I just read through a flyer for the WIN program and noticed an error in the heartrate-max calculation. Because of the way the original formula was broken down, a sign error turned up. The formula used is much better than the traditional one that usually gives a max that is too low. The correct formula is:
- Heartrate-max = 210 - (age / 2) - (weight * 0.05) (+ 4 if male)
- Heartrate-max = 220 - age
Wednesday evening - I got a call from the WIN for Alaska folks thanking me for pointing out the error. Who else but one obsessed with exercise would be up at 1:00 am reading a flyer on exercisig and testing a formula for maximum heart rate. The phrase "get a life" comes to mind for some reason. I haven't carried my pedometer for months but I suspect the daily step count will be down significantly.
