About this study

Thirty participants will be recruited. Volunteers will be randomly assigned to the control group or experimental group. Before the training period, symptoms, balance and neuromuscular performance will be assessed. Participants in the experimental group will perform strength training twice a week (50 min each) for eight weeks. Then, four weeks of detraining will be completed.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Treatment and study plan

Strength exercise

Other

The protocol consists of 8 weeks of training, consisting of 16 sessions of 50 minutes, twice a week on alternate days.

Primary outcomes

  1. Balance

    Time frame: Change from Baseline balance at week 9

    Force plate

  2. Balance

    Time frame: Change from Baseline balance at week 12

    Force plate

  3. Balance

    Time frame: Change from week 9 balance at week 12

    Force plate

  4. Neuromuscular performance

    Time frame: Change from Baseline neuromuscular performance at week 9

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

  5. Neuromuscular performance

    Time frame: Change from Baseline neuromuscular performance at week 12

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

  6. Neuromuscular performance

    Time frame: Change from week 9 neuromuscular performance at week 12

    Optical measurement system consisting of two transmitting and receiving cells to assess vertical jump and medicine ball to assess strength of the upper limbs.

Secondary outcomes

  1. Fibromyalgia impact questionnaire

    Time frame: Baseline, week 9, week 12

    Questionnaire to ccess information on the functional capacity and health status of individuals with fibromyalgia. Composed of 20 questions. , the values vary from 0 to 100, in which the higher the value, the greater the impact of fibromyalgia.

  2. Pain intensity

    Time frame: baseline and everyday until the week 12

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

  3. Anxiety

    Time frame: baseline and everyday until the week 12

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

  4. Quality of sleep

    Time frame: baseline and everyday until the week 12

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

  5. Fatigue

    Time frame: baseline and everyday until the week 12

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.

  6. Mood state

    Time frame: baseline and everyday until the week 12

    Visual Analogue Scale (VAS). The scoring range will be from 0 to 100, in which the higher the value, the greater the intensity. During non-presencial days, participants will respond daily the intensity with a cell phone application developed for this purpose.
