Efeito de duas técnicas de alongamento no ganho de flexibilidade de cadeia posterior em mulheres sedentárias

Effect of two stretching techniques on the flexibility gain of back chain in sedentary women

Abstract

Introduction: The loss of flexibility of the posterior chain results in several biomechanical dysfunctions, the use of stretching presents itself as a resource to restore this deficit. Objective: To verify the effect and compare the effectiveness of static stretching and muscle energy technique for gain of posterior chain flexibility. Methods: Intervention study with a control group, which evaluated 27 sedentary women, who presented posterior chain shortening, divided into 3 groups: static stretching, muscular energy technique, and the control group. At the end of the intervention period women were revaluated through the Banco de Wells. The comparison of means, before and after the performance of the techniques was evaluated through Student's T-Test. The Wilcoxon test was used to verify the classification of women according to the Banco de Wells. Results: There was a significant increase in the means after static stretching (35% increase, p = 0.001) and muscle energy technique (72% increase, p = 0.001), while the control group remained unchanged. It was also verified that after the intervention, the women had better ratings according to the Banco de Wells. Conclusion: Both techniques were positive in obtaining hamstring flexibility. However, the muscle energy technique was more effective when compared to static stretching.
