Brief Summary

Fibromyalgia is a painful syndrome of unknown etiology, which affects 2% of world population, with symptoms such as: pain, unrefreshing sleep, fatigue and mood disorders. It is already established in the literature that resistance training is part of the non- pharmacological treatment for patients with fibromyalgia. The big gap is about the quantity adequate and/or recommended exercise volume, despite some studies with exercise volumes different resistance trainings show improvements, we do not have a direction, besides We still do not know whether there is a preference for these patients in different resistance training volumes.

Detailed Description

Objective: Assess training volume preference resisted in women with fibromyalgia.

Method: Crossover randomized clinical trial, randomized and blind. 36 women with fibromyalgia will be evaluated, who will undergo three resistance training programs with different training volumes. The primary outcome will be patient preference in relation to training volumes, and the secondary ones will be the patient expectation, pain intensity, affect and subjective perception of exertion.

Analysis statistics: For the primary outcome preference, the number of choices will be counted of the 3 types of training in percentage form. Regarding the analysis of the primary outcome we will summarize the patient's preference in a contingency table, we will compare the proportions using the Chi-square test, and finally we will check the effect size of the observed differences. For secondary outcomes, statistical analyzes will be performed by a blind statistician using commercial software. The Kolmogorov-Smirnov test will be applied to verify the distribution of data and Levene's test will be used to analyze the homogeneity of variance. The Bonferroni test will be used in post hoc analyzes to determine whether there are differences between the groups at different intervention times. One 5% significance level and 95% CI will be adopted for all statistical analyses. ethic and dissemination: The results of the study will be disseminated to participants and subjected to a peer-reviewed journal and scientific meetings.

Primary Outcome Measures
NameTimeMethod
Choose one of the workouts according to your preference28 day

Preference will be assessed through the following question: "After carrying out the training sessions, which one did you prefer? Why?".

Secondary Outcome Measures
NameTimeMethod
Change in Affectionbaseline, 28 day

Affect scale will monitor pleasure or displeasure during the three resistance training will be carried out through the application of the affective valence scale (VA).

The scale is quantified as follows: +5 to -5, corresponding, respectively, to the two antagonistic descriptors of feelings during physical exercise and/or physical activity, which may be: "very good" and "very bad".

Change in Subjective perception of exertionbaseline, 28 day

The quantification of the intensity of each resistance training session will be determined using the session's subjective perception of exertion (RPE) method

. To this end, the following question: "How was your training session?" The answer will be provided, as recommended, 30 min after the end of the session, based on an adapted Borg scale.

Change in Expectationbaseline

The Likert Scale will be used for expectations in relation to treatment. That scale aims to assess the participant's expectations at the beginning of the study in relation to the treatment they will receive with the following questions: • "Do you think that by starting the training session with 1 set, you will: (1) get much worse, (2) get a little worse, (3) neither get better nor get worse (4) get better little and (5) improve a lot".

* "Do you think that by starting the training session with 2 sets, you will: (1) get much worse, (2) get a little worse, (3) neither get better nor get worse (4) get better little and (5) improve a lot".

* "Do you think that by starting the training session with 3 sets, you will: (1) get much worse, (2) get a little worse, (3) neither get better nor get worse (4) get better little and (5) improve a lot".

Change in Pain intensitybaseline, 28 day

Generalized pain intensity will be assessed using the Numerical Pain Scale (END), a self-report instrument validated for Portuguese. END has a sequence of numbers (from 0 to 10), where 0 represents "no pain" and 10 represents "the worst pain that you can imagine."
