There are four remarkable characteristics in the physical condition of adolescents in China: serious obesity and overweight, serious decline in cardiopulmonary function and endurance quality, continuous increase in the incidence of poor eyesight and its development towards younger age, and continuous decline in the physical function and quality of college students.
1995 is the year when the nutritional status of children and adolescents in China changed: from 1995, the proportion of children and adolescents with overnutrition (overweight and obesity) began to increase, while the proportion of children with normal weight decreased.
Body mass index (BMI) is a commonly used index to measure the degree of obesity in the world. Too high and too low body mass index indicate obesity and emaciation respectively. In six national surveys on students' physical health, the relationship between children's and adolescents' physical health index and body mass index is inverted U-shaped, that is, the physical health index of emaciated children and obese children is low.
Drinking a lot in the middle of the night, studying and entertaining in bed, indulging in irregular life, leading to a decline in physical fitness; The canteen and dormitory of the teaching building constitute the university life, which leads to the decline of physical fitness; The pressure of life, fast social rhythm, tired work, little rest and little time for exercise make many young people in a sub-health state; Daily gatherings and dinners increase, and there are many big fish and meat in the diet, which leads to physical decline, and so on. What is the reason for the decline of our young people's physical fitness? 65.4% of the young people surveyed think that they have weak health awareness and less exercise times; 52.3% of the young people interviewed think that the study work is heavy and the life pressure is great; 49.9% of the young people interviewed think that there are too many forms of entertainment, which squeezes the exercise time; 49.0% of the young people interviewed think that their living habits are not good and their work and rest are irregular.
The declining physique of teenagers in China is indeed related to the lack of physical exercise, but it is definitely not just because of the lack of physical exercise. In the fiery red age, there is a saying that people exercise in the stormy waves of social practice and production practice. Pay attention to the sports here, including sports and labor. Nowadays, young people lack physical exercise, productive labor exercise and the ideology of "glorious labor".
