Avaliação da preferência de mulheres com fibromialgia submetidas a três diferentes volumes de treinamento resistido: ensaio clínico randomizado crossover

Abstract

INTRODUCTION: Resistance training is part of the non-pharmacological treatment for people with fibromyalgia. However, the appropriate and/or recommended amount of exercise, despite some studies showing improvements with different resistance training volumes, is not precisely defined. Furthermore, we do not yet know if there is a preference among these individuals regarding different volumes of resistance exercise.OBJECTIVE: To assess volume preference in three different resistance training protocols in women with fibromyalgia. Secondarily, to evaluate patient expectations, pain intensity, affect, subjective perception of effort, training volume, and cadence.METHODS: A randomized, blinded, crossover clinical trial was conducted. Thirty-eight women with fibromyalgia were included. All participants underwent three resistance exercise programs with different training volumes (one set, two sets, and three sets per exercise) over a period of three weeks. The participants were assessed before the intervention (T0), before each training session (T1, T2, and T3), after each training session (T1, T2, and T3), 24 hours after each session (T1, T2, and T3), and one week after the last session (T4). RESULTS: Participants showed a preference for the two-set and three-set training protocols. No differences were found in expectations, pain intensity, affect, subjective perception of effort, training volume, or cadence between the three different training protocols. CONCLUSION: Women with fibromyalgia preferred the two-set and three-set protocols, with 50% choosing each protocol, while none preferred the one-set protocol. No differences were found in any of the secondary outcomes assessed across the three training protocols, reinforcing that the choice of two or three sets may be considered even for fibromyalgia patients who are untrained in resistance exercises.
