Effect of Short Term Static·Dynamic Lumbar Stability Exercise on the Trunk Muscles Strength and Endurance of Chronic Low Back Pain Female College Students in Their 20 s. KINESIOLOGY, 2016, 18(2): 63-69. [PURPOSE] The purpose of this study was to evaluate effects of short term static · dynamic lumbar stability exercise on the trunk muscles strength and endurance of chronic low back pain female college students in their 20 s. [METHODS] The sub-jects were consisted of twenty patients who had non specific chronic low back pain. All subjects randomly assigned to the stat-ic lumbar stabilizing exercise group(n=10)and dynamic lumbar stabilizing exercise group. Dynamic lumbar stabilizing exercise group received 3D balance, static lumbar stabilizing exercise group received bridge exercise during 4 weeks period. HUR was used to measure the isometric muscle strength. Time watch measure method was used to measure the abdominal and back muscle strength and endurance of trunk flexion and extension. [RESULTS] The trunk muscle strength was significantly differ-ence between group(p<.05), Short term dynamic lumbar stabilizing exercise group was significantly increased than short term static lumbar stabilizing exercise group(p<.05). Endurance of trunk flexion, extension weren t significantly difference between group(p>.05). [CONCLUSIONS] Short term dynamic lumbar stabilizing exercise group showed increase in trunk muscle strength. Both group were increased endurance of trunk flexion, extension. Therefore, Short term dynamic and static lumbar stabilizing exercise will be available in the intervention of chronic low back pain patients.
