7 points, training injury significantly decreased, the satisfaction score was 92.2 ± 2.1, with certain differences (t=12.565) p <0.05. Conclusion: analyze the causes of army training injury and give some countermeasures.展开更多
