Methods: this is a randomized clinical trial. A total of 14 female soccer players participated in the study. A sociodemographic and clinical questionnaire was applied to the participating athletes, after was performed evaluations in the isokinetic dynamometer of knee extensors and flexors. Participants were randomly divided into two groups, with one intervention group (IG) and one control group (CG). Participants in the IG performed routine warming of the SMR associated club with a foam roller. The participants in the CG did the same warming, but without SMR association. After 48 hours of isokinetic evaluation, the SMR protocol was started, which lasted two weeks and was applied to the quadriceps, hamstring and calf muscle groups. After 48 hours of the last intervention, a reevaluation was performed in the isokinetic dynamometer. Results: there were no significant effects between groups in the post-test. In the pre- and post-test comparison between groups, there was a significant decline in the peak torque variable of extension of the dominant lower limb in the non-SMR group (p = 0.013). Conclusion: it was concluded that a chronic SMR approach was not able to generate significant changes in muscle strength, but it seems to reduce the harmful effects generated by high training volumes.Acesso AbertoAuto liberação miofascialFásciaForça muscularFutebolSelf-myofascial releaseFasciaStrength muscleSoccerTrabalho de Conclusão de CursoCiências da SaúdeFisioterapia
