Abstract: In the present study on body function monitoring in training，changes of physiological and biochemical indexes are used in body function monitoring in training.But the approach has serious shortcomings：It cannot systematically analyze influential factors and feedback relationships of these influential factors in body function monitoring of training.According to the principle and method of system dynamics，the system dynamics model of body function monitoring with body function level，training quantity and body resume as dynamical mechanism is constructed.Finally，taking body function monitoring for Chinese badminton athletes for instance，the athletes’ body function level changes are simulated with two parameters.Simulation results show that the first program is a scientific training method for badminton athletes.

Key words: training, body function monitoring, system dynamics, model, simulation
