Name________________ Intro to Fitness Target Heart Rate Worksheet Hearts in Motion Each individual has a rate at which his or her heart beats. The beating of your heart is called your pulse. When you are resting, your heart rate (pulse) will be different from what it is when you are exercising. You can check your pulse by placing your fingers in certain places on your body. Many people are able to feel the pulse on the insides of their wrists. Your thumb can be used to support the back side of your hand. If you are unable to feel a pulse from this vein, you may want to try the artery in your neck. To find this artery, gently place the same two finders in the middle of your neck. Then move them to either side of your neck about one inch. You should feel a pulse in this position. It is important that you not press too tightly in this area. Once you are able to feel your pulse, you should be able to find out what your resting heart rate is and what your heart rate after exercise is. Have a partner assist you by keeping time for you. You will want to count the number of pulse beats that you feel during a one-minute period of time. First, you should take your pulse while sitting at your desk. Record your resting heart rate below. Next, jog in place for a few minutes. Now take your pulse again. Below, record your heart rate after exercising. Resting heart rate:____________ After exercise heart rate:______________ Answer the following questions: 1. When did your heart beat the fastest? ____________________ 2. What was the difference between the two heart rates?______________________________________________ 3. Does exercise increase or decrease the rate of your heart beats?______________________________________________ 4. Why do you think it is important to increase the rate of your heart?______________________________________________ Name________________ The Target Zone There is an amount of exercise which is enough to condition the muscles and cardiovascular system leading to physical fitness, but us not overly strenuous. There is a target zone in which there is enough activity to achieve fitness, but not to much to exceed safe limits. Each individual’s target zone is between 60 and 80% of his or her own maximum heart rate. Below 60% of his or her capacity, he or she achieves little fitness benefit. Above 80%, there is little added benefit from a great deal of exercise. To determine whether you are in the target zone, learn to count your pulse. It is important to count the pulse immediately upon stopping exercise because the heart rate changes very quickly once the exercise is stopped or slowed. Fine the beat within a second and count for 10 seconds and multiply by 6 to obtain the count for one minute. Five minutes after exercise the pulse should be at or below 120; ten minutes after exercise it should be at 100 or below. If it isn’t, the exercise was perhaps too tough. There is a relationship between age, resting heart rate and maximal aerobic power. The following formula can be used to determine your target zone. You can use this worksheet to compute the minimum and maximum heart rate range you should aim for during aerobic fitness activities for beneficial training effect to occur. It is recommended that you work somewhere in your lower range during the first month of exercising. My age is:_______________ My maximum target heart rate is 220 – Age = __________ Formula ____________ X 60% (.60) = _______________________ (Maximum HR) (Minimum Working HR) ____________ X 80% (.80) = _______________________ (Maximum HR) (Maximum Working HR) My Target Heart Rate Range is __________ to ___________ (Minimum) (Maximum)
