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. Armys 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 0.0l for men and 1.4 95 CI 1.1-1.8, p 0.01 for women. There were no differences between groups for traumatic injuries. On the first administration of the final APFT, the EG had a greater proportion of recruits passing the test than the CG men 85 vs. 81 , p 0.04 women 80 vs. 70, p 0.01. After all APFT retakes, the EG had significantly fewer APFT failures than the CG among the women 1.6 vs. 4.6, p 0.01, but not the men 1.6 vs. 2.8, p 0.18 the gender-combined EG had a higher pass rate 1.6 vs. 3.7, p 0.01. In summary, the PRT program resulted in a lower risk of overuse injuries, higher first time pass rate on the APFT, and a lower rate of APFT failure when compared to traditional physical training in BCT. These outcomes suggest that the PRT program should be employed in all BCT units.
