Physical Fitness and Body Composition After a 9-Month Deployment to Afghanistan
Abstract
To examine change in physical fitness and body composition after a military deployment to Afghanistan. Methods: one hundred and ten infantry soldiers were measured before and after a 9-month deployment to Afghanistan for Operation Enduring Freedom. Measurements included treadmill peak oxygen uptake (peak VO2), lifting strength, medicine ball put, vertical jump, and body composition estimated via dual-energy x-ray absorptiometry (percent body fat), absolute body fat, fat-free mass, bone mineral content, and bone mineral density. Results: There were significant decreases (P<0.01) in peak VO2 (-4.5%), medicine ball put(-4.9% body mass {-1.9%}, and fat-free mass{-3.5 %}, wheras percent body fat increased from 17.7% to 19.6%.
