How to improve the physical quality training of primary school students is one of the important purposes of physical education in primary schools. Physical quality training can improve students' understanding of physical education, give full play to students' subjectivity in teaching, and enable students to learn the methods of exercise; Promote the normal development of primary school students, improve students' physical and mental health, enhance physical fitness and improve the level of physical function; Promote the development of students' conscious enthusiasm and innovative ability, and establish a correct concept of sports; Enable students to exercise independently and scientifically without the guidance of teachers, thus forming the habit of long-term exercise. Giving full play to students' subjectivity and effectively mobilizing their enthusiasm at different levels will directly affect the long-term effect of classroom teaching and the improvement of students' physical quality. Then, how to give full play to students' subjectivity to improve the physical quality training of primary school students? ?

First, strengthen the importance education and clarify the significance of physical fitness exercise?

In teaching, students should be fully aware of the significance of physical exercise and the long-term value of physical growth. Teachers should tirelessly instill the idea that physical training plays an extremely important role in students' success, stimulate students' interest in physical training, and let students know the purpose of physical exercise, so as to turn boring and monotonous exercise into students' conscious behavior, actively obtain ways and means to participate in exercise, and improve students' subjective consciousness and participation consciousness. Therefore, with the changes of living conditions, environment and age, we can reasonably adjust the fitness exercise items, exercise time and exercise amount, improve the fitness exercise effect and achieve the purpose of lifelong physical exercise. ?

Second, stimulate students' interest and arouse their enthusiasm to participate in practice?

In the physical quality training of primary school students, it is very important to stimulate the enthusiasm of students to participate in practice, so it is very important to cultivate students' hobbies. To insist on physical quality training, we must fully mobilize students' initiative and consciousness. Therefore, physical education teachers should be good at discovering students' interests and hobbies, pay attention to taking various measures, and cultivate, protect and mobilize students' enthusiasm for participating in physical quality training in various ways. Deal with the contradiction between completing teaching tasks and stimulating students' interest in physical education, so that students can get full emotional experience, feel physical and mental satisfaction and appreciate the fun of physical quality in teaching and exercise. ?

Third, pay attention to students' development and attach importance to students' dominant position?

Physical education teachers in primary schools should try their best to guide students how to learn, construct students' dominant position based on the theory of subjectivity education, embody the teaching concept of taking students as the main body, respect students' individuality, acknowledge students' individual differences and attach importance to students' individuality development. The content of physical quality training should be conducive to students' active, lively, vivid and healthy development, and teachers should play a leading role in teaching, combining the leading role of teachers with the subjectivity of students. Teachers should make full use of students' collective thinking and unity and cooperation to create a teaching environment that can give full play to students' subjectivity; Teach students in accordance with their aptitude, guide them by classification, and select and determine different technical details that are in line with students' reality on the basis of different sports; Teaching objectives, teaching difficulties, teaching methods and evaluation criteria make every student operable in learning and exercising, so as to learn something and achieve the goal. ?

1. Give students the right to choose their own physical training content. Active choice brings active learning, provides students with the content of physical quality training, and ensures students' independent choice and all-round development. Students' bodies vary greatly and their interests are extensive. Let the students choose the content and form of practice independently and practice independently. For example, strengthening leg strength can be arranged as follows: deep stairs crossing, continuous obstacle crossing, three, five, seven and other multi-stage frog jumps, distance jumps, one-leg jump relay, long jump, counting rope skipping competitions, timed rope skipping, rope skipping relay, negative light squat jump and semi-squat jump. Give students specific indicators and let them choose a stage of practice to achieve this goal. After the stage of practice, teachers test students' self-exercise scores in time, understand students' indicators, praise the advanced, spur the backward, and create a good competitive atmosphere of "catching up with learning to help the super", thus mobilizing students' initiative in learning, and finally enabling students to learn to choose, form personality and experience the happiness of growth. ?

2. Give students some opportunities to experience the happiness of success by themselves. Experience is a process in which students gain perceptual knowledge through their own activities. Therefore, the content of physical quality training should be suitable for students' physical and mental characteristics, take care of students' sports interests and meet their sports needs. Emphasize asynchronous teaching, treat it differently, and strive to let each student have his own learning goals and opportunities for self-realization. ?

3. Create some difficulties for students, let them find ways to solve problems and cultivate their innovative ability. The new curriculum attaches great importance to improving students' mental health and social adaptability. It is emphasized that in the process of experiencing setbacks and overcoming difficulties, it is necessary to improve the ability to resist setbacks and adjust emotions, cultivate strong will quality, and enhance self-esteem and self-confidence. In quality training, some exercises themselves contain some problems, so that students can find problems in the exercises and help them guide the ways to solve them. Therefore, teachers should pay attention to the close relationship between teachers and students, communicate with students heart to heart, and be students' intimate friends. When students encounter difficulties in study and exercise, we should pay more attention to them, encourage them and enhance their confidence and courage to overcome difficulties. Classroom teaching should adopt inquiry learning, research learning, experiential learning and other ways to stimulate students' interest and enthusiasm in learning, so that students can master knowledge in various learning methods and cultivate their innovative ability. Students will also consciously strengthen the exercise in and out of class and consciously improve their self-exercise ability. ?

4. Strengthen theoretical knowledge teaching and cultivate students' lifelong sports consciousness. In primary school physical education teaching, we should focus on teaching students the basic theory and scientific knowledge and methods of physical quality training, which can take the form of special lectures or be interspersed in the technical teaching of middle schools in physical education class, and we should also arrange certain theoretical class hours every semester; In the arrangement of content, we should be able to inspire students' thinking, arouse students' desire for exercise, and cooperate with the teaching of technology and skills, so that students can develop the consciousness, habits and ability of lifelong exercise and achieve the goal of lifelong benefit. ?

Fourth, attach importance to information feedback to stimulate students' enthusiasm for continuing exercise?

In teaching, teachers should keep abreast of students' exercise situation and make a correct evaluation of students' exercise attitude and performance. This will help to stimulate students' desire to further adhere to their goals and their enthusiasm for continuing to exercise. For example, endurance quality training, giving students specific indicators, requires a stage of practice to achieve this goal. After the stage practice, teachers should test students' self-practice scores in time, understand the completion of students' indicators, praise the advanced, spur the backward, and create a good competitive atmosphere of "catching up with learning and helping the super", thus promoting the progress of all students. ?

After adopting the above methods, some students still attend classes as usual after illness and injury, and can exercise according to their own conditions, so that students' passive training can be turned into active participation, students' subjectivity can be effectively brought into play, and their enthusiasm and consciousness in learning can be fully mobilized, so that all students can be fully developed in physical fitness, organizational ability and technical skills. Therefore, in primary school physical education teaching, we should give full play to students' subjectivity in physical quality training, effectively mobilize students' interest in exercise at different training levels, change students' passive training into interest exercise, and change interest exercise into interest exercise, so as to steadily improve students' physical quality level. After students enter the society, interest sports will become fitness sports, which will certainly promote the formation of students' lifelong sports consciousness and form the habit of lifelong physical exercise. ?
