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 .
A systematic review of the effectiveness of eccentric strength training in the prevention of hamstring muscle strains in otherwise healthy individuals.
BACKGROUND Hamstring strains are the most common soft-tissue injury observed in recreational and athletic activities , yet no consensus exists regarding appropriate primary and secondary strategies to prevent these strains . Eccentric exercise has been reported to reduce the incidence of ham-string strains but its role has not been clearly defined . OBJECTIVE The objective of this systematic review was to determine the effectiveness of eccentric exercise in preventing hamstring strains . DATA SOURCES Online data bases , including MED-LINE , PubMed , CINAHL , PEDro , SPORTD iscus , EMBASE , Cochrane Data base of Systematic Review s , Cochrane Central Register of Controlled Trials , and Web of Science were search ed for relevant articles . Each data base was search ed from the earliest date to July 2007 . STUDY SELECTION Selection criteria included diagnosis of hamstring strain , otherwise healthy individuals , and at least one group receiving an eccentric exercise intervention . Seven articles { three r and omized controlled trials ( RCTs ) and four cohort studies } met the inclusion criteria . DATA EXTRACTION Data were extracted using a customized form . Method ological rigor of included studies was assessed using the PEDro scale and Oxford Centre for Evidence -based Medicine Levels of Evidence . DATA SYNTHESIS STUDIES WERE GROUPED BY ECCENTRIC EXERCISE INTERVENTION PROTOCOL : hamstring lowers , isokinetic strengthening , and other strengthening . A best- evidence synthesis of pooled data was qualitatively summarized . CONCLUSIONS Findings suggest that eccentric training is effective in primary and secondary prevention of hamstring strains . Study heterogeneity and poor method ological rigor limit the ability to provide clinical recommendations . Further RCTs are needed to support the use of eccentric training protocol s in the prevention of hamstring strains
