The relationship between ambulatory blood pressure and physical activity in young and older shiftworkers : a quantitative assessment of physical activity using a microcomputer with acceleration sensor.
We studied the relationship between physical activity and ambulatory blood pressure (BP) in young and older shiftworkers by simultaneous recordings of activity, blood pressure and pulse rate (PR).
Activity was assessed using Activetracer, a self-contained microcomputer with an acceleration sensor, attached to a waist belt.
Ambulatory BP was monitored every 30 minutes for 48 hours with a TM2421.
Three types of hemodynamic responses were noted in relation to the physical activity.
The balance type, in which both BP and PR increase with physical activity, was observed in 5 of 10 young cases (50%) but only in 1 of 7 older cases (14.3%).
