The Victory Fitness VF Program examined fitness and injury outcomes during the initial toughening phase of Physical Readiness Training PRT. PRT is the U.S. Armys emerging physical training doctrine. A Basic Combat Training BCT battalion which implemented PRT VF battalion, n 1284 was compared to a battalion which used traditional BCT physical training the Control battalion, n 1275 during the 9-week BCT cycle. PRT exercises included precision calisthenics, dumbbell drills, movement drills, 30-second run30-second walk interval training, ability group runs, and flexibility training. On the first administration of the Army Physical Fitness Test APFT taken for record, the VF group had a greater proportion of trainees passing than the Control Group men 85 vs. 81, p 0.04 women 80 vs. 70, p 0.01. After all administrations of the record APFT, the VF group had fewer APFT failures than the Control group among the women 1.6 vs. 4.6, p 0.01 but not the men 1.6 vs. 2.8, p 0.18. On push-up raw scores, Control men and women improved more than the VF men p 0.01 and women p 0.01, although the VF group scores exceeded minimum BCT passing values. On sit-up raw scores there were no differences between the VF and Control men p 0.21 but the VF women improved more than the Control women p 0.01. There were no differences in improvements in 2-mile run times between the VF and Control men p 0.15 or women p 0.54. Battalion differences in injury rates were examined using Cox regression a survival analysis technique, which controlled for initial differences in demographics, fitness, and training-related variables. The relative risk of an injury of any type was 37 higher in the Control men p 0.02 and 35 higher in the Control women p 0.01, compared to the VF men and women.
