The Effect of Detraining on Beta-endorphin, Pain, and Functional disability of Men with Low Back Pain Following Two Types of Core Stability and suspension Exercises

Today, back pain is one of the most common and costly medical problems and the main cause of absence from work. The aim of this study was to investigate the effect of detraining on beta-endorphin, pain and functional disability in men with low back pain following two types of suspension and core stability exercises.In the present semi-experimental study, which was performed by repeated measurements, ۳۲ men with chronic low back pain were selected by recall and randomly divided into three groups of core stability exercises, suspension and control. Serum beta-endorphin was measured by the Eliza method, pain was measured by VAS visual analog scale, and functional disability was measured by oscilloscope questionnaire one day before and immediately after ۸ weeks of training and ۸ weeks of detraining.The results of the present study indicated that there was a significant improvement in reducing pain and functional disability (P<۰.۰۵) after the intervention in both groups, while there was no significant change in the control group. Intergroup comparison showed that the suspension group had a significant improvement in pain and functional disability (P<۰.۰۵) compared to the core stability group, but the difference in serum beta-endorphin was not significant (P˃۰.۰۵). Also, changes in both training groups compared to the control group were significant in all variables (P<۰.۰۵). However, no significant difference was observed between the intervention and control groups on pain and functional disability (P˃۰.۰۵).The results showed that both types of exercises improved beta-endorphin, pain, and functional disability in men with low back pain, however, the role of suspension exercises in reducing pain and functional disability was more pronounced than core stability exercises. It was also found that lack of training returned the results of the training to the time before it, specially in suspension group.
