Objective: To compare the heart rate variability (HRV) before and after a sub-maximal exercise test in women with fibromyalgia (FM) and to compare the result to matched controls. Additionally, to compare heart rate (HR) before, during and after the sub-maximal exercise test. Methods: Twenty-four women with FM and 26 controls performed a sub-maximal exercise test. HRV was registered for 5 minutes at rest before and after the exercise test. HR was registered at baseline, during the exercise test and at recovery. Results: The HRV of the healthy group was statistically different from the exercise test but the women with FM showed no such difference. HR was significantly higher among the women with FM than in the healthy group at baseline and up to 75W but lower at peak (138/152 bpm, p<0.008). In women with FM HR during exercise (HR2) was predicted by heart rate recovery (HRR20) and phy.. View More»
