(2) Why did you choose these test items?
According to China's national conditions, under the premise of fully considering the scientificity, comprehensiveness and operability of the test content, the test items selected in the Standard for Students' Physical Health highlight the content elements of developing and improving physical health quality, aiming at promoting the improvement, development and improvement of body composition, cardiovascular system function, muscle strength, endurance and flexibility that have a direct impact on students' health.
(3) Why do you want to set up selective testing items?
The establishment of selective testing project aims to guide students to exercise in an all-round way; Lighten the burden of testing for students, teachers and schools: emphasize the process of comprehensive physical exercise; Realize the separation of teaching content and examination items, and overcome the disadvantages of exam-oriented education.
Ensure the normal teaching activities of physical education and health class.
The examination items are randomly determined by the local (city) level education administrative departments before the examination.
(4) What is the significance of standard weight to height?
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. It is an important index to evaluate the level of human morphological development, nutritional status and body symmetry. Whether a person's body shape is fat, strong or thin is aimed at whether the proportion of height and weight is moderate. It is of great significance to detect the standard weight of height regularly for mastering whether your weight is appropriate, whether you need to adjust your diet, and evaluating the size of exercise and the changes of physiological functions.
The standard weight measurement method for height is simple and easy, which can indirectly reflect the body composition of human body. If your height standard weight is less than or greater than the height standard weight of the same age, it means that your figure 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.
(5) Is the step test index high or low?
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; Or conversely, regular aerobic exercise in Dallas audience can improve the functional level of your cardiovascular system, which is manifested in the decrease of pulse rate when you finish the quantitative load work of step test; After the experiment, the time taken for the number of pulses to return to the quiet state was shortened; Step test index increased.
(6) Why should the endurance running test be conducted?
Endurance running is one of the easiest methods to evaluate the function level of cardiovascular system at home and abroad. People with high cardiovascular function spend relatively less time running the same distance. Therefore, such as
If you have a strong cardiovascular system, you can do well in the endurance test. If you use 100% of "strength", you still can't achieve the desired effect, which shows that your cardiovascular system is not functioning well and there is still considerable room for development. You can improve and improve through gradual aerobic endurance exercise, scientific diet control and weight loss.
(7) Why should we use vital capacity and body mass index for evaluation?
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. Because the size of vital capacity is closely related to factors such as weight, height and chest circumference. Therefore, in order to reflect the unsynchronized factors of students' physical development in the evaluation of lung function, the vital capacity body mass index is selected.
(8) What is the significance of the 50-meter running test?
Although the structure of the 50-meter run is simple, it can reflect the flexibility of your nervous process, the coordination of your body, the flexibility of your joints and muscles, and the strength and endurance of your muscles. We can't expect a person with inflexible body, weak muscles, poor coordination and flexibility to get good results in the 50-meter race test. Therefore, the test results of 50-meter running can partly reflect your comprehensive physical fitness, which is also the basic physical fitness you must have to engage in sports activities and learn sports skills. Middle school is a good opportunity to develop speed quality. You should seize this opportunity to promote the development of speed quality and lay a good foundation for lifelong sports.
