How do YOU Finding your Target HR?

**DNoMac** · 06-28-2004, 10:17 AM

I know most people use the simple formula 220-age x workout intensity, but recently I found another one that is more specific to the individual. Have any of you heard or use the Karvina/HR Reserve system? It works like this: 220-age (max heart rate). Then you take your MHR and subtract your normal resting heart rate (RHR), this gives you your Heart Rate Reserve (HRR). Hang with me. With your HRR, multiply with % of intensity then add your RHR, this gives you your new target hear rate. This seems for specific to the individuals cardiorespitory condition. If your in better shape, it should be higher than your THR with the normal formula. What you guys think? Here's just the formula:

220 - age = max heart rate (MHR)

MHR - Resting HR = Heart Rate Reserve (HRR)

HRR x % of intensity + Resting heart rate = Target Heart Rate

I use the Karvonen Formula to calculate mine. There is a good site with details on this and an online calculator too. http://www.fitzones.com/members/Fitn...rate_zones.asp

Yeah, the Karvonen formula is better.

I think that may be the same thing, from the formula shown on the website, it looks to be very similar. No more math! thanks doby.

I've never heard of that before, but i'll definately start using it now.....Thanks.

Make sure you get a true resting heart rate or else you'll just add to the error thats already invovled in estimating your max heart of +/- 10 beats.

Yeah, the best way to get your resting HR is to check it in the mornings before getting out of bed. I do this most mornings as the resting HR can also help determine over training.
