Treadmills with built-in heart rate monitors allow the user to test her active heart rate without needing to stop using the treadmill. Prior to the invention of the built-in heart rate monitor, treadmill users had to leave the machine and measure the rate manually using a clock and calculations.Continue Reading
To manually check heart rate, one must first check the pulse. To find the pulse, place the index finger and middle finger on the area of the neck immediately to the left or right of the windpipe. Depressing on this area allows one to feel the blood being pumped from the heart through one of the body's major arteries. This rhythmic pumping of blood is referred to as the pulse. To find the heart rate, count the number of times the pulse can be felt during a 15-second period, then multiply that number by four to find the number of times the heart beats in a minute.
Testing the pulse manually while walking or running on a treadmill is both dangerous and inaccurate. As such, built-in heart rate monitors allow treadmill users to measure heart rate with a greater level of safety and accuracy. The most common type of heart rate monitor involves placing the hands around two metal panels to track blood flow.Learn more about Home Fitness Equipment
