Listen to Your Heart Resting Heart Rate While Heart Rate is an accurate measure of your performance during aerobic exercise, it is not the only indicator of your fitness level. Your resting heart rate also needs to be determined, especially if you plan to use the Karvonen method (see next page) to ascertain your target heart rate. The resting heart rate represents the minimum number of heartbeats needed to maintain the body. The resting heart rate should be taken first thing in the morning upon waking, and before getting out of bed. Take this measurement after waking without using an alarm that would “jolt” you from your sleep. As you exercise your resting heart rate will become lower because your cardiovascular system will become stronger. From time to time you will need to repeat the above measurement. Step 1: Taking your pulse using the correct fingers Use the index and middle finger to find the pulse. The thumb is has a pulse of it's own that may interfere with the count. Step 2: Locate your pulse Most people find their pulse in the side of the neck or at the wrist. If you are locating it in the side of your neck, be sure not to press too hard or you could block blood flow to one side of the brain. Tilt your head back slightly and place your fingers in the groove that is to the side and slightly above the Adam's apple. If you are trying to locate the pulse in your wrist, tilt the hand back slightly and place your fingers on the thumb side of your wrist. Step 3: Count the beats that you feel The first count begins with zero. Count each successive beat, continue counting for ten seconds. Multiply this number by 6. Step 4: Record the count The Resting Heartbeat number should be somewhere between 45 and 80. Athletes will have a lower resting heart rate while an older person who is inactive will have a higher resting heart rate. The higher resting heart rate does not indicate cardiovascular disease but indicates a lack of aerobic conditioning. Drugs such as caffeine and those found in cold medications raise the heart rate and do not give a true indication of the resting count.
