Avaliação do efeito agudo do rolo de liberação miofascial na mobilidade, dor e fadiga após esforço intenso

Abstract

Introduction: Self-myofascial release has been widely performed, however, a few studies have verified its effects on the flexibility, fatigue perception and pain mechanical threshold of quadriceps in individuals in a fatigated state. The purpose of this research was to assess the foam roller effects on the flexibility, mechanical pain threshold and perceived fatigue of the quadriceps in young adults submitted to a fatigue protocol. Methods: A experimental, randomized, parallel study, was conducted. We selected healthy young subjects, men, and women, which practice any sports modality. The subjects were divided into two groups: Foam Roller and Minimal Intervention. The participants of both groups performed a quadriceps fatigue protocol on the isokinetic dynamometer. Flexibility, mechanical pain threshold and perceived fatigued were assessed as dependent variables. Group FR performed self-myofascial release with a foam roller while the MI group performed 30 seconds of soft hand stimulus. Results: 10 subjects with a media of 22.8± 1.3 and 25.6±2.4 years, in the FR and MI group respectively, take part in the study. Groups were similar (p>0.05) in regard to demographics (age, weight, height) and dependent variables in the baseline. No difference was found in the quadriceps flexibility between pre and post-intervention period. Both groups had an important reduction (p>0.05) on the perceived fatigue after intervention but not superiority was detected between them. The Mechanical Pain Threshold didn't change over time in any group. Conclusion: Effects of self-myofascial release over flexibility, mechanical pain threshold, and perceived fatigue are similar to a minimal intervention.
