And then what we'd like to see is the heart rate fall by at least 20 beats per minute during that first minute after exercise. That would take us down to 150. People with an abnormal heart rate recovery, the heart rate only falls by a little bit during that first minute after exercise. They were the ones who were at really high risk for subsequent death.
Interesting. The data is for average 50 year old man without particular training. 20 beats a minutes certainly indicates a very low fitness level. I wouldn't exercise very hard if I had that type of recovery rate. I am sure that a 50 year old serious rider can do a lot better than that.
