The beneficial effects of a strength exercise program and a combined exercise program of strength training plus walking were examined in overweight with chronic back pain patients. The participants were ran-domly placed in the strength exercise group (SEG, n=15), combined ex-ercise group (CEG, n=15), and control group (CG, n=6). All subjects performed exercise twice per week, 50 min per session with a profes-sional instructors for 12 weeks. In order to evaluate exercise interven-tion effects, lumbar function was measured by back strength and flexi-bility. Roland-Morris disability questionnaire (RMDQ) and visual ana-logue scale (VAS) were used to evaluate pain level. Fat and muscle mass were measured to compare body composition changes. All mea-surements were performed before and after 12 weeks of exercise pro-gram. Lumbar function: Back strength was significantly different over time, and significant time×group differences were found between SEG and CG and, CEG and CG. Pain disorder degree: VAS showed a signifi-cant group difference, and significant time×group differences were shown between SEG and CG, and CEG and CG. Also, RMDG showed a significant difference between CEG and CG. Body composition: Fat mass was significantly different over time×group between SEG and CG. In conclusion, participating in strength and walking exercises were beneficial to improve lumbar function. Also, the combined exercise pro-gram was more effective for reducing pain levels than the strength ex-ercise. Finally, fat mass was reduced in this study and this may play a possible role in the improvement of lumbar function and reduction in low back pain.
