ABSTRACTObjective: To know which type of exercise program -i.e. Pilates, hypopressive abdominal exercise or traditional exercises– develops greater muscle strength and flexibility of the lower back and lower extremity muscles in patients with mechanical low back pain. Material and methods: This was a quasi-experimental, longitudinal, non-blinded and prospective study on a simple of 30 patients selected by a quota. The patients were from 20 to 45 years old and they were divided into three groups: a) traditional gymnastics or exercises; b) Pilates; and c) hypopressive program. The flexibility of lower members and spine, and the abdominal and paravertebral strength muscles were assessed before and after the exercise program. The activation time and the amplitude of abdominal muscles were analyzed by means of an electrophysiological study. A paired Student t test, Wilcoxon and U Mann-Whitney were used for the statistical analysis of the data. Results: There was a statistically significant improvement in flexibility in all the groups. Pilates and hypopressive abdominal exercises showed a greater improvement in flexibility when compared to traditional exercises and the muscle strength showed no significant improvement in any of the groups after the exercise program. The superficial electromyographical analysis showed a significant improvement in activation and amplitude in all the three groups, showing a greater improvement in the Pilates and hypopressive abdominal exercise group. Conclusion: The three programs demonstrated an improvement in the flexibility of the lower back and lower extremities muscles strength. Conclusion: All three groups improved. The best results were observed in the Pilates and the hypopressive abdominal exercise groups. . Strength did not change significantly in any of the groups.
