This transmitter is encased in a waterproof chest strap that houses two electrodes. The heart rate is accurately transmitted to a watch- like heart rate monitor that continuously displays the heart rate throughout the time that the student is wearing the chest strap. With the use of the heart rate monitors, it is relatively easy to determine is a student or class of students has exercised in the training zone. It is necessary to train in this zone to achieve cardiovascular efficiency. Once the exercise is completed, the heart rate monitor can be interfaced with a computer.
Information is graphed as well as analyzed.
