I've been a bit puzzled by what I consider an anomaly in me.
I will generally see a fairly steady climb in heartrate as I increase exertion, from below 100 until I hit about 130. Once there my heartrate seems to jump to the high 140s (145 and above) without any 'climbing' thru the 130s and low 140s. If I ease, I again skip that range and quickly drop to 130 or below.
I've actually tried to ride a pace that would have me in that 'bermuda tirangle' of heartrate and rarely do I ever see a number in there. There were a couple of really forced sections where I'd ease and increase just to keep 133-134 steady - can't remember if I've ever seen a steady 138 or 140 - don't think so. I honestly don't remember if that was the case back in the 90's, but definite since my re-entry in Spr'05.
Anyone else have that kind of thing happening?
Any thoughts on whether thats unusual? Alien Lifeform?
just olde phart-age happening?
