I thought BP needed to be consistently high to cause strokes, and that short duration peaks and troughs were fine. I have very high BP whenever it's measured, but after wearing a 24hr monitor it showed BP to average out and the cardiologist was fine with that.

I've always considered aerobic conditioning to be something that doesn't affect max breathhold directly, but is very helpful in allowing you to handle and recover from a heavy anaerobic training load.
