A normal heart rate is between 60-100 beats per minute at rest (sitting, relaxing, etc.). It is well-known that the average resting heart rate for well-trained athletes is 40-60 beats per minute! However, this rate can change dramatically while sleeping or with daily activity and exercise.
Most texts cite the typical resting heart rate in adults as 60â100 beats per minute (bpm). A large body of evidence indicates that the normal range is actually 50-90 beats per minute. For example, all-cause mortality is increased by 1.22 (hazard ratio) when heart rate exceeds 90 beats per minute.
