Heart Rate Monitoring OPTIONAL
The Sport Trainer treadmill offers a wireless heart rate monitoring device to give you feedback on how your body is affected by your workout. We will take a look at a few basic concepts of heart rate monitoring so you can better understand how it all works and how to maximize its use to allow you to reach the fitness level you desire.
What
is
exercise
intensity?
Exercise intensity is simply a measure of how hard you are working at a given time during exercise. The American College of Sports Medicine (ACSM), the world’s leading medical and scientific authority on sports medicine and fitness, recommends that every individual involved in an exercise program know how hard his/her body is working during exercise.
Your heart provides key information for determining how intensely you are working during exercise. Your heart rate (how many times your heart beats per minute) is really an efficiency rating for your entire body. The number of times your heart beats during each minute of exercise is a measurement of the intensity of the exercise. If your heart rate is low, exercise intensity is low; if your heart rate is high, your exercise intensity is high.
What
is
maximum
heart
rate?
Maximum Heart Rate (MHR) is the maximum attainable heart rate your body can reach before total exhaustion. True maxi- mum heart rate is measured during a fatigue or “stress” test. This test must be done in a clinical setting and is not practical or accessible for most people. Fortunately, your maximum heart rate can be established with a high degree of accuracy using the following simple formula:
Estimated Maximum Heart Rate = 220 minus your age.
If John is 35 years old, what is his estimated maximum heart rate?
John’s Estimated Maximum Heart Rate =
220 -35
185
WARNING: The use of this formula assumes no underlying heart or respiratory disease or other condition,
which could be adversely affected by exercise. Consult your doctor before using this chart!!!
185 beats per minute is the estimated maximum number of times John’s heart can beat before his body would fatigue or “max out.” This number is extremely helpful because it tells us the absolute highest exercise intensity John can handle before his body wears out. The ACSM says that during exercise, John should keep his heart rate below his maximum so that he will not become exhausted and have to quit. In fact, the ACSM gives John a specific percentage range of his maximum heart rate to exercise in, known as his Target Heart Rate Zone.
