Physical training risk factors for musculoskeletal injury in female solders

[摘要] Musculoskeletal injuries result in the most medical encounters, lost duty days, and service members on permanent disability.Women are at greater risk of injury than men and physical training is the leading cause of injury.The purpose of this study is to investigate the demographic, body composition, fitness, and physical training risk factors for injuries in female soldiers serving in operational Army units over the past 12 months. Self-report survey was collected from 625 women.Correlation, chi squared, relative risk, and logistic regression were used to analyze the results.The ankle was the most frequently injured body region, 13%.Running was the activity most often associated with injury, 34%.In univariate analysis rank, age, history of deployment, weekly frequency of unit runs, weekly frequency of personal strength training, and history of injury were all associated with injury.Having the rank of private to specialist increased the relative risk (RR) of injury by 68%, being in the Blue Brigade increased the RR by 48%, having no history of deployment increased the RR by 48%, having a history of injury in the last 12 months increase the RR by 160%, having no weekly unit runs increased the RR by 53%, having a weekly frequency of 1-2 personal weight training sessions increased RR by 42%,having a run time between 17 and 18 minutes increased RR by 71%, and having an Army Physical Fitness Score below 290 increased RR at least 70%.In multivariate analysis rank, history of injury, weekly frequency of unit runs, and weekly frequency of personal strength training were the best combination of predictors of injury in female soldiers.Running once or twice a week with the unit protected against MSI while participating in personal strength training sessions once or twice a week increased the risk of MSI.Fitness was neither protective nor harmful when all other variables were accounted for in the equation.The public health significance is that with a higher emphasis on running and strength training, the US Army could reduce injuries and save billions of dollars in training and healthcare costs.
