So I’ve taken the plunge. I’ve got the heart rate monitor and have it all ready to go. This will be the answer to improving my cardiovascular fitness. All I have to do is plug my target heart rate zone into the monitor, slap it on and stay within my zone while I exercise. Simple. Or not.
I’ve figured out my THR a couple different ways, using some of the methods from the web sites I’ve cited earlier. Using the basic age calculation plus fitness level, I get a range of 98 to 131. http://exercise.about.com/cs/fitnesstools/l/bl_THR.htm
This still seem a little low on the low end, but the higher end sounds better.
Then I try the Karvonen formula and get a range of 130-147.
http://www.thewalkingsite.com/thr.html Hmm. Now the bottom of the range seems too high.
Then I find a mystery web site (which I’ve not been able to find since) that calculates by some unknown method, and gives me a range of 126-152. The plot thickens.
Then, I let my HRM calculate the range for me using what it calls the OwnZone feature, and get a number of 119-139.
So, which one should I use. I decide that I’m pretty fit, so I throw out the numbers under 110. I decide I’ll try working in a range of 130-145, which according to the Karvonen formula and the mystery web site, should put me in the 60-70% of my THR range.
I’ll let you know how it went.
