Conclusion The main results included reduction in pain , fatigue , number of tender points , depression , and anxiety , with increased functional capacity and quality of life .
Background Fibromyalgia ( FM ) is characterized by chronic and generalized musculoskeletal pain .
There is currently no cure for FM , but palliative treatments are available .
One type of treatment is strength training ( ST ) .
However , there is a need for more information on optimal training protocol s , intensity , and volume needed to improve symptoms .
The aim of this study was to analyze the effects of ST in the treatment of FM through a systematic review of experimental research .
Effects of strength vs aerobic exercise on pain severity in adults with fibromyalgia: A randomized equivalence trial
Summary Strengthening and aerobic exercise had equivalent effects on reducing pain severity in patients with fibromyalgia .  Abstract Strength training and aerobic exercise have beneficial effects on pain in adults with fibromyalgia . However , the equivalence of strengthening and aerobic exercise has not been reported . The primary aim of this r and omized equivalence trial involving patients with fibromyalgia admitted to an interdisciplinary pain treatment program was to test the hypothesis that strengthening ( n = 36 ) and aerobic ( n = 36 ) exercise have equivalent effects ( 95 % confidence interval within an equivalence margin ±8 ) on pain , as measured by the pain severity subscale of the Multidimensional Pain Inventory . Secondary aims included determining the effects of strengthening and aerobic exercise  on peak Vo2 uptake , leg strength , and pressure pain thresholds . In an intent‐to‐treat analysis , the mean ( ± st and ard deviation ) pain severity scores for the strength and aerobic groups at study completion were 34.4 ± 11.5 and 37.6 ± 11.9 , respectively . The group difference was −3.2 ( 95 % confidence interval , −8.7 to 2.3 ) , which was within the equivalence margin of Δ8 . Significant improvements in pain severity ( P < .001 ) , peak Vo2 ( P < .001 ) , strength ( P < .001 ) , and pain thresholds ( P < .001 ) were observed from baseline to week 3 in the intent‐to‐treat analysis ; however , patients in the aerobic group ( mean change 2.0 ± 2.6 mL/kg/min ) experienced greater gains ( P < .013 ) in peak Vo2 compared to the strength group ( mean change 0.4 ± 2.6 mL/kg/min ) . Knowledge of the equivalence and physiological effects of exercise have important clinical implication s that could allow practitioners to target exercise recommendations on the basis of comorbid medical conditions or patient preference for a particular type of exercise . This study found that strength and aerobic exercise had equivalent effects on reducing pain severity among patients with fibromyalgia
