Abstract

Metabolic syndrome (MetS) is associated with an increase in cardiovascular (CV) mortality, partially due to arterial stiffening, which can be measured non-invasively via pulse wave velocity (PWV). Arterial stiffness is a clinically relevant CV marker of mortality, an increase in PWV by only 1 SD is associated with an increased CV risk of 15%. Land based aerobic exercise, both chronic and acute, has previously been identified as an effective method for improving arterial health. Unfortunately, land based aerobic exercise is not feasible for all populations, therefore a more effective treatment modality must be elucidated. Aquatic exercise has previously been shown to be beneficial for reducing blood pressure, as well as PWV. Fruit and vegetable (F&V) consumption has been shown to decrease CV mortality, although the mechanism of action has yet to be fully elucidated. We tested the following hypotheses: 1) 8 week of dietary intervention, with increased fruit and vegetable consumption, as well as decreased complex carbohydrate and decreased fat consumption, will improve arterial hemodynamics 2) 8 weeks of aquatic exercise intervention will improve the PWV in women with MetS.
