1.Preface
Health is the cornerstone of people's all-round development and happiness.It is also an important symbol of national prosperity and social progress.Without people's health, there will be no well-off society in an all-round way.As the connecting point between universities and society, the physical health of university students is particularly important, especially the physical health of students with physical defects or obesity, which is one of the major problems that the physical education teachers in colleges and universities need to solve.Due to physical limitations, students from vulnerable groups are unable to participate in medium and high intensity sports, so they are limited in the choice of sports activities.As a non-competitive sport, fitness yoga is not limited by venue and time, and can meet the needs of different categories of people, Yoga postural stretching can stretch stiff muscles, improve the flexibility of the body ; Yoga meditation can relieve anxiety, benefit physical development, pleasure and improve happiness [1] ; It is safe and simple, and plays an important role in improving the physical and mental health of students in vulnerable groups and improving the quality of life.

Concept definition 2.1Physically vulnerable groups
Physically vulnerable groups refers to the group whose body is in a disadvantageous position in terms of physical development, especially those who are relatively disadvantaged in learning and living based on physical strength. [2]The definition of physically vulnerable groups includes one sufficient condition and two basic criteria: sufficient condition is people who suffer from diseases or physical disabilities that are not suitable for taking part in strenuous physical exercise (including heavy physical work); One of the basic criteria is the population whose test results have not reached the passing grade of the National Physique Measurement Standard; The second basic criterion is the body mass index (BIM) test results in the following range: BIM < 20(lean body development), or BIM≥26.5 (obese body development).Groups that meet the above sufficient conditions or one of the two basic criteria can basically be identified as physically vulnerable groups.

Health promotion
The term "health promotion" was first proposed by the World Health Organization at the first International Conference on Health Promotion held in Ottawa, Canada, on November 21, 1986.It refers to the use of administrative or organizational means to widely coordinate the relevant sectors of society as well as communities, families and individuals.A social behavior and social strategy that enables them to fulfill their respective responsibilities for health and jointly safeguard and promote health. [3]Compared with health education, the meaning of health promotion is broader, it includes health education and can promote behavior, environmental change organization, policy, economic support and other strategies.

Fitness yoga

[4]Fitness yoga is not a school or branch of yoga, but basically covers the whole content of yoga, including body adjustment, pranayama, and heart adjustment.Fitness yoga is the product of localization and Chinese yoga.According to the research and development of China's national conditions and public fitness needs, around the basic connotation of fitness yoga, through various efforts, the basic position 108 is determined, and according to the difficulty of completing the position, it is divided into 5 levels from low to high, the first 4 levels of 24 individual positions, and the fifth level of 12 elective positions.

Problems existing in students of physically disadvantaged groups
In recent years, the physical health status of Chinese college students has been improved to some extent, and the decline trend of speed, endurance and strength quality has gradually eased, but the detection rate of overweight and obesity continues to increase, and the detection rate of poor eyesight remains high.This not only becomes the invisible killer of the healthy development of college students, but also brings great pressure to their study and employment.In addition, college students with some chronic diseases or physical disabilities have more difficulties and obstacles in daily life and social communication than students with healthy bodies.There are differences in appearance, physiology, psychology and social communication among college students of the physically disadvantaged groups.

The physical quality of students in physically vulnerable groups is lower than that of students in non-physically vulnerable groups
Due to the physical characteristics, dismemberment, sequelae of sports injury, congenital or acquired physical diseases and mental diseases, students of physically vulnerable groups have poor physical quality and sports ability, and are at a significant disadvantage in engaging in physical study and life.Because of their special appearance, some of them are physically disabled, some are too obese, and some are too thin, which makes them unable to participate in normal sports activities like normal students.At the same time, due to the relatively low level of sports, they are timid, inferior and lack of self-confidence in sports activities, which also affects their enthusiasm to participate in sports activities to a certain extent.On the other hand, there are relatively few sports items suitable for students of the physically disadvantaged groups, and even fewer items of interest.
As a result, students of the physically disadvantaged groups lack their own interest in physical exercise, and thus participate in physical exercise less frequently and less frequently, and it is difficult to achieve the expected results in exercise.In the long run, it will enter a vicious cycle, and health will be worse and worse.

Students of physically vulnerable groups have a low level of mental health

The social adaptability of students from physically disadvantaged groups is worse than that of students from non-physically disadvantaged groups
The main place for college students to adapt to society is the school.College students' campus life includes not only study, but also a variety of student associations and sports clubs.Students can choose associations and clubs according to their own interests.However, the activities and content Settings of these associations and clubs are mostly for students with normal physical quality, and there are not many opportunities for students with weak physical conditions to choose.Therefore, compared with students from non-physically disadvantaged groups, students from physically disadvantaged groups are less likely to participate in various activities, especially sports activities, and lack platforms and media to communicate with other students who have common interests and hobbies.As a result, they are relatively low in cooperation, communication, competition consciousness and concern for the collective, which affects the development of their social adaptability.
