In volleyball serve technology, the more stable the athlete, the more cunning the serve landing point, the stronger the offensiveness, and it is possible to directly break through the opponent's defense in the volleyball game and score directly. For students at the high school level, the various functions of the body are in a period of rapid development, and how to enable students to master special skills is the current key research topic in the field of physical education. The cultivation of interest in physical education learning plays an important role in the overall development of students. In the physical education curriculum at the high school level, most of the learning of volleyball hands-on serve is limited to preliminary contact, and the teaching method is single, resulting in many students repulsive psychology in the process of learning volleyball to serve the ball, and the learning effect is not good. When learning high technical difficulty of the action, the student's learning effect reaches the bottleneck period, the use of appearance training method, theoretically can help students efficiently complete the expected action, visualize the difficulty of the serve, but also enhance the student's interest in participating in sports activities, improve the student's appearance ability, so that students master a better volleyball hand serve ability, more willing to participate in volleyball sports.

Research Objectives: The purpose of this paper is to verify the influence of appearance training on the teaching effect of volleyball serve by developing appearance training methods and performing appearance intervention in physical education class for first-year students whose physical fitness development is at an important age of succession, and to provide a teaching method basis for improving the efficiency of high school students learning volleyball to serve and their interest in physical education.

Research Methods: 20 male students in the first grade of Angang Senior High School in Anshan City (height 176±6.97cm, weight 69.28±13.30kg) were taken as experimental objects, and 20 students in the control group (height 175.2±6.90cm, weight 68.45 ± 14.71kg) were taken as the experimental object, and the two groups carried out teaching experiments for 8 weeks, with two courses per week, a total of 16 class hours. Before the experimental intervention, the two groups of students were issued the "High School Students Physical Education Learning Interest Scale" to count the dimensions of the two groups of students' physical learning interest, and the experimental group and the control group of students were tested for basic physical fitness, after the experimental intervention, the volleyball serve success rate, serve landing point score, serve skill evaluation score and physical learning interest of the two groups of students were tested, and the spss analysis was used to compare the relevant data of the two groups of students, and the promotion effect of the appearance training method in the first year of volleyball was tested.

Research results: 1) The application of the appearance training method to the teaching of volleyball hands can improve the success rate of volleyball hands and serves. 2) The appearance training method can improve the control of the serve landing point and the technical evaluation performance. 3) The appearance training method has effectively enhanced the interest in physical education learning. 4) Appearance training effectively improves students' appearance ability.

Research conclusions: 1) Compared with the traditional physical education classroom based on physical training, appearance training can improve the success rate of volleyball in a more systematic and efficient manner. 2) Compared with the traditional physical education classroom based on physical training, appearance training can improve the score of volleyball serve and technical evaluation, compared with the results of the experimental group and the control group, the difference in service evaluation results is obvious. 3) Compared with the traditional physical education classroom based on physical training, appearance training can enhance students' interest in sports learning, and the degree of sports attention is most obvious in the five dimensions of physical learning interest. 4) After the periodic systematic appearance training, the appearance ability of high school students is improved, and the improvement of students' appearance ability is very beneficial for mastering the motor skills of volleyball hands and serves.
