Introduction: The fibromyalgia syndrome is a chronic disorder characterised by generalised pain, muscle stiffness, reduced physical condition and fatigue that limit their daily life activities. Little knowledge is available on the feasibility and effects of long-lasting physical training in warm water on major physical abilities related with everyday life in patients with FM. The aim of the present study was to evaluate the feasibility and effects of 8 months of supervised exercise therapy in warm water on physical function, fitness and disease impact in women with fibromyalgia. Methods: Thirty women with fibromyalgia [mean ± SD] age 50.8 ± 8.7 (years); body mass index 27.7 ± 4.1 (kg/m2); duration of symptoms 19.8 ± 7.4 (years); number of tender points 17.0 ± 1.0; number of specific drugs 1.4 ± 0.8 (antidepressives, muscular relaxants and analgesics); were randomly assigned into 2 groups: an experimental group, performing 3 weekly sessions for 60 minutes of exercise therapy in warm water (n=15); and a control group, continuing their usual care and habitual leisure-time activities (n=15). Physical function and fitness were evaluated using the following tests: 10-m maximal walking speed, 10-step stair-climbing, blind one-leg stance, hand-grip dynamometry and Canadian Aerobic Fitness. The disease impact was evaluated using the Fibromyalgia Impact Questionnaire (FIQ). The data was examined by applying statistical tests for the analyses of variances. Results: Patients in both groups were in a similar condition at baseline. After 8 months of exercise therapy, the experimental group showed improvements in several aspects of physical function and fitness, such as balance (30%; p=0.031), maximal walking speed (6%; p=0.006), stair-climbing capacity with no extra weight (14%; p=0.003) and 10 kg-weighted (25%; p = 0.002) and maximal oxygen uptake (8%; p=0.015). These patients also showed ameliorations of the disease impact in terms of pain (9%; p = 0.040), stiffness (53%; p=0.015), anxiety (41%; p=0.037), depression (28%; p=0.030) and self-perceived physical function (20%; p=0.047), with an overall reduction in the total FIQ score (18%; p=0.017). Conclusion: 8 months of aquatic exercise therapy for fibromyalgia was feasible and led to relevant improvements in physical function and fitness, reducing the disease impact in FM women.
