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 .
Six-month and one-year followup of 23 weeks of aerobic exercise for individuals with fibromyalgia.
OBJECTIVE To measure mood and physical function of individuals with fibromyalgia , 6 and 12 months following 23 weeks of supervised aerobic exercise . METHODS This is a followup report of individuals who were previously enrolled in 23 weeks of l and -based and water-based aerobic exercise classes .  Outcomes included the 6-minute walk test , Beck Depression Inventory ( BDI ) , State-Trait Anxiety Inventory , Arthritis Self-Efficacy Scale ( ASES ) , Fibromyalgia Impact Question naire ( FIQ ) , tender point count , patient global assessment score , and exercise compliance . Outcomes were measured at the start and end of the exercise classes and 6 and 12 months later . RESULTS Analyses were conducted on 29 ( intent-to-treat ) or 18 ( efficacy ) subjects .  Six-minute walk distances and BDI total scores were improved at followup ( all analyses ) . BDI cognitive/affective scores were improved at the end of 23 weeks of exercise ( both analyses ) and at the 12-month followup ( efficacy analysis only ) . BDI somatic scores were improved at 6-month ( both analyses ) and 12-month followup ( intent-to-treat only ) . FIQ and ASES function were improved at all followup points . ASES pain was improved in efficacy analyses only ( all followup points ) . Tender points were unchanged after 23 weeks of exercise and at followup . Exercise duration at followup ( total minutes of aerobic plus anaerobic exercise in the preceding week ) was related to gains in physical function ( 6- and 12-month followup ) and mood ( 6-month followup ) . CONCLUSION Exercise can improve physical function , mood , symptom severity , and aspects of self efficacy for at least 12 months . Exercising at followup was related to improvements in physical function and perhaps mood
