Eating some chocolate (cocoa butter, not cocoa butter) before the exam can help you get excited and provide calories. After the exam, you can drink glucose, which helps to restore your physical strength. Here is a special reminder: never drink white water after running, because it will dilute the blood and lead to dizziness or even fainting (this has not been verified, so our coach said so at that time)
The following is the answer I just gave to others, so I copied and pasted it directly. I hope it helps you.
Running mode: the palm is half clenched (fingers bent, palms spread out) and cannot be spread out completely. If the palm of your hand is spread out completely, blood will accumulate at your fingertips and it will not circulate (you can try it yourself if you don't believe me). Breathing is mainly 1 inhalation 2 vomiting, with long inhalation and short exhalation, so as to achieve breathing regularity. When moving in a straight line at a uniform speed, it should be noted that the left and right arms need to be consistent when swinging. When entering the corner, the body leans to the left (generally running in track and field, only turning left), the swing amplitude of the left hand decreases, and the swing amplitude of the right hand increases appropriately (note: it is the swing amplitude, not the frequency).
Tip: 1, you need to finish the first place in the first 800 meters, and look at the back of the head of the competitor in front. Don't run in the first 800 meters, because there is no reference in front of the leading runner, who can only look at the runway, and it is easy to get dizzy under the condition of insufficient blood supply to the brain. If you haven't exercised for a long time, you need to start exercising one week in advance (preferably one week in advance). If you suddenly run 1000 meters, you can't get out of bed the next day because there is a lot of lactic acid in your muscles.
This is my previous experience in track and field training. I hope it will help the landlord. It is made by hand (typing is not easy), and I hope it can be adopted.
Tomorrow is 1 1: 00 physical education exam, running 1000 meters, what to eat before running. Drink milk and eat bread. When running, keep your head down and look at the track. Breathe evenly.
Tomorrow's mid-term exam1000 m. What do you drink and eat before running? Haha, Red Bull must drink it all at once, you will feel hot. It is very useful to listen to it alone during the senior high school entrance examination.
Tomorrow is the physical education exam. I'm not a professional, so I'll just say a few things I know about how to run 1000m, what to do and what to eat before running. Adjust the breathing rhythm to match the pace, inhale through the nose and exhale through the mouth. Even if you feel uncomfortable coughing during the process, try to hold back or adjust it slightly without disturbing the rhythm. If people run beyond their physical limits, there will be a "realm", and then you will gradually not feel tired. Be sure to keep this state, drink some water properly before the exam, but not too much, try to keep moving at a constant speed, and finally do your best. It takes two or three seconds! Don't sit down, lie down or drink water immediately after running, which is bad for your heart. People who run marathons will be specially helped after running, because lying down immediately may lead to sudden death! Although not as good as a marathon, be careful. I suggest you take a walk and drink some sports drinks after you calm down. Then have a good rest. If the eardrum hurts or something, just be patient. It's normal after all. Besides, there should be a lot of training at ordinary times, and the first grade and even the fifth and sixth grades have started training! Looking back, the 30 laps of the primary school football team ... are still very memorable, and it is a combination of frog jumping and duck walking ... (complicated) Come on anyway! ? (? )?
There will be a physical examination in the mid-term exam tomorrow. /kloc-what do you need to eat at 0/000 meters? Red bull with inositol content of 50.
Is there a scientific basis for "what you eat supplements what you eat"? There is no scientific basis for "what you eat supplements what you eat".
China's traditional view of "shape complements shape" is very popular among the people. "Shape-supplementing" is to supplement the relative organs and functions of the human body with foods with similar shapes and functions. "Make up for what you eat", such as patients with weak hands and feet, eat more pig's trotters-make up for it with "foot"; There is also a "liver" to replenish the liver; Another example is deer whip and sheep whip to treat sexual dysfunction.
"Complementing shape with shape" is a simple analogy and inference, which is very far-fetched. Diversification of food and a balanced diet structure are the basis of a healthy life. After all, food is food and cannot replace medicine. Don't be superstitious about the effects of any kind of food on diseases.
From the biological point of view, there is no scientific basis for filling shapes with shapes. Food supplement is only that some nutrients or vitamins in certain foods will be absorbed by the human body.
