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 .
Effects of pool-based exercise in fibromyalgia symptomatology and sleep quality: a prospective randomised comparison between stretching and Ai Chi.
OBJECTIVE To evaluate the effectiveness and tolerability of two pool-based physical therapies , stretching and Ai Chi , in fibromyalgia symptomatology and sleep quality . METHODS Eighty-one patients , r and omly assigned to stretching ( n=39 ) or Ai Chi ( n=42 ) , received 18 physiotherapy sessions  and were evaluated at baseline , at treatment termination , and after 4 and 12 weeks of follow-up . Main outcome measures were the Fibromyalgia Impact Question naire ( FIQ ) and the Pittsburgh Sleep Quality Index ( PSQI ) . Secondary outcome measures included the Beck Depression Inventory ( BDI ) , the State and Trait Anxiety Inventory ( STAI ) , and the SF-12 Health Survey ( SF-12 ) . Data analysis was done with repeated measures ANOVA and effect size estimation . RESULTS No differences were found between groups but significant reduction in the FIQ and the PSQI scores were observed in Ai Chi but not in stretching group , with larger effect sizes and longer effect duration on sleep measures . BDI scores decreased in stretching but not in Ai Chi group with small effect sizes . Trait-anxiety scores decreased in both groups also with small effect sizes . The mental component summary of the SF-12 increased only in stretching group with effect sizes moderate to large . CONCLUSIONS Although no global differences were found between groups , Ai Chi significantly improved fibromyalgia symptomatology and sleep quality , whereas stretching only improved subjects ' psychological well-being
