I have a type of anaemia, called thalassemia, a not too uncommon blood disorder which reduces the oxygen carrying capacity of the red blood cells. Therefore, when I exercise I have slightly elevated heart rate.
I am sure people here heard of the heart rate zones. My problem is that when I exercise, I immediately hit to the anaerobic zone. If I am not careful, I can easily reach the maximum effort zone. However, I know that I am not really in maximum effort, because no one should be able to endure "maximum effort" for 50 mins. Also, I know that I am not really in "anaerobic zone", at least not 100% of the time, because anaerobic exercise for 50 mins should result in muscle aches due to the lactic acid build up.
I am checking up on my heart with a medical professional so you can assume the way I exercise is healthy for me. (But not necessarily to anyone else in this condition, so if you have a similar condition, do not assume that high heart rate exercise is okay for you.)
My questions is this: Is there a tentative way to know which zone I am in other than heart rate?
