Students' physical health standard is an integral part of the national physical exercise standard, and it is the concrete application of the national physical exercise standard in schools. The purpose of the "Students' Physical Fitness and Health Standard" test is to implement the spirit of "school education should establish the guiding ideology of health first" put forward by the Third National Education Work Conference, to promote students to actively participate in physical exercise, to be a good physical education class, to enhance students' physical fitness and improve their health level, and to cultivate students into high-quality talents with all-round development in morality, intelligence, physique and aesthetics.
Through the test of "Students' Physical Health Standard", you can clearly understand your physical health and help you monitor the changes of your physical health. All these will help you to make your own exercise goals, choose exercise strategies and make practical exercise plans in the new year.
Importance of each test value
1, height and standard weight
Height standard weight means that the ratio of height to weight should be within the normal range. It reflects the circumference, width, thickness and density of human body through a certain proportion of height and weight. Height standard weight is an important index to evaluate the level of human morphological development, nutritional status and body symmetry. It can indirectly reflect the body composition of human body, and its measurement method is simple and easy. If your height standard value is less than or greater than the range of height standard weight of the same age, it means that your body is not symmetrical, and you need to increase muscle tissue or reduce excess fat in your body by adjusting your diet or actively participating in exercise.
Body composition refers to the proportion of fat components and non-fat components in the whole human body, which can accurately evaluate the degree of obesity in the body. It is usually expressed as a percentage of body fat, that is, the proportion of body fat.
2. Bench test index
Step test index is an important index reflecting the function of human cardiovascular system. The greater the step test index, the higher your cardiovascular system function level, and vice versa.
Regular participation in aerobic metabolic exercise can improve the functional level of cardiovascular system, which is manifested in the decrease of pulse beat when quantitative load of step test is completed, the time for pulse beat to return to quiet state after test is shortened, and the step test index is increased.
Aerobic metabolic exercise refers to the exercise that the body's oxygen demand and oxygen intake reach a dynamic balance. When doing aerobic exercise, lactic acid accumulation does not occur at rest, and the heart rate and breathing remain stable, so continuous exercise time is long, safety is high, and fat consumption is high, which is conducive to improving the function of cardiovascular system.
3. Vital capacity and body mass index
Vital capacity is an important index to evaluate the function of human respiratory system. Scientists point out that it is difficult for people with low lung capacity to share a long life with people with high lung capacity. The size of vital capacity is closely related to factors such as weight, height and chest circumference. Therefore, in order to reflect the different factors of students' physical development in the evaluation of lung function, vital capacity and body mass index were selected in the test of Students' Physical Health Standard.
Vital capacity and body mass index = vital capacity (ml)/body weight
4.50-meter run
The result of 50-meter running can comprehensively reflect the flexibility of nerve process, the coordination of body, the flexibility of joints and muscles, the strength and endurance of muscles. It can not only partially reflect the comprehensive quality of physical transport, but also be the basic physical quality that people must have in sports activities and learning sports skills.
5. Standing long jump
Standing long jump mainly measures the explosive force of lower limb muscles when jumping forward. Strength (maximum strength) is a very important physical quality in sports and daily life. The explosive power of legs is based on the strength of legs. Without strength, there is no explosive force, and there is no muscle endurance.
6. Grip strength and body mass index
Grip strength The body mass index reflects the relative strength of muscles, that is, the grip strength per kilogram of body weight. Grip strength mainly reflects the strength of human forearm and hand muscles, and it is also related to the strength of other muscle groups, and it is also a good indicator to reflect the overall strength of muscles.
Grip strength body mass index = grip strength (kg)/weight × 100
7. Sit-ups
Sit-ups test is one of the methods to evaluate muscle strength and endurance. Because it can safely test the strength and endurance of muscles, and at the same time, when doing sit-ups, the abdominal muscles are mainly doing work, and the iliac muscles are also participating in the work, so this test not only evaluates the endurance of human abdominal muscles, but also reflects the endurance of iliac muscles. Because the strength and endurance of these two muscles are closely related to some physiological functions of girls, sit-ups are separately listed as optional test items for girls.
1, sit forward
Sitting flexion test reflects the flexibility of joints and muscles. Poor flexibility means that the corresponding joints and muscles lack exercise. Long-term lack of flexible exercise will lead to degeneration, contracture and even adhesion of joints or soft tissues around joints, thus limiting the range of joint activities and inevitably causing pain when pulling. Therefore, expanding the range of joint activities will expand the painless range of human activities.
Flexibility refers to the range of motion of all joints in the body and the elasticity and stretching ability of ligaments, tendons, muscles, skin and other tissues across joints. It is an important physical component.
