Body-building class refers to an aesthetic education course which takes the basic training in dance as the main means, combines music, and practices body-building activities according to people's basic posture. The main purpose is to integrate fitness, mental health and bodybuilding, shape beautiful figure and posture, and strengthen physical beauty. Bodybuilding class is a professional course which takes bodybuilding exercises, posture exercises and coordination exercises as the main means to change the original state of body shape, improve the flexibility, control and expressiveness of human motion system, cultivate elegant temperament and educate students in aesthetic education. Students who have undergone systematic physical exercise are generally well-proportioned and well-behaved, walking like the wind, sitting like a clock, standing like a pine, sleeping like a bow, natural and graceful, which fully embodies the students' vigorous vitality. The main contents of the body-building class include body-building training, elementary rhythmic gymnastics (including "handle", "ballet hand position", "basic dance steps" and "waltz combination"), rhythmic gymnastics, aerobics and mat combination exercises.

② Is it necessary for teenagers to go to physical education class to correct humpback?

I have the following views:

(1) Pay attention to the correct body posture. Whether standing or walking at ordinary times, the chest is naturally straight and the shoulders are naturally stretched back. Sit up straight on your spine. Don't bend your head too much when reading and writing, not to mention lying on your desk. People say that "standing like a pine and sitting like a bell" has some truth.

② Strengthen physical exercise. Do a good job in physical education class and recess exercises to promote the development of muscle strength;

③ Do corrective gymnastics on the basis of comprehensive exercise. There are many kinds of corrective gymnastics, including various forms of unarmed exercises and corrective exercises using various sports equipment. Correcting hunchback is mainly to strengthen back muscles, straighten trunk and expand chest.

The skeleton is the support of the human body, and the spine is the central axis, which is formed by overlapping and connecting more than 30 vertebrae according to laws. Normally, it has four physiological bends. Cervical lordosis, thoracic lordosis, lumbar lordosis and sacrococcygeal lordosis. If the spine bends forward too much, it is hunchback. Medical knowledge tells us that early exercise, avoiding fatigue and paying attention to balanced nutrition can delay the aging process. Supplementing calcium and properly basking in the sun will help prevent osteoporosis. Those hunchbacked people should sleep in hard beds and don't put too high pillows. Lumbar back muscle exercise, especially backward stretching exercise, helps to restrain the development speed of hunchback. The specific treatment plan must be examined and diagnosed by a doctor, and then actively treated.

In addition to trauma, there are several situations that can lead to hunchback. One is heredity, and the other is bad habits. Most people's hunchbacks are caused by bad habits. For example, she usually walks with her head down and doesn't pay attention to her posture when sitting. The girl deliberately closes her shoulders and lowers her head to cover up her prominent chest.

To eliminate hunchback, we should pay attention to overcoming the above bad habits. Usually walk and run, look up, lie on the bed or kang every morning and evening, put your shoulders on the edge, lie on your back, hang your head, and touch the ground with your hands backwards (pay attention to safety). You can also do this during the day off. It will get better gradually.

It is best to take a nap for about half an hour. A long sleep is good for restoring physical strength, and a short sleep is good for restoring brain power.

It is best not to lie flat or on your side during a nap. If you just take a nap on your desk in the classroom, you can touch your head, face and hands a little, and don't press your forehead on your hands or arms to avoid blocking the facial meridians. Don't sleep with clothes on, so as not to let out moisture.

Running can be gradual. Never feel particularly tired. Speed should also be based on your own physical strength. Young people can be quite fast. The time can be morning or evening.

Believe in yourself, you will be fine!

③ How to give teenagers the first physics lesson?

The first lesson is not how many body movements you teach them, but to make them fully understand the course and stimulate their interest in it. This is the most important thing in the first class, and it is also the most important content in the first class of all courses.

(4) How can we exercise well?

Bodybuilding is a purposeful and planned teaching and exercise process based on human science, which exercises healthy physique, trains manners and instruments, and cultivates moral quality through bare hands or equipment practice.

