Injury and Fitness Outcomes during Implementation of Physical Readiness Training

摘要

This study examined injury and physical fitness outcomes in Basic Combat Training (BCT) during implementation of Physical Readiness Training (PRT). PRT is the U.S. Army's emerging physical fitness training program. An experimental group (EG, n = 1,284), which implemented the PRT program, was compared to a control group (CG, n = 1,296), which used a traditional BCT physical training program during the 9-week BCT cycle. Injury cases were obtained from recruit medical records and physical fitness was measured using the U.S. Army Physical Fitness Test (APFT, consisting of push-ups, sit-ups, and a two-mile run). Injury rates were examined using Cox regression after controlling for initial group differences in demographics, fitness, and other variables. Compared to the EG, the adjusted relative risk of a time-loss overuse injury in the CG was 1.5 (95% confidence interval CI) = 1.0-2.1, p.
