[Activity balance in behavioural inhibition and behavioural approach systems and rest blood pressure in humans].
The study determined the contribution of activity balance of the two motivational systems, i.e. appetitive and defensive, into mechanisms of blood pressure (BP) regulation in humans. Average age of participants was 30.29 +/- 9.8 years. Men having the BP within normal range and the individuals with firstly diagnosed increased arterial blood pressure up to abnormal values were selected. Using the method of emotional modulation of the startle reflex (EMSR) by different profiles of the EMSR. The participants with shifted balance toward enhanced activity of defensive system (amplified probe startle by unpleasant context) or shifted balance toward low activity of appetitive system (decrease or inhibition of the probe startle by pleasant context) had significantly increased BP in resting. Putative mechanisms of the revealed phenomena are discussed.