First, the content of physical exercise

Physical exercise is a complete and systematic exercise system, and its content is divided into the following aspects according to the parts and functions of exercise:

(A) the correct feeling exercises of all parts of the body

Correct sensory perception is one of the necessary conditions to form and maintain a beautiful figure, including the sensory perception of the head and neck, trunk, upper limbs and lower limbs and the basic posture of standing. It is an indispensable part of physical exercise to experience the muscle sensation necessary to maintain the correct posture of the body and improve the self-control ability of the body through sensory exercises in various parts of the body.

(b) basic form exercises

Basic form refers to the congenital form and acquired form of the most basic body posture. Its exercises include basic direction, basic parts, hand holding posture, hand holding posture and expressive force. In the practice of basic posture and basic parts, the cognition of direction is standardized for the basic parts of feet and hands; In the hand-holding exercise, arrange the exercise content according to the physical condition of ordinary college students and put forward the normative requirements; Unarmed posture exercises, including various basic footwork and arm movements, emphasize the beauty of gestures and are rich in content; The expressive exercise focuses on cultivating people's graceful posture and the ability to express emotions with body movements and facial expressions, which is one of the most important exercises in body exercises.

(3) Basic quality exercises

Basic quality is a necessary condition for controlling and maintaining body posture. In this part, flexibility, strength and coordination are selected, and their exercise methods are classified and introduced.

Second, the characteristics of physical exercise

Compared with other sports, aerobics has different characteristics. Only by understanding these characteristics can we give full play to the role of aerobics, choose training methods purposefully and pertinently, and achieve the purpose of effective fitness.

(a) for employees at different levels.

The content of aerobics is compiled according to the physiological and psychological characteristics of teenagers, taking into account the needs of teenagers at different ages and according to the law of action formation. The content is divided into three groups: high, medium and low.

(2) Effectively exercise all parts of the human body.

Aerobics pays attention to the method of combining the whole exercise with some exercises in content, which is a comprehensive and focused exercise and "carving"

The conditions provided by the human body can not only enhance the control ability of muscles, but also cultivate correct sensory perception, exercise a certain part of the body or develop a certain quality, and further improve the health level of the body while exercising physical beauty.

(C) in line with young people's desire to pursue beauty

It is human nature to love beauty. Nowadays, teenagers demand not only better health, but also more bodybuilding. Physical exercise is to consciously inject the meaning of "beauty" into the exercise, based on human science, and improve muscle control, movement expression, coordination and flexibility through various exercise means and methods, so as to obtain a bodybuilding posture and a healthy body. Satisfy teenagers' desire for beauty.

(4) There are certain artistic requirements.

Physical exercise requires accuracy, coordination, large amplitude, strong sense of rhythm, beautiful posture and music. Both local exercises and overall exercises should fully reflect the rhythm and feeling of beauty, and fully reflect the artistic requirements of dynamic beauty and static beauty in the process of completing exercises.

(5) It can cultivate people's inner temperament. "Sports create human beauty, not only by shaping the body, but also by instilling a cheerful, open-minded, sincere and enterprising spirit into people's hearts through sports, so that people's actions and gestures are full of beautiful charm, thus truly demonstrating the cultural quality of the human body. Generally speaking, teenagers who have undergone systematic physical exercise are not only well-proportioned, but also well-behaved, sitting, standing and walking gracefully, which can fully show their youthful vitality. The physical beauty obtained through physical exercise can reflect a person's mental outlook and temperament, and it is a window to show people's inner beauty.

Third, the principle of physical exercise

Adolescence is at a critical stage of physical growth and development, and it has not yet been finalized. Great plasticity is the key period to form a good figure and posture and improve bodybuilding. Therefore, we should seize this opportunity and follow the following exercise principles to carry out bodybuilding for a long time, systematically and scientifically.

