There were no statistically significant differences in attrition rates between the interventions .
In general , adverse effects were poorly recorded , but no serious adverse effects were reported .
The evidence ( rated as low quality ) suggested that moderate- and moderate- to high-intensity resistance training improves multidimensional function , pain , tenderness , and muscle strength in women with fibromyalgia .
The evidence ( rated as low quality ) also suggested that eight weeks of aerobic exercise was superior to moderate-intensity resistance training for improving pain in women with fibromyalgia .
There was low- quality evidence that 12 weeks of low-intensity resistance training was superior to flexibility exercise training in women with fibromyalgia for improvements in pain and multidimensional function .
There was low- quality evidence that women with fibromyalgia can safely perform moderate- to high-resistance training
BACKGROUND Fibromyalgia is characterized by chronic widespread pain that leads to reduced physical function .
Exercise training is commonly recommended as a treatment for management of symptoms .
We examined the literature on resistance training for individuals with fibromyalgia .
Resistance training is exercise performed against a progressive resistance with the intention of improving muscle strength , muscle endurance , muscle power , or a combination of these .
OBJECTIVES To evaluate the benefits and harms of resistance exercise training in adults with fibromyalgia .
We compared resistance training versus control and versus other types of exercise training .
Effectiveness of physical activity in reducing pain in patients with fibromyalgia: a blinded randomized clinical trial
The purpose of this study was to evaluate and compare the effectiveness of muscle-strengthening exercises ( MS ) and a walking program ( WA ) in reducing pain in patients with fibromyalgia . Ninety women , 30–55 years of age , diagnosed with fibromyalgia according to the American College of Rheumatology 1990 criteria , were r and omized into 3 groups : WA Group , MS Group , and control group . Pain ( visual analog scale ) was evaluated as the primary outcome . Physical functioning ( Fibromyalgia Impact Question naire , FIQ ) , health-related quality of life ( Short-Form 36 Health Survey , SF-36 ) , and use of medication were evaluated as secondary outcomes . Assessment s were performed at baseline , 8 , 16 , and 28 weeks . Intention-to-treat and efficacy analyses were conducted . Sixty-eight patients completed the treatment protocol . All 3 groups showed improvement after the 16-week treatment compared to baseline . At the 28-week follow-up , pain reduction was similar for the WA and MS groups ( P = 0.39 ) , but different from the control group ( P = 0.01 ) . At the end of the treatment , 80 % of subjects in the control group took pain medication , but only 46.7 % in the WA and 41.4 % in the MS  groups . Mean FIQ total scores were lower for the WA and MS groups ( P = 0.96 ) compared with the control group ( P < 0.01 ) . Patients in the WA and MS groups reported higher scores ( better health status ) than controls in almost all SF-36 subscales . MS was as effective as WA in reducing pain regarding all study variables ; however , symptoms management during the follow-up period was more efficient in the WA group
