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.
Women aged 18 to 65
Have a diagnosis of fibromyalgia according to the ACR 2016 criteria
Have performed resistance training in the last 6 months
Having another associated rheumatic condition
Have a trip or appointment scheduled that requires absence for the next 4 (four) weeks from the start of the survey;
Women with musculoskeletal injuries in the upper and/or lower limbs
Crossover
exercise
Other interventionexercise programs with different volumes
Choose one of the workouts according to your preference
Preference will be assessed through the following question: "After carrying out the training sessions, which one did you prefer? Why?".
Change in Expectation
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 intensity
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."
Change in Affection
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 exertion
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.
