According to the students' total academic year scores, the scores are: above 90.0 for excellent, 80.0 ~ 89.9 for good, 60.0 ~ 79.9 for passing, and below 59.9 for failing. 800 meters belongs to track and field middle and long distance running, which requires the combination of speed and endurance. Endurance and speed cannot be improved in a short time.
100 -3' 18 "
90 minutes -3 feet 28 inches
80 minutes -3 feet 42 inches
70 minutes -4 feet 07 inches
60 minutes -4 feet 32 inches
However, due to the different test scoring standards in different regions, the following statements are for reference only:
Extended data
Endurance running skills
Control the breathing rhythm of running 800 meters.
Control your breathing, two-step breathing, two-step breathing, or three-step breathing, depending on your situation, keep a good rhythm and don't screw it up. It's best not to open your mouth and breathe. If you are really tired, you can take a small breath. Don't gasp, hurt your stomach, hurt your throat and affect your running.
Step frequency and step size
It is extremely important to increase the step length and step frequency to improve the performance of middle and long distance running. But step frequency and step size are a pair of contradictions. When the step size increases, the step frequency is relatively slow, and when the step frequency increases, the step size may become relatively small.
Therefore, it is difficult to increase step size and step frequency at the same time. Usually, you can only keep the step size to improve the step frequency, or keep the step frequency to improve the step size to achieve the purpose of improving your grades.
Under normal circumstances, for men with a height of 1.75M, the stride should be 1.8M-2m, and for women with a height of 1.6M, the stride can be 1.5M- 1.7M (according to the height ratio, the lower limit for men is/kloc. Pay attention to calculating the average step length of 100M during training, and convert it to at least reach the lower limit of the step length.
If you happen to have short legs and short body, then you need to increase the stride frequency appropriately, usually 3.5 times per second.
