About a year ago I was running about a 8:30 to 9:00 minute mile average, since then I havent been running nearly as much, until about 4 months ago. Starting in Feb. I have been running quite a lot lately( 5 days a week), with really no to little improvement in my mile times(which is currently at around 10:30). I really just chalked this up to being out of shape and kept working on it, until I bought a HRM 2 weeks ago. Ive done about 10 runs on the watch since I got it and my HR is an average of 180bpm with high of 193bpm. Couple of runs being 30 minutes long at 180bpm average. My resting HR is about 50bpm(sitting up watching tv), about 25bpm a minute recovery. Is this normal?
There are a couple of other possibilities other than what has been mentioned.
a) You could have a higher-than-average HRmax.
b) Your device could be giving you false readings.
How do you FEEL when your HR is 180 or 193? The 220-age formula would give you an HRmax of 195. If your max is REALLY 195, and your are REALLY pumping 193 bpm, you should be feeling pretty darn maxed! If that is not the case, then you might want to consider the possibilities I have mentioned.
Years ago, I began a program of training with a HRM. For several months, I stayed carefully within my target zone. My running became slower...and slower...and slower, until finally I had to walk to stay in my target zone. I was worried, so I made a doctor appointment. He found nothing wrong with my heart, except that I was out of shape. Through trial and error, I eventually found out that I have an abnormally high HRmax. The "target" rate that I was training at was so pitifully low (for me) that I actually lost condition while training at that pace. This may or may not be the case with you, Orangetang. But you would do well to investigate and figure out what's going on.
