Webb17 jan. 2024 · Resting heart rate typically ranges from 60 to 100 bpm (beats per minute). Athletes often have significantly lower than average heart rates while the sedentary and obese typically have elevated heart rates. Systolic blood pressure is the pressure during heart contraction, while diastolic blood pressure is the pressure during heart relaxation. dwayne lee littleWebbFör 1 dag sedan · The heart rate may be as high as 250 beats per minute, but is usually between 140 and 180 (a normal heartbeat should be 60-100 beats per minute at rest).
