Central and peripheral blood pressures will be assessed in the following four conditions during each of the three assessment sessions: i) fasted, supine, ii) fasted, seated, iii) non-fasted supine, and iv) non-fasted seated. During each of the above conditions two measurements will be taken, separated by a three-minute interval. If blood pressure differ by > 5mmHG a third recording will be taken and the closest recordings will be averaged. Each of the above conditions will be undertaken following a minimum 15 minutes quite rest.
