Abstract: Background: Fibromyalgia (FM) is a complex syndrome with skeletal muscle impairment. However, respiratory muscles responses are unknown. Purpose: we aimed to study strength resistance in both respiratory and skeletal muscles in FM and healthy controls. Methods: fifteen women with FM - FG group - (50 ± 11 years) and 10 healthy controls - CG - (48 ± 11 years) underwent clinical evaluation, skeletal muscle strength and resistance tests, respiratory tests, six-minute walk test and step test. Results: both groups were similar in demographic and anthropometric variables. Respiratory muscle strength was significantly lower in FG (46 ± 6 cm HO) compared to CG (80 ± 8 cm HO; p < 0.05). Similarly, 22 skeletal muscle (71 ± 8 vs 167 ± 24 repetitions, p < 0.05) and respiratory muscle strength (29 ± 4 vs 56 ± 6 repetitions, p < 0.05) were lower in FG compared to CG. Moreover, CG showed greater distance on 6 - minute walk test (551 ± 36 vs 460 ± 86 m; p < 0.05) and higher number of steps (102 ± 9 vs 76 ± 13 steps; p < 0.05). Only FG showed significantly correlation between skeletal muscle and respiratory muscle strength (r = 0.64; p < 0.001). Conclusion: FM syndrome showed an impairment in both respiratory muscle strength and resistance, which could impair exercise tolerance in these patients.
