Effect of Resistance Training on Lumbar Extension Torque Production

    This study is from a physical therapy research paper which examines the impact of isometric lumbar extension torque across 12- and 20-week periods. Participants were put into 5 training groups after completing the 12- or 20-week training. The participants were tested in a seated position at 7 different angles at a 72-degree range of motion (ROM).
