CompuTrainer Results: What does it all mean?!

[Eden]

Your max HR won't change drastically (it will decrease little by little as you age). It's a genetic thing and has little to do with predicting performance. Training zones are based on your max, so this means you can set HR training zones without having to test and reset all of the time.

What will change as you get more fit is your resting HR - this should go down (also handy for keeping tabs on over training. Resting HR's going up are a sign that you need to take a break). Your Lactate Threshold (LT) will also change. (this is the point at which lactic acid builds up and your muscles start to fatigue). Untrained people reach this at around 50-60% of max, but highly trained athletes can get to the point where they aren't hitting it until 85-95% of max.

Soooooo to answer your question... its not your HR per say that changes. You will in fact be able to produce more power at lower HR's as you train, so it may appear that way. You can certainly use a HR monitor to train with. One way to test your fitness with one is to do a short TT - 8 miles or so on the same course every once in a while (even better if you can do it on a trainer) Keep your HR in a specific range - I think it was low zone 4 for me. See how long it take you. You should see yourself getting faster.
