Thanks for sharing. For me, I can see that DURING exercise, my blood pressure is quite raised but then drops down lower than usual in the hours that follow. However, I think that's more a function of resting HR - which remains elevated.
My particular BP scenario is good diastolic, high systolic but low rest heart rate (low 50s). My pet theory is that my heart does fewer but stronger pumps, which increases the BP. After exercising, when heart rate remains elevated, the BP is lower since the heart is doing more frequent but less powerful beats.
Just a pet theory, I haven't even discussed it with a medical professional.
