Hi. I'm 39 and have been involved in fitness/athletics most of my life. I have noticed a phenomenon from time to time, most recently the last couple of days. My body normally can do a given (exercise) routine and follow a pretty consistent HR pattern. However every once in a while, like last night, my HR gets higher, much more easily and quicker. Other than things like dehydration (which I wasn't), what can cause this? Does anyone else here experience this too?
For what it's worth I actually took it easy last week. I'm wondering if not doing much intense cardio for one week could cause me to be less fit? Seems hard to believe that one week could do that, especially given that it wasn't 1 week of doing nothing. I walked, played tennis, did very slow paced bike rides, etc.
Thanks,
James
