I need some help in finding the source/study of a method on determining Max HR in an article by Sally Edwards titled, "Missing Your Max?" The method used age and percent of body weight to determine Max HR. It is her "good" method in the article. I've been using it more successfully than the standard 220-age, but my director told me that to continue to use it, I must provide him with the source/study from which the formula was derived. Please help.
I’d like to answer your question about the old formula called “Age Adjusted Maximum Heart Rate Formula.” That formula of 220-age = maximum heart rate has too large an error to be used safely. In response, Heart Zones USA in the early 1990s commissioned a study that resulted in a new formula, the one you have and yes, it is more accurate. However, after administering literally thousands of sub-max tests and comparing the results, I have come to the conclusion that no formula works. So we no longer use a formula because the empirical evidence shows that giving a battery of sub-max tests is the most accurate assessment from a skilled test administrator.
However, you asked for a journal article, and I’d like to refer you to several excellent articles on maximum heart rate:
