The purpose of this study was to examine a factor of isokinetic leg muscular strength in amateur athletes in boxing with chronic low back pain. Subjects of this study were current amateur athletes in boxing with chronic low back pain(n=9) and the athletes without pain(n=12). Isokinetic lower limb muscular strength was measured by Isomed2000(D&R Ferstl GMBH, Germany), and the femoral muscle strengths(i.e., extensor and flexor) were measured at 60°/sec, 180°/sec and 240°/sec with three different angular velocities(i.e., low, medium and high). As a results, in the isokinetic test, hamstring to quadriceps strength ratios(ipsilateral balance index) of knee joint for the athletes in boxing increased with increased angular velocity. In the concentric contraction, subjects with chronic low back pain showed a significant difference in the left ipsilateral balance ratio at different angular velocities (p<.05), and a significant difference in peak torque ratio on left ipsilateral extensor (240°/sec, p<.05). The left ipsilateral extensor was observed as a significant factor in peak torque ratio for amateur athletes in boxing with chronic low back pain in concentric contraction, and its ratio was observed lower value by 10 percent or more on average.
