What determines vagal tone?
Heart rate is normally determined by the pacemaker activity of the sinoatrial node (SA node) located in the posterior wall of the right atrium.
Normally, at rest, there is significant vagal tone on the SA node so that the resting heart rate is between 60 and 80 beats/min..
How does exercise increase vagal tone?
The reason for using the interval training is an application of the role of the vagus nerve activity. Vagus nerve activity is relaxed to start the exercise, increasing the heart rate. As the exercise load becomes stronger, vagus nerve activity is decreased and sympathetic nerve activity is increased.
Where do you massage the vagus nerve?
You can manually stimulate the vagus nerve by massaging certain areas of the body. A neck massage along the carotid sinus, the right side of your throat, stimulates the vagus nerve. Foot massage can also increase vagal modulation, as well as help lower blood pressure.
