Final Exam Study Guide Set #1: Heart Rate Score ________ /10 Name _________________________ Hour _________ What should you know about your heart rate? Even if you’re not an athlete, knowledge about your heart rate can help you monitor your ______________ — and it might even help you spot developing ______________________. Your heart rate, or pulse, is the _____________________________________________. Normal heart rate varies from person to person. Knowing yours can be an important heart-health gauge. “As you age, changes in the rate and regularity of your pulse can change and may signify a heart condition or other condition that needs to be addressed,” said Richard Stein, M.D., professor of medicine and cardiology at the New York University School of Medicine in New York City and a volunteer for the American Heart Association. Where is it and what is a normal heart rate? The best places to find your pulse are the: 1. __________________ 2. __________________ 3. __________________ 4. __________________ To get the most accurate reading, put your finger over your pulse and count the number of beats in 60 seconds, Stein said. Your resting heart rate is the _________________________________________________________________________________. If you’re sitting or lying and you’re calm, relaxed and aren’t ill, your heart rate is normally between 60 (beats per minute) and 100 (beats per minute), Stein said. But a heart rate lower than 60 doesn’t usually signal a medical problem. It could be the result of taking a drug such as a beta blocker. A lower heart rate is also common for people who get a lot of _____________________ or are very ___________, Stein said. Active people often have lower heart rates because their heart muscle is in better condition and doesn’t need to work as hard to maintain a steady beat. “Moderate physical activity doesn’t usually change the resting pulse much,” Stein said. “If you’re very fit, it could change to _____. A less active person might have a heart rate between ____ and _____,” he added. That’s because the heart muscle has to work harder to maintain bodily functions, making it higher.

Keeping tabs on your heart rate can help your doctor determine whether to change the dosage or switch to a different medication. “If your pulse is very low or if you have frequent episodes of unexplained fast heart rates, especially if they cause you to feel weak or dizzy or faint, tell your doctor, who can decide if it’s an emergency,” Stein said. “Your ____________ is one tool to help get a picture of your health.” Blood Pressure VS Heart Rate Blood Pressure What is it? What is the unit of measurement? What do the numbers represent? Sample reading Heart Rate Here are some more things to know about the correlation between blood pressure and heart rate. ___________________________________________________. Measuring pulse rate does not indicate high or low blood pressure. For people with high blood pressure, there's no substitute for measuring blood pressure. _________________________________________________________________. Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily. When you exercise, your heart speeds up so the blood can reach your muscles. It may be possible for your heart rate to double safely, while your blood pressure may respond by only increasing a modest amount. ___________________________________________________________________ _________________________________________________________________. If you take your pulse (measuring your heart rate) before, during and after physical activity, you'll notice your pulse will increase over the course of the exercise. The greater the intensity and the more energy the activity demands, the more your pulse will increase. When you stop exercising, your pulse does not immediately return to normal; it gradually returns to its resting level. The greater your fitness level, the sooner your pulse rate will return to normal. These numbers may be helpful to understand but they are not linked to your blood pressure. Learn about your target heart rate during physical activity and how to monitor it. GETTING IN THE TARGET HEART RATE ZONE What's all this fuss about target heart rate, you ask? Well, we know to improve our cardiovascular endurance we must perform ___________________, right? But there is a little more to it than that. We need to get our heart rate up into the desired target heart rate zone for a ______________________________ in order to utilize the overload principle and to lead to substantial fitness improvements over time. ACSM (American College of Sports Medicine) says we need moderate-intensity exercise (4060% of HRR) for at least ___ minutes on ___ or more days a week, for a total of _____ minutes per week, or vigorous-intensity exercise (60-85% of HRR) for at least _____ minutes on ___ or more days a week for a total of ____ minutes per week. For weight loss, _____ minutes per day to a total of ______ minutes moderate exercise is recommended. WHAT IS YOUR OPTIMUM EXERCISE INTENSITY? Studies show that optimum exercise intensity for fitness improvement is in the range of about ____% to ____% of (HRR) heart rate reserve. Of course, the fitter you are, the higher the appropriate exercise intensity. Very deconditioned individuals may begin to improve at about ________% of HRR. Calculating YOUR Target Heart Rate Range Purpose: To identify a PERSONAL target heart rate zone; which is a safe and comfortable level at which to perform physical activities. Procedure: Study the example provided before completing this activity EXAMPLE For You LOWER LIMIT Start with 220 Subtract your age Equals MAXIMUM heart rate (MHR) 220 -20 - 220 _____ UPPER LIMIT - 220 _____ 200 Maximum times heart should beat/min Subtract YOUR resting heart rate Multiply by: 60% - Lower Limit 80% - Upper Limit Add resting heart rate Equals Target Heart Rate (THR) -70 130 x .60 78 + 70 148 130 x.80 104 + 70 174 Beats per minute ______ X .60 ______ + ______ Beats per minute ______ X .80 ______ + ______ Beats per minute Your Target Heart Rate Zone 1.
