Illustrative recovery half-times of relative blood flow (rBF), change in oxyhemoglobin concentration (Δ[HbO 2 ]) and change in deoxyhemoglobin concentration (Δ[Hb]) following fatiguing exercise in (a) a subject with fibromyalgia (FM) and (b) a healthy control. The vertical solid lines indicate the ending of exercise. The horizontal dashed and dotted lines indicate the maximal and half-maximal recovery values of hemodynamic variables, respectively. The vertical dotted lines indicate the recovery half-times.
