Lately i have started experimenting with the use of a heartrate monitor to visualise the dive reflex during a static atempt.
Very interesting to see how the heartrate suddenly drops like a brick round about the struggle phase. Especialy suprised i was about how low it can get. Always heard about it , but not untill you realy see it it comes out of the realm of something theoretical to something in your face.
This made me wonder however, if there is a clear trend in the bloodpressure as well and how this evolves during a static (or other ) attempt.
I can understand an increase at the start during a final big breath and at the end a sudden drop when comming up, but how about in between and how do we translate this trend in physiological events.
Also does bloodpressure relate to how hard you feel your heart beating. Sometimes it feels like it comes out of my chest , while on other days or other phases within an attempt it is not that pressent.
