Do You Have a Maximum Heart Rate?

The video explains how heart rate increases during exercise to meet muscle oxygen demands. It discusses the concept of maximum heart rate, which is influenced by age and the nervous system. The heart's contraction speed is limited by the time needed to reset after each signal, preventing it from reaching its theoretical maximum rate. Exercising within a target heart rate zone, typically 50% to 85% of the maximum, is recommended for health benefits without overexertion.
