I have this very strong, I think accurate memory of spending a lot of time at or around heart rate 165 when I was training for rowing as a teenager. I credit this approach (with a lot of other coaching wisdom) with winning a junior national championship and an olympic festival.
I just picked up a snipped in Maffetone's e-book on the MAF method:
For athletes 16 years of age and under, the formula is not applicable; rather, a heart rate of 165 may be best.
Very interesting and validating of the memory. I wonder if Todd Jesdale (my coach at the time) had read Maffetone?
