Why use a Strapless Heart Rate Monitor?
Many people have turned to strapless heart rate monitors to track their improvements in physical fitness. As fitness levels improve, so does your average heart rate during exercise.
The strapless heart rate monitor looks much like a wrist or even clip-on watch and can help you to maintain a target heart rate during a workout, thus maximizing any aerobic workout. Begin by placing two fingers on the heart rate monitor. If your heart rate is 5 to 10 beats lower than it was when you first started exercises, then you heart is working more efficiently during exercise. Conversely, if your heart rate monitor shows your heart beating above your average heart rate for an extended period of time, that is a sign you are overexerting and should slow down.
The Technology
Unlike heart rate monitors that measure impulses by being strapped directly to your chest, strapless heart monitors measure your heart rate by detecting impulses in your fingertip. These impulses are then transmitted to a computer chip located in the monitor and translated into digital readings onto the screen. Unlike heart rate monitors that provide continuous data because they are strapped to your chest for the duration of the workout, strapless monitors only provide information when the two fingers are placed on the monitor.
How Is the Heart Rate Measured
Heart rate is the rate of heart contractions over a given time period, according to HealthCheckSystems.com. Although the readings may not be as frequent a strapless heart rate monitor; strapless versions are said to be as accurate as an electrocardiogram, or ECG, machines in their ability to pick up electrical impulses produced by the heart and read in the fingertips.
