Heart Rate

I have known for a long time that heart rate always lags behind but I always took that to mean that it takes a few seconds for it to pick up when you increase effort. I have never heard of a delay of a whole day!

But that seems to be what was happening during my last cold. I already had a sore throat and a slight headache on the first morning but the HR was still fine for one more day. The same then happened in reverse. On Friday I felt pretty much fully recovered but the HR was still elevated when I was running that morning. It took another full day for the changes to show up on the HR chart on Saturday morning, when I finally posted some decent figures (mind, they're still 10 beat higher then where they should be once I reach proper fitness). There is no need to get carried away, though - the HR was higher again this morning, despite me running the same route in pretty much the same conditions and at the same subjective effort level - sometimes I really don't know how this works on a physiological level.

But the cold (or even colds) is finally behind me and I can breathe easily again, literally. Now I'm looking forward to the numbers to improve, though that will require some patience.

Oh, and I bought a new toy. Measuring resting HR in the morning is something I don't do very often, mostly because putting on the chest strap and then setting up the watch is a bit of a pain first thing in the morning. So I bought a little contraption that can measure HR right at your finger tip. Much easier! I could follow the progress of my recent cold that way, with the resting HR at about 55 when it was at its strongest and now back to 49 on Saturday and 48 on Sunday - the level I would expect when not fully fit. Of course it's not medical grade but it suits my needs and for £12 it was very reasonably I thought.

So, right now I'm running 7 miles each morning, which takes me just under an hour, and I'll probably stay at that for a bit now. It should hopefully be enough to build up my fitness to the next level but there is still a long way to go before I get back to where I used to be,
