I am a serious road biker. I took 5 years off and put on 80 pounds. Over the last three years I have lost 60 pounds since returning to cycling.
Last year I purchased a HRM that I was sure was defective. About 30-45 minutes into each ride my heart rate would drop about 40 percent instantly and stay that way for 5 to 10 minutes. Finally I went to a cardiologist who ran a thalium stress test and pronounce my heart quite fit. He recommended that I take salt pills during extended exercise since he believed the cause of the heart rate drop was salt loss. This worked the heart rate plunges stopped.
Now, however, I am noticing that after long rides my heart rate will not drop. During the week I like to get 1 to 3 rides in of about 25 miles. About once a month I will ride 50 miles or more.
On the extended rides I have no complaints, no weakness, no dizziness or other problems. But I have noticed that following these long rides my heart rate will stay over 100 bpm for as many as 5 - 6 hours. My normal resting rate is in the mid 60's.
So why wont my heart rate go down? Is this something to be concerned with?
Any advice would be greatly appreciated.
