Hi Bobby

Could you explain Baroreflex please?

Craig here a  simple definition of this  possible  question.
 

The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure reflexively causes the heart rate to decrease and also causes blood pressure to decrease. Decreased blood pressure decreases baroreflex activation and causes heart rate to increase and to restore blood pressure levels.

 

Baroreceptors are special receptors that detect changes in your blood pressure. Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.

Hi Craig,
It was a simple squat exercise using body weight only.... you may also need to play with upper body "position" with the aim of increasing internal blood pressure as you perform the squat. Each dip in SmO2 is a single squat.

The first SmO2 dip did not have the same baroreflex effect [smile]

Thanks Juerg. So Bobby you were basically manipulating your blood pressure.
