Abstract: Based on the 3H theory of back style high jump, 47 students majoring in physical education adopted the method of comparative experiment. Under the condition of similar physical quality and body shape, the same approach and take-off technique and take-off and push out technique were used in the teaching. Through the standing take-off and landing pad practice in the experimental group and heightening the take-off and landing pad practice, the hip and waist of the students were lifted to delay the free fall and create more space time. The perception time of air movement is long, and the auxiliary teaching design of students' passing pole technique is strengthened. It is found that the assistant teaching method can improve the technical performance of high jump through the improvement of passing pole technology. This optimization is reflected in the improvement of the utilization rate of jumping height, which is of positive significance for students with the same height of body center of gravity to improve the performance of high jump and technique.
