Heart rate variability can be a useful tool for maximizing your training, according to studies. Your HRV will drop after several days of intense exercise.
Subtract your age from 220 to get a ballpark idea of your maximal age-related heart rate. For instance, the predicted maximum age-related heart rate for a 50-year-old person would be computed as 220 - 50 years = 170 beats per minute (bpm). The 64% level is 170 x 0.64, or 109 bpm, and the 76% level is.
The medical word for a heartbeat that is greater than 100 beats per minute is tachycardia. Tachycardia can be brought on by a wide variety of heart rhythm abnormalities (arrhythmias). A rapid heartbeat doesn't always indicate danger.
