To investigate physiological changes on cardiovascular regulation in rabbits caused by the influence of disturbances of earth geomagnetic field.
The Kakioka Magnetic Observatory supplied the values of geomagnetic field (GMF) disturbance.
Exposure duration: 50 min
|Exposure duration||50 min|
|magnetic flux density||46 µT||-||cf. remarks||-||to 47 µT; ambient DC GMF in the laboratory|
This study provides evidence that GMF disturbance is associated with (1) weaker baroreceptor function and (2) decreases in spontaneous cardiovascular variability estimated by heart rate variability and blood pressure variability.
