The association between exercise enjoyment and physical activity in women with fibromyalgia.

Evidence suggests the role of physical activity (PA) in management of clinical symptoms of fibromyalgia. However, very little is known regarding the psychological correlates of PA in patients with fibromyalgia. Therefore, this study examined the association between exercise enjoyment (EE) and PA in women with fibromyalgia. 19 women with fibromyalgia completed a laboratory session, where EE was assessed using a self-report questionnaire immediately after 20 min of light-intensity biking. Muscle pain ratings (MPR) in the legs were assessed during exercise, and changes in clinical pain intensity after exercise were computed. PA was assessed subjectively using a self-report questionnaire and objectively using an accelerometer for one week. Results from correlation analyses indicated that EE was associated with the self-reported amount of PA (rs=0.61, R(2)=0.37, p<0.01) and the minutes spent for moderate intensity PA (rs=0.48, R(2)=0.23, p<0.05). However, neither MPR nor changes in clinical pain intensity were associated with PA. These results suggest that EE may serve as a determinant of PA in women with fibromyalgia. Future research is needed to develop interventions to maximize EE to promote PA in this clinical population.
