Sports teaching communication method

The invention provides a sports teaching communication method. The method includes the steps that physiological parameters and current environmental parameters of students are obtained through bracelets worn by the students and then sent to a main machine carried by a coach through a wireless communication mode; the main machine displays the physiological parameters or the environmental parameters, and an alarm is given out when the physiological parameters exceed preset values. Communication between the coach and the students can be achieved through the main machine and earphones, and the physiological parameters of each student can be constantly displayed on the main machine to provide convenience for the coach to check out. Not only can accidents be effectively prevented from happeningduring sports training, but also remote monitoring of the students and remote guidance for the students in real time can be achieved.
