College students need to pass the physical examination of 4 minutes and 34 seconds 800 meters in freshman and sophomore, and 4 minutes and 32 seconds in junior and senior.
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.
Precautions for running:
As for running time, I personally like evening exercise, and some people like morning exercise. In fact, for most people with normal constitution, as long as they avoid half an hour before meals, one hour after meals and two hours before going to bed, they can do physical exercise at other times. If you have formed the habit of doing morning exercises, persistence will certainly benefit you a lot. There is no need to change it to evening exercise.
For friends who don't usually exercise and plan to exercise at this time, the best running time is not at night, nor in the morning, but immediately. Only when you are exercising, stick to it and think about things in the morning and evening, because running is more about whether you have time at this time than environmental time. Running is more important than not running.
Many people often fail in running because they think too much about when is the best time to run. This is because they choke on food. My idea of running is to find a suitable time and place according to my own environment and working hours.
Generally speaking, you have to run at least three times a week to gradually improve your cardiopulmonary function. "I want to run every day", if you think so, you'd better control it within 5 times a week, because beyond this range, you may unconsciously accumulate fatigue of bones and joints and psychological pressure.
