The impact of measurement timepoint on autonomic function testing in male and female individuals

[...]AF assessment is widely used to characterise participant cohorts, or detect effects of interventions aiming to improve these chronic diseases. To optimise the design of future studies, the present sub-study assessed whether systolic (SBP) and diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) when semi- recumbent, and after 1 and 2 minutes of standing, were similar PRE and POST (assessed using an automated oscillometric device). [...]circadian fluctuation in these do not appear to differ between sexes (3). [...]other factors, such as relaxation status and glucose ingestion, may be implicated in changes observed at POST.
