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 .
Cardiovascular autonomic modulation after acute resistance exercise in women with fibromyalgia.
OBJECTIVE To test the hypothesis that autonomic modulation after resistance exercise ( RE ) would be reduced in women with fibromyalgia ( FM ) compared with controls . DESIGN Before-after trial . SETTING Testing occurred in a university setting . PARTICIPANTS Women with FM ( n=9 ) and healthy controls ( n=9 ) underwent testing before ( pre ) and 20 minutes after ( post ) RE . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES Normalized low-frequency ( LFnu ) and normalized high-frequency ( HFnu ) oscillations and the LFnu/HFnu ratio were indicative of sympathetic modulation , parasympathetic modulation , and sympathovagal balance , respectively . Baroreceptor reflex sensitivity ( BRS ) was also measured . RESULTS Variables were similar in both groups at rest . HFnu decreased in controls ( pre , 55.0+/-4.2 % ; post , 35.0+/-4.7 % ; P<.05 ) and increased in women with FM ( pre , 57.0+/-5.7 % ; post , 63.2+/-4.6 % ; P<.05 ) . LFnu increased in controls ( pre , 43.3+/-4.4 % ; post , 63.2+/-4.8 % ; P<.05 ) and decreased in women with FM ( pre , 41.8+/-5.6 % ; post , 35.6+/-4.7 % ; P<.05 ) . The LFnu/HFnu ratio increased in controls ( pre , 0.89+/-0.17 ; post , 2.43+/-0.64 ; P<.05 ) with no change in women with FM ( pre , 0.90+/-0.22 ; post , 0.64+/-0.13 ; P=.13 ) . BRS decreased in controls ( pre , 8.78+/-1.42 ms/mmHg ; post , 5.49+/-0.66 ms/mmHg ; P<.05 ) , but not in women with FM ( pre , 5.91+/-1.22 ms/mmHg ; post , 9.23+/-2.4 ms/mmHg ; P=.16 ) . CONCLUSIONS After acute RE , women with FM responded differently from controls , demonstrated by lower sympathetic and higher vagal modulation without altering BRS . These postexercise responses may be attributed to the altered autonomic responsiveness to physiologic stress that characterizes FM
