High sustained heartrate = bad/dangerous???
New to the forum and cycling as well. I just purchased a Garmin edge 305 with HRM and went on my first ride with it a couple days ago.
I've been reading a lot about aerobic vs anaerobic workouts and thought I could benefit from toning down my workouts to get in the more 'effective' aerobic zone... However, for my first outing, I wanted to do a 'base ride' and push like I normally do before I change anything up.
I knew I was probably working out in the anaerobic zone in all of my sessions, but the results I got from the unit were pretty staggering (see picture).
My question then, is riding at such a high heartrate level dangerous? I've heard of marathoners who fall over dead from heart problems in the middle of races, and I don't have the greatest genealogical history for heart health either.
My goal with the HRM training was to mix in some aerobic workouts in my routine, but I'd still like to do the all-out ones as well. Is it safe to push yourself so hard, or should I tone it down some even on the 'anaerobic days'???
Thanks in advance for your comments!
Oh, by the way, I'm 6'1, slightly muscular, 245lbs with a resting heartrate below 70bpm - the so called 'clydesdale' variety of endurance athletes
