“…e more similar the peak values of the two curves are, the more the stroke is completed in the same direction and the fluctuation in the power curve, which reflects the kinetic energy loss in the swing process. e zigzagging fluctuation of the speed curve is used to explain whether the force is consistent in the swing process (if there is an obvious fluctuation before the first peak of the speed curve, it indicates that the lead beat is incoherent and there is a phenomenon of repeated force) [13]. In the actual swing application, the occurrence of downward acute Angle shows the existence of reverse power, which is reflected in misleading, limiting power, and affecting the shot timing.…”

In order to solve the heavy work tasks of teachers and improve the efficiency of classroom teaching, a sensor-based intelligent wearable device method is proposed. The method is divided into four stages: generalization-differentiation-solidification-automation. At the stage of generalization and differentiation, teachers should first demonstrate and drill the correct movements and brief notes for attention. It is not appropriate to emphasize the details of movements too much. In the movement exercise of the differentiation and solidification stage, attention should be paid to guiding students to experience the process of coordinating and generating force, and to enhance the experience of muscle sensation and perception. In the solidification stage, students’ mastery of technical movements tends to be stable, and they should strengthen the combination with other mastered technical movements. In this stage, attention should be paid to the cultivation of individual technical style. The results showed that 46% of the students in the experimental group thought badminton special learning was interesting, while only 15% of the students in the control group held the same attitude. 39% of the students in the experimental group thought badminton special learning interesting, and 31% of the students in the control group; in the experimental group, 15% of students thought that their interest in badminton became average after a semester of special courses, while in the control group, 39% students should be interested in badminton. None of the students in the experimental group thought badminton learning was less interesting, while 15% of the students in the control group still felt badminton learning became less interesting. Conclusion. The method can effectively solve the heavy work of teachers and improve the efficiency of class.
