Formula Used
Primary Tanaka estimate: maximum HR = 208 − 0.7 × age.
Model assumptions: Alternative equations are shown for comparison; individual maximum heart rate can differ substantially.
How the formula is applied
The calculation links Age, Gender and Fitness level to maximum heart rate. The primary estimate uses the stated Tanaka equation. Alternative formulas are comparisons, not multiple measurements of an individual maximum. Model convention: Alternative equations are shown for comparison; individual maximum heart rate can differ substantially.
