Ambulatory blood pressure monitoring : effect of physical activity
The present thesis deals with the effects of physical activity and body posture on ambulatory
BP and systemic haemodynamics in normotensive and hypertensive individuals. The Activity
Monitor, i.e., the method used to measure physical activity and posture, is the constant factor
in the presented studies. The Activity Monitor is a combination of acceleration sensors
mounted on the trunk and legs, a portable data recorder, and analysis software. With this
technique, which has been validated in previous studies, physical activity can be quantified
and posture (lying, sitting, standing) and type of activity (e.g., general movement, walking)
can be automatically detected [56,57]. The method used to measure BP varies between the
presented studies. BP was measured intermittently and non-invasively in studies aiming to
improve interpretation of ABPM in clinical practice, whereas BP was measured continuously
and invasively in studies aiming to determine in detail the effects of physical activity and
posture on BP and systemic haemodynamics
