Heart rate is simply the number of times that the heart beats per minute.
This is generated by the "pacemaker" of the body which is the signal sent from the brain to the heart's sinoatrial (SA) node. This causes the initiation of contraction of the cardiac muscle which spreads across the heart to contract the atria and ventricles in a rhythmic fashion. The number of times this signal is sent from the brain to the heart gives the heart rate.

The Karvonen Theory, or Karvonen Formula, is a method used to determine target heart rate zones for exercise intensity. It calculates the target heart rate based on an individual's resting heart rate, maximum heart rate, and desired exercise intensity percentage. The formula is: Target Heart Rate = [(Maximum Heart Rate - Resting Heart Rate) × Desired Intensity] + Resting Heart Rate. This approach helps tailor cardiovascular workouts to optimize fitness benefits based on personal heart rate levels.
