Title: The effect of mobility on the cardiometabolic profile of older adults

PhD summary

Sedentary behaviour physiology has become a growing topic area over the last decade due to realisation that sedentary behaviour (seated or reclined postures expending <1.5 METs) affects the human body independently of moderate intensity physical activity. This means that performing physical activity may not negate the negative side effects of prolonged sedentary behaviour.

My research at the Health, Exercise, and Active Living (HEAL) Research Centre involves monitoring older adult’s mobility levels using accelerometry throughout a ‘normal’ week. These mobility levels are then compared with cardiometabolic health parameters (e.g. intima-media thickness, flow mediated dilation, lipoprotein lipase concentration) to determine whether sedentary behaviour or physical activity, of varying intensities, influences health status.