(A) the purpose principle

The enthusiasm of physical exercise comes from clear purpose and correct motivation. Therefore, we should first carry out regular ideological education and link the purpose of physical exercise with improving the quality and national image of the whole Chinese nation and promoting the correct development and health of the body. The determination of this goal is helpful to generate positive emotions and consciously overcome various difficulties encountered in the practice process. Secondly, at every stage of physical exercise, we should strive to achieve the expected goals. Physical exercise is a long-term task, and it is not easy to produce obvious changes in the short term. Therefore, there should be clear purpose requirements in each practice stage, and these requirements should become the expected goals of the practitioners. For example, leg flexibility exercises should aim at vertical and horizontal splits, and each exercise combination aims at mastering movements, thus making practitioners interested in the content. Interest itself will promote practitioners to practice actively. Through the combination of class and class, physical strength and brain power, it will inevitably have a good influence on the body, and then change in body shape and temperament. In this way, practitioners will feel rewarded and play an important role in mobilizing and consolidating the enthusiasm of practitioners.

(2) the principle of proceeding from reality

The principle of proceeding from reality is to make corresponding practice plans and select corresponding practice contents according to the different ages, genders, physical foundations and practice levels of practitioners. So that practitioners can produce effective force in all parts of the body during the practice, and they are not afraid of difficulties and will not be overtired. For example, when dealing with children, we should choose a combination of exercises with lower difficulty-focusing on basic quality exercises, focusing on all-round exercises, and appropriately selecting content with strong gameplay; For teenagers with a certain foundation, we should choose the movements in the middle and high difficulty group-mainly local exercises, mainly carving various parts of the body, and crossing the grip and leaving the grip. At the same time, we should combine general requirements with differential treatment, put forward general requirements for the similarities of people at the same level, and treat everyone's differences differently. Such as the number of exercises, time, feeling of action, etc.

(3) Adhere to the principle of regularity.

When doing calisthenics, we must insist on regularity and perseverance, so that various effective methods in calisthenics can have a lasting impact on all parts of the human body, gradually form a "habit" and make every gesture reflect a "behavioral beauty." Teenagers should have enough time for physical exercise, and qualified schools should set up physical education class at least twice a week to ensure that students have enough time to receive comprehensive and systematic exercise during their school days. This not only helps students to correctly understand the standard requirements of body posture in concept, but also helps students to master the methods and means of physical exercise in practice, and also helps to form biological rhythm, so that the human body can gradually adapt to and prepare for participating in exercise, further improving the effect of exercise, which is of great significance to cultivating students' idea of "lifelong sports".

(4) the principle of gradual progress

In the process of teaching physics exercises, we must follow the principle of from easy to difficult, from simple to complex, and gradually improve the teaching difficulty and requirements. Reasonable and orderly arrangement of contents, methods and exercise load should reflect the objective law of physical exercise teaching process. Specifically, warm-up activities should be carried out before class, and then the content to be practiced should be carried out, so that practitioners can enter the practice in the best state, enhance their acceptance, improve the practice effect, and prevent injury accidents; At the end of the course, there should be relaxation activities or games, so that practitioners can eliminate fatigue as soon as possible and produce happy emotions. For those who have just participated in the exercise, they should pay attention to the content of basic exercises, and gradually put forward new requirements with the continuous improvement of physical fitness and sense of action, and gradually transition to a higher level of action.

(5) the principle of comprehensiveness

Aerobics should comprehensively develop all parts of the body, all kinds of physical qualities and basic activities, and carefully "carve" every part of the human body. Teenagers are in the stage of growth and development, and physical exercise should strive to influence the human body in an all-round way, highlight the key points in different stages and give consideration to other aspects. At the same time, it is necessary to combine physical exercise with the cultivation of inner temperament, so that teenagers can have a correct aesthetic consciousness through physical exercise, even if they are well developed and have an elegant and refined temperament, they can grow up healthily in a beautiful artistic environment, making physical exercise an effective means to improve the comprehensive quality of teenagers.

⑤ What should teenagers pay attention to in physical training?

Cultivating sports interests and habits is the key. Because of the particularity of teenagers' physical condition, regular special sports activities can help them improve their cardiopulmonary function and skeletal muscle health. Regular physical activities can improve aerobic capacity, muscle strength, bone mineral concentration, sports skills, body composition and good psychology.

