Currently, several myofascial release techniques work to improve muscle flexibility. <strong>Objective:</strong> To analyze the relationship between flexibility and muscle strength of the knee flexors and to verify the acute effect of two modalities of myofascial release on the flexibility of the hamstrings. <strong>Methods:</strong> 45 women participated in this study, divided into Manual Release Group, Instrumental Release Group, and Control Group. A sit and reach test, a third finger floor test, an assessment of the popliteal angle, and an assessment of knee flexion muscle strength were performed. Subsequently, the volunteers received a myofascial release session in the hamstring muscle group. After treatment, the volunteers were reassessed. <strong>Results:</strong> Both groups that received myofascial release performed better in flexibility tests. There was no correlation between hamstring flexibility and the ability to produce joint torque from knee flexion. <strong>Conclusion:</strong> The flexibility of the hamstring muscles did not influence the ability to produce knee flexion torque and both myofascial release techniques were effective in improving the flexibility of this musculature.</p>}, journal={Manual Therapy, Posturology & Rehabilitation Journal}, author={Spinoso, Deborah Hebling and Goulart, Murilo and Ferreira, Antonio and Navega, Marcelo}, year={2022}, month={Sep.}, pages={1–7} }
