Oh, Choi, and Kim: The Effect of Lumbar Stability Exercise Program on Sedentary Life Female, Lumbosacral Region Angle, Muscular Strength, Physical Fitness and Pain Scale

Abstract

The purpose of this study is to evaluate the effect of lumbar stabilization exercise on lumbosacral region angle, lumbar strength, lower muscle strength, physical fitness, and low back pain of sedentary women. Twenty females who spend more than 6 hours a day as sedentary at working were recruited. The subjects were assigned to two different groups which are exercise group (n=10) and non-exercise group (n=10). Exercise program was consisted with Swiss ball and lumber stability exercise, and it was performed 60 min/day and 3 times/wk for 8 weeks. Two-way analysis of variance was conducted to analyze experimental data. As a result, there was no significant difference between groups in lumbar lordosis angle and lumbar sacral angle. However, Isometric lumbar extension strength, isokinetic knee flexion and extension peak torque in angular velocity were significantly different between groups, and the pain was reduced. To conclude, this study identified the effectiveness of lumbar stabilization exercise on lumbar muscular, strength, Sargent jump, sit and reach test and reduced pain.