We should know that children and adults are different psychologically and physically, so we should design participatory and interesting activities.

For overweight teenagers, we must follow the principle of step by step when exercising, and we must not rush headlong into it and gradually increase the amount of exercise.

You can choose outdoor cycling, mountaineering, swimming, basketball, badminton, football and other sports.

You are a role model for children. When you ask your children to exercise, you should take part in it yourself.

Reduce the time of watching TV and playing computer, and don't give up exercise because of nervous study. Moderate exercise is good for your study.

Don't use supplements to increase children's physique and resistance. The best way is moderate exercise and reasonable diet.

Stay away from sweets, carbonated drinks, cold drinks and sweet drinks. Fried food and fast food.

Remember, children need time to learn a new skill and form it. Don't fight, but encourage.

Always remember that no matter how old or strong a child is, you can't impose the training guidance and concepts of adults on the teenagers who participate in the training. Coaches, including parents and teachers, must not neglect the cultivation of children's interest in sports. When children's intrinsic motivation and hobbies drive them to participate, it is entirely possible to adhere to various forms of sports plans for a long time.

⑥ The content of physique class

The basic content of physics class:

(1) Basic posture exercises

People's basic posture refers to: sitting, standing, walking and lying down. When these basic postures are presented to people, they will give people a feeling, such as dignified, straight and elegant figure, and give people a pleasing aesthetic feeling (including all daily activities).

Because a person's posture has strong plasticity, it can also have certain stability. Through certain training, many bad postures can be changed, such as sloping shoulders, hugging the chest, rambling, walking with knees bent, procrastinating and so on.

(2) Basic quality training

Physical basic quality exercise is one of the important contents of physical exercise, and there are two forms in exercise: single exercise and double cooperative exercise. Through a lot of practice, you can train the shoulders, chest, waist, abdomen, legs and other parts of the human body, and improve the support ability and flexibility of the human body.

It lays a good foundation for shaping a good human body shape and improving the control over the body. There are many exercises of basic physical skills, and we should follow the principles from easy to difficult and from simple to complex. At the same time, we should also pay attention to the tolerance of ourselves and our partners, and we should not overload ourselves to avoid injury accidents.

(3) Basic shape control exercises

Basic body control exercise is a special exercise for systematic training of practitioners' body, and it is an important content to improve and improve their body control ability. It is to further change the original state of body shape, gradually form a correct standing posture, sitting posture and walking posture, and improve the flexibility of body movements through a large number of movements such as unarmed, hand holding and double posture training.

This part of the exercise is relatively simple and requires strict personal movements, so the training must be strict and persistent.

(6) Young students' sports extended reading:

The role of physical exercise:

1, neurological function

Physical exercise is an external environment of the body. This * * * has the characteristics of continuity, coordination, speed and strength, which makes the body in motion. In this state, the central nervous system will mobilize all organs and systems at any time to coordinate and cooperate with the work of the body. Regular physical exercise can improve nerve activity accordingly.

2. Cardiovascular function

Physical training is mainly completed by the sports system, that is, the movement of bones and muscles. The exercise system consumes a lot of oxygen and nutrients (and discharges a lot of waste) when it works. At the same time, it constantly supplements and supplies a lot of fresh oxygen and nutrients, and at the same time discharges a lot of waste.

This arduous task can only be accomplished by the closed pipeline system in the body-cardiovascular (circulatory) system.

3, correct the body

In the growth and development stage, the body shape has not been properly valued and trained by scientific methods, which leads to unsatisfactory reminders, such as hunchback, X-leg, O-leg and splayed foot. Because these postures are developed from childhood, it is difficult to correct them. Therefore, it is necessary to introduce scientific and strict specialized physical training to educate and practice students, and even form dynamic stereotypes.

⑦ What is the purpose of college students' physique class?

