Fórmula
Formula: Max HR = 220 − Age. Zone HR = Resting HR + (Max HR − Resting HR) × Intensity (Karvonen method).
Preguntas Frecuentes
What is the Karvonen formula?
The Karvonen formula calculates target heart rate as: Resting HR + (Max HR − Resting HR) × desired intensity percentage. It accounts for individual fitness by including resting heart rate.
How do I find my resting heart rate?
Measure your pulse first thing in the morning while still lying in bed. Count beats for 60 seconds or for 15 seconds and multiply by 4.
Which zone should I train in?
Zone 2 (60-70%) is best for fat burning and building endurance. Zone 4 (80-90%) improves anaerobic capacity and speed. Vary zones for optimal fitness.
