Effects of a strength training program on daily living in women with fibromyalgia

Abstract

Background. The fibromyalgia among other symptoms is associated with poor physical condition in relation to the loss of muscle mass, which produces an increase in muscle disability. This directly affects the state of health because it causes limitations to perform the tasks of daily living. Objective. The aim was to analyse the effect of the progressive strength program on dimensions that affects to quality of life and to value the changes produced during the program. Design. Controlled quasi-experimental analytical study evaluating the response to the intervention program at three specific moments. Methods. 41 women with fibromyalgia participated in this study fulfilling the inclusion criteria. The participants completed a total of 24 weeks of training program based on strength work oriented to daily life activities. The program consisted of a total of 3 progressive and controlled phases in volume and intensity to improve muscle strength that affects the performance of daily living activities. Results. We obtained statistical differences (P < 0.001) and high clinical effects (d > 0.60) in all strength test and all domains of the Revised Fibromyalgia Impact Questionnaire at the end of the intervention. Conclusions. The improvements produced in functional capacity allows them to perform tasks that were previously incapable. The muscle strengthening program based on strength work twice a week on non-consecutive days with a total duration of 1 hour, improves the quality of life related to health, symptomatology, physical function and the severity of disease.
