The effect of Tai Chi and Zumba Gold on vascular function in an ageing population

Abstract

Aging is associated with an increased incidence of disease, such as cardiovascular disease. This occurs via several mechanisms including oxidative stress and chronic inflammation, which can cause a reduction in vascular compliance via impairment in endothelium dependant dilation and arterial stiffness. Many of these adverse effects can be reduced or overcome by exercise however, not all exercise is perceived as suitable for an older age population. This study will investigate 2 types of exercise undertaken at different intensity: a low/moderate intensity (Tai Chi) versus moderate/high intensity (Zumba Gold). The study will assess the effect of 12 weeks of Tai Chi or aerobic dance, on markers of oxidative stress, inflammation and vascular function. Participants aged between 65 and 75 years old, with no history of cardiovascular diseases will be recruited to the study. Following screening and baseline measures they will be randomised into 3 groups of control (social-interaction), Tai Chi and aerobic dance (Zumba Gold). All participants will take part in 12 weeks of intervention and will be assessed for vascular function (FMD), biochemical parameters of inflammation and oxidative, physical fitness, psychological effects (depression, pain, fatigue, loneliness) and other health parameters (BMI, lipid profile, blood pressure). Measurements will be taken at baseline, 6 weeks (mid-intervention) and 12 weeks (end-intervention). This study aims to provide a better understanding of the effects of two different forms of exercise on markers of health in older age, and to assess these two different types of exercise for acceptability in this population.
