It has nothing to do with running. That was just the first website I found on the subject. There are many, many more that say the same thing. Your MAX HR will be higher while running, but the formulas are the same.
Here is a good calculator that shows the zones corrected for resting HR.

If you want to fine tune your training doing a field test to determine your actual LTHR or functional threshold is a lot more precise than HR zones based on calculations from maximum HR.
