Clinical Trial Summary

Aging is associated with progressive decreases in arterial health and function as well as overall fitness. It is crucial to prevent or reduce the negative effects of aging on the vasculature and fitness components by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a swimming (SWM) regimen on arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), wave reflection (AIx), muscle strength and aerobic capacity in elderly women with stage 2 hypertension.

Description:

Using a parallel experimental design, participants were randomly assigned to either SWM (n=52) or non-exercising control group (n=48) for 20 weeks. Participant in the SWM group trained 3-4 days/week, progressing in duration from 25 to 45 min. Participants' carotid to radial PWV (crPWV), systolic and diastolic BP, AIx, strength and VO2max were measured at baseline and after 20 weeks of their assigned intervention.
