Abstract
The purpose of this study was to assess the effects of resistance exercise training (RET) on aortic wave reflection and hemodynamics during recovery from acute resistance exercise in women with fibromyalgia (FM) and healthy women (HW). Nine women with FM (aged 42± 5years; mean± SD) and 14 HW (aged 45± 5years) completed testing at baseline and after 12weeks of whole-body RET that consisted of 3 sets of 5 exercises. Heart rate (HR), digital blood pressure (BP, plethysmography), aortic BP, and wave reflection (radial tonometry) were assessed before and 20min after acute leg resistance exercise. Aortic and digital diastolic blood pressure (DBP) were significantly decreased (p< 0.05) and aortic and digital pulse pressures (PP) were significantly increased (p< 0.05) after acute exercise before RET. Acute resistance exercise had no effect on HR, wave reflection (augmentation index and reflection time), digital, or aortic systolic BP. RET improved muscle strength without affecting acute DBP and PP responses. Acute resistance exercise produces postexercise diastolic hypotension without affecting systolic blood pressure, HR, and wave reflection responses in women with and without FM. RET does not alter resting and postexercise hemodynamics and aortic wave reflection in premenopausal women.
