I don’t know much about how heart rate works -
After doing SSB1 for 6 weeks I created the following plot in excel to compare my before and after ramp test results. I was a bit surprised during the 2nd test I blew up 7bpm lower than my previous test but managed to get further into it
I created a scatter plot then and found the 2 HR curves were modeled well by parabolas of the same curvature only a different height offset (of about 10bpm)
Does anyone know, does this means my stroke volume has gone up? My only concern is that I couldn’t reach the same Max HR, and my ‘threshold’ heart rate seems to have actually decreased (180 to 175) while my FTP went up (269 to 278), does anyone know if this is normal?