We came to physical education class ... to do some aerobics and learn some basic dance moves such as splits. We got an examination of butterfly lovers's dance this time ... it's so soft ~ ~ ~

(8) Offering fitness courses.

Because each school has different ability to run a school, and physics class needs special classrooms and equipment (such as stereos and mats), the current situation of offering physics classes in each school is not the same. Some schools have poor teaching venues, no unified and standardized teaching materials and lack of professional teachers, so the teaching effect is not good. Some schools often become a mere formality, which can't achieve the teaching purpose of physics classes, and some schools don't even have the conditions to offer physics classes.

At present, there is no unified content of school physical education in China, which has obviously lagged behind other sports. It is an urgent task to compile a bodybuilding textbook with rich content and suitable for students. The purpose is to improve students' understanding and interest in aerobics class, and to improve students' artistic accomplishment through aerobics teaching. Therefore, fitness textbooks can make use of their rich teaching contents (basic training, China dance, China folk or national dance, ballet, fitness aerobics, competitive aerobics, ballroom dancing, hip-hop, Latin dance, boxing, yoga and other forms) and adopt various means (imitation, individual creation, collective arrangement, performance competition and so on). ), it can better satisfy the students' love of beauty. Aerobics teaching is a work of great educational significance. Through "hands-on" in fitness classes, many disadvantages and weaknesses of students, especially the character of the only child, can be suppressed. While shaping bodybuilding, we should improve flexibility, coordination, sensitivity and sense of rhythm, strengthen students' ability of communication, exchange and coordination with others, and comprehensively improve students' comprehensive potential quality. At the same time, students have enhanced their awareness of self-fitness from the subjective consciousness and mastered some scientific knowledge. Offering physical education meets the needs of social development, the integration of school physical education and lifelong physical education, and the integration of school physical education with international physical education. The development of middle school physique class will be valued, popularized and improved.

Pet-name ruby young boys how to correct the figure?

Body shape can't be corrected, but sitting posture can be corrected. It's good to exercise in the army for a few years. I love the troublesome team and sincerely answer your questions. If you are satisfied, please accept it.

Attending how to stimulate students' interest in physical education class.

Dance is a comprehensive art, covering a very wide range. The teaching of children's physique class is the dance teaching in the enlightenment period, which plays a very important basic role in the whole dance teaching. Through scientific and coordinated physical training, students can improve the coordination and flexibility of all parts of the body, promote children's bone development, enhance children's understanding of beauty and improve their physical fitness. Learning dance can mobilize students' psychology such as action, expression, posture and emotional inner experience, and provide students with aesthetic appreciation and aesthetic creation space.

1 How to realize effective teaching

In traditional physical education teaching, there is often a strong adult atmosphere. Students are passive learners and simply impart skills, and they are not interested in physical education class. Some students even hate going to physical education class. If teachers want students to like dancing and physical education class, they should first like you as a PE teacher. If you want students to like you, you should love them, have a childlike innocence, be good at listening to their voices, make friends with them, arouse their curiosity with interesting language and body movements, and attract them to the wonderful dance world. According to the characteristics of junior students, teachers should start with mobilizing students' visual and auditory senses, stimulate students' interest in dance imagination, use dynamic and lively music to arouse students' interest in dance, improve students' ability of dance imitation, thus stimulating students' interest in dance learning and improving the effectiveness of dance teaching. In order to stimulate students' interest and complete the teaching task, interesting teaching is a very effective method in the teaching process.

2 the role of interest teaching in physical education teaching

2. 1 What is interesting teaching?

Interest teaching is to stimulate students' interest, transform the basic movements of dance and the emotions of works, and make students become active participants through gamification, life and plot teaching. Teachers should fully mobilize students' visual senses, make students form a preliminary good impression on dance through observation, make use of the advantages of multimedia teaching, let students listen to all kinds of voices from nature, let students expand their imagination in all kinds of * * *, and let students feel the same feeling of "playing" in learning dance in a relaxed environment suitable for their age characteristics and life experiences, and unconsciously actively and happily devote themselves to learning.

