Description

Purpose The purpose of this study was to identify the influence of our designed group training on pulse wave velocity in elderly women.<br/>Method Eighty six elderly women were assigned to two groups randomly; an intervention group (69.8±7.2yrs) and a control group (68.9±7.3yrs). In the intervention group, subjects participated in 90-min group training twice a week for 12 weeks. Our designed training program included recreational activities, six to eight resistance exercises for circuit training using rubber tubes and light weight dumbbells, and chair-based aerobic exercise. Systolic (SBP) and diastolic blood pressure (DBP) and the brachial-to-ankle pulse-wave velocity (baPWV) were obtained in the supine position. Functional fitness with regard to standing, walking, hand work, and self-care was also measured.<br/>Results Changes in ratios of SBP, DBP and baPWV between before and after the intervention were −3.3±8.4%, −4.3±7.8%, and −8.9±5.0% for the intervention group, and 1.7±7.9%, 0.9±7.7%, and 0.2±5.4% for the control group. The differences between the two groups were significant (P<0.01). Change in ratios for standing and self-care also significantly differed (P<0.05).<br/>Conclusion These results suggested that our designed group training for elderly women improves arterial function and functional fitness.
