First, the significance of the "Students' Physical Health Standards" test

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, improve the level of physical education class, enhance students' physical fitness, improve their health level, and cultivate students into high-quality talents with all-round development in morality, intelligence, physique and aesthetics.

Through the test of "Students' Physical Health Standard", students can clearly understand their physical health status, and can also monitor the change degree of their physical health. All these are helpful for students to set their own exercise goals, choose exercise strategies and make practical exercise plans.

Two, "students' physical health standards" test items and evaluation requirements

According to the requirements of "Students' Physical Fitness and Health Standard", college students need to complete six tests, namely, height, weight, vital capacity, step test, 50-meter running or standing long jump (choose one), grip strength or sit-ups (girls) or sitting forward (choose one).

Five indicators are evaluated in the evaluation: height standard weight, vital capacity body mass index, step index, 50-meter running or standing long jump (choose one), grip body mass index or sit-ups (girls) or sitting forward (choose one).

The score after evaluation is 100, and the weighted score of each evaluation score is: height standard weight15; Step index 20 points; Vital capacity and body mass index 15; 30 points for 50-meter running or standing long jump; Grip strength, body mass index, sit-ups (girls) or forward flexion of sitting position by 20 points.

Third, the significance of each test index

(1) height and standard weight

Height standard weight refers to the ratio of height to weight, which should be within the normal range. It reflects the girth, width, thickness and density of human body through a certain proportional relationship between 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 the measured height standard weight deviates from the range of height standard weight of the same age, it means that the symmetry of the body is not good, and it is necessary to increase muscle tissue or reduce excess fat in the body by adjusting the diet structure or actively participating in exercise.

Body composition refers to the proportion of fat and non-fat components in the whole human body, which can accurately evaluate the degree of fatness and thinness of the human body, usually expressed as a percentage of body fat, that is, the proportion of body fat.

(2) Step test index

Step test index is an important index reflecting the function of human cardiovascular system. The greater the step test index, the higher the functional level of cardiovascular system. Regular participation in aerobic metabolic exercise can improve the functional level of cardiovascular system, which is manifested by the decrease of pulse beating times when quantitative load of step test is completed.

After the test, the time required for the pulse number to return to a quiet state 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 does not accumulate in the body, 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.