2.2 Interest in teaching the choice of music

Teachers can fully stimulate students' interest in dance through audio-visual combination. Junior students are more active, so they choose dynamic and lively music as inspiration, which is closer to children and can better express their inner emotional changes. In the selection of teaching content in children dance, we should consider the natural law of children's physical development, and choose some music with clear rhythm, powerful movements and catchy lyrics to practice, so as to show their lively and lovely personality. At the same time, because children are in the physiological development period, their bones are soft, easy to deform, their muscles are slender, their elasticity is small, their contractility is poor, and they are prone to fatigue. These characteristics determine the poor balance and control of children's movements. Therefore, in the selection of teaching content in children dance, we should consider the natural laws of children's physical development, and strive to be stretched, short and powerful, and have a cheerful rhythm, thus showing their lively and lovely personality.

2.3 Understand the dance background

In dance teaching, teachers should first combine the dance content to help students understand the costumes, living habits and folk customs of different ethnic dances, enhance their perceptual knowledge, and lay a foundation for further learning dance. Teachers can collect pictures of different national costumes, classify them, make video materials and match them with corresponding tracks for students to enjoy. We can also design some customized games, so that students can experience the fun of the activity itself in the process of playing. Through the transformation of games, students can become active participants, transfer their enthusiasm for games to dance learning, and improve their interest in dance classes.

2.4 Role-playing in Dance

After students have a certain understanding of the background of dance, they should have a full perception of the music of dance. Teachers should let students learn dance on the basis of being familiar with music, so that students will become active. Role-playing can make students feel high, enter the role faster and experience the fun and beauty of music. Game role-playing makes students really like dance, and it will be much easier for teachers to teach dance. Therefore, it is very necessary to let students feel the music and stimulate their enthusiasm for learning dance through role-playing.

2.5 the sublimation of dance knowledge

When children are interested in dancing and have a strong desire to express themselves, we should guide them to rise from perceptual basis to rational understanding and turn their desire to express themselves into a sense of responsibility. Let them know: if you want to dance well, you must practice basic skills, have the spirit of suffering, and be as brave and strong as your uncle. At the same time, in the selection of teaching materials, we should use fresh, childlike and expressive movements and dance fragments to overcome the single and boring training methods and avoid the same, similar and similar arrangements. It is necessary to urge students to seek knowledge and difficulties in dance, so as to lay a good foundation for the next stage of "consciously suffering" training.

3 the importance of teacher demonstration

Teacher's demonstration is very important in dance teaching. Generally, before dance teaching, teachers can show their children their own comprehensive demonstrations. Under the visual impact, they became interested in dance, unconsciously moved by the teacher, and had emotional repercussions and collisions, which stimulated their desire to learn dance. On the other hand, students can appreciate the finished dance works, watch more and imitate more. Under the subtle influence of the environment, students love dance, thus generating strong interest. When learning movements step by step, teachers should pay attention to simplifying movements step by step, so that students can master the essentials of movements.

4 teachers' language guidance

The teacher's vivid, concise and childlike language is the basis of a successful dance teaching class. The language used by teachers to explain actions should be suitable for students' age characteristics and stimulate students' interest. Instead of using rigid hands and feet to complete exercises, it should be suitable for students' interest trends. Lively children's songs or stories can arouse children's interest, so that children will not feel tired and difficult to learn dance. They should be good at using vivid language to help students master the essentials of action. Good at mobilizing students' senses through various means and stimulating students' desire to learn dance.

Dance teaching is a comprehensive education for students, and students' body, mind and emotion will be nourished, cultivated and exercised in dance. Learning dance can improve students' self-confidence, cultivate noble temperament and enthusiastic spirit, make students know how to love life and cultivate their optimistic and enterprising spirit imperceptibly. Therefore, the core role of teachers in dance teaching can not be ignored. Good teaching methods can firmly grasp children's attention, stimulate children's thirst for knowledge, and stimulate their enthusiasm for learning, so as to achieve the ideal teaching effect, and can also quickly realize the effective classroom teaching of primary school physics.
