Abstract: Objective: To investigate the effect of biofeedback method on the training of diving technique through experiment. Methods: Twenty junior divers from Team Beijing were selected as subjects. The athletes were randomly divided into experimental group and control group. A three-dimensional dynamometer was used to test the general bounce ability of the two groups of athletes before, during and after the experiment. The biofeedback system was used to test the effect of their special bounce ability, the new and the old diving techniques. The experimental group used biofeedback system to assist their training, while the control group did not use biofeedbacksystem under the same training conditions. Results: There was no significant difference between the experimental group and the control group in the three-dimensional dynamometer test(P>0.05); The ability of the experimental group was significantly higher than that of the control group in special jumping, learning new diving techniques and consolidating old diving techniques(P<0.05). Conclusion: With the same general springing ability, The biofeedback method effectively improves the special take-off height of athletes, and has a positive impact on the athletes' take-off techniques; The biofeedback method improves the take-off height of the new techniques of the diver, and the performance of the diver was remarkably improved; The biofeedback method has a significant effect on the latter stage of the old movement of divers; Springboard diving biofeedback system makes the diving training more efficiency, however, its effect is also affected by multipul factors.
