LED indicator for heart rate monitoring system in sport application

This paper presents a current invention for monitoring the athletes´ heart rate during training or exercise session. A bracelet with different color code of Light Emitting Diode (LED) is designed as a wrist heart rate monitor. This color-coding makes the heart rate easier to monitor and enabling the user to know their heart rate range at a certain moment. Our works investigate the used of Zigbee and ANT+ as a transmission medium from transmitter (chest strap) to receiver (bracelet). Different colors signify different ranges of heart rate. Preliminary result demonstrated that it is very helpful for athletes and coaches to monitor the fitness level of athletes and regulate their exercise training regime in a more effective and safer manner.
