Best Answer: I will highlight 3 simple and commonly used type of heart rate: Max HR = 220 - age Target HR = (220 - age) % of intensity Resting HR = Measured while awake but still in bed 50 to 80, regular exercise or sportsman = 35 to 50 Average HR for adult = 60 to 90, Average HR for teenage boy or girl = 60 to 80.
Itâs best to measure your resting heart rate it in the morning before you get out of bed, according to the American Heart Association (AHA). For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the personâs physical condition and age. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA. But a heart rate lower than 60 doesnât necessarily mean you have a medical problem. Active people often have lower heart rates because their heart muscles don't need to work as hard to maintain a steady beat. Athletes and people who are very fit can have resting heat rate of 40 bpm.
