I’ve noticed something lately whenever I stand up, go up a flight of stairs, or otherwise surge from inactivity to moderate activity:
I feel like I’m going to fall over.
This is new.
However, I remember the last time I was fast and light (about four years ago, I think) I had the same issue. And today as we left Rick Maddox and Dug in the dust as we rode an easy pace up to the top of the Alpine Loop, I asked Rick Sunderlage (not his real name) if the same thing happens to him. It does.
So now I’ve got two questions for all you cyclists for which fitness is not a new sensation:
1. Do you get the same kind of dizziness I’m talking about here?
2. If so, do you know why?
I’ve got this theory, for which I have no scientific research backing me up, on why this is happening: The fitter you are, the lower your resting heart rate. So, if you’re sitting around and your heart is beating at 46bpm, then you suddenly stand up, it takes a moment for your heart to spool up to a rate fast enough for your suddenly-active body to get blood to your noggin.
Am I right? I thought so.
PS: I am going to pick up the Weapon of Choice after work today, and will be doing a shakedown ride tomorrow. I will report my results either during the weekend or on Monday.
