Introduction: Augmentation Index (AIx) is a surrogate measure of systemic arterial stiffness and wave reflections. Clinic measures of AIx are considered to be a sensitive measure of risk in young adults and are lower in individuals who take part in high levels of physical activity (PA). The development of an ambulatory blood pressure monitoring (ABPM) system, which also calculates AIx, now allows usual AIx to be assessed. The aim of this study was to assess the association between 24-hour AIx and levels of physical activity in a young healthy cohort. Methods: Forty-six adults (23±5years, 28% male) took part in the study. 24-hour AIx@75 (AIx at heart rate 75bpm) was measured using the ABPM device (Mobil-O-Graph, IEM). Weekly PA levels were recorded using a detailed PA questionnaire (total minutes per week). Results: An inverse association between 24-hour AIx@75, Night-time AIx@75 and levels of PA (r =−0.420, P |
