Abstract Specific aim: The specific aim of this project is to assess the effectiveness of a high intensity progressive resistance exercise training program targeting the l umbar extensors to improve lumbar extensor muscular strength and endurance (the desired physiological responses) in US Army Soldiers. Hypothesis: A high intensity progressive resistance exercise for the lumbar extensors will result in a 25% increase in lumbar extensor muscular strength and endurance compared with control following the 12-week intervention. Design: A mixed methods, two-arm, controlled clinical trial with cluster randomization will be conducted. The sampling frame will be soldiers training to become combat medics from 12 platoons, within 3 companies of one domestic US Army base (Fort Sam Houston, TX). Soldiers (n = 592 from 12 platoons) will be randomly assigned (by platoon) to one of two interventions - experimental (n = 296 soldiers from 6 platoons) or control (n = 296 soldiers from 6 platoons). All participants at a given platoon will receive the same intervention and all interventions will be carried out at the US Army base, in addition to the soldiers usual physical fitness training program. Participants randomized to the experimental group will perform lumbar extensor muscle progressive resistance exercise using standardized protocols. Exercise training will consist of 1 set of high intensity, progressive resistance exercise for lumbar extensors on specialized equipment. Participants in the control group will perform 5 minutes of low intensity core stabilization exercises on the floor. Interventions will be carried out 1X/week for 12 weeks. Outcome measures that will be utilized to test the hypothesis include validated physical fitness tests for lumbar extension muscular strength and endurance. Fitness tests will be conducted at baseline and following the 12-week intervention period.
