 Heart rate refers to the speed of the heartbeat, specifically the number of heartbeats per unit of time. The heart rate is typically expressed as beats per minute (bpm). The heart rate can vary according to the body's physical needs. Activities that can provoke change include exercise, sleep, illness, and drugs.beats per minutephysical

 The normal human heart rate ranges from 60–100 bpm.  Heart rate is measured by finding the pulse of the heart.pulse

 Your resting heart rate is the heart pumping the lowest amount of blood you need because you’re not exercising.  Resting heart rate is dependent on your living habits and a number of factors such as quality of sleep, stress level, exercise and eating habits.

 Children 10 years and older, and adults (including seniors): beats per minute  Well-trained athletes: beats per minute

 Wrist (radial artery)  Place the tips of your index and second finger on the palm side of your other wrist, below the base of the thumb. Press lightly with your fingers until you feel the blood pulsing beneath your fingers. Use a watch with a second hand, or look at a clock with a second hand.  Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate per minute. Counting for 1 minute gives the most accurate.

 NECK (carotid artery)  Place the tips of your index and second fingers on your lower neck, on either side of your windpipe.

 The highest rate at which a heart should beat in a minute when people are engaged in exercise  To calculate your average maximum heart rate:  220- age=  Example… =205  205 bpm for a 15 year old

 A heart rate that is attained during aerobic exercise and represents the minimum level of exertion at which cardiovascular fitness can increase for an individual in a given age group.

 To determine your target heart rate, find your maximum heart rate, then take a percentage of it (50 to 85 percent, depending on fitness level).  Example… = 206 (MHR) 206 x.50%=103 bpm (beginner) 206 x.85%= 175 bpm (advanced) Recommended target range= bpm

Age Maximum heart rate (220-age) Minimum target for 60 sec (50% of max heart rate) Maximum target for 60 sec (85% of max heart rate)
