3. Primary school students' sports health knowledge

Pupils grow and develop rapidly, their bodies are immature, and their bones, muscles, internal organs and other organs are fragile, so we must not neglect maintenance. The content of physical education class in primary schools must be conducive to promoting the all-round development of students' bodies and effectively exercising and strengthening their physique.

First, choose the right venue.

At present, the general school sports venues are mostly cement, such as basketball courts and volleyball courts. In fact, the playground paved with cement asphalt is hard and elastic. Jumping in this site run for a long time is not only easy to cause trauma, but also causes chronic damage to the human body. Therefore, qualified schools should try to set up plastic venues. This kind of venue can protect students from injury, and schools without conditions try to keep soil venues and battlefields.

Second, ensure the safety of equipment.

The choice of equipment is very important for the safety of students. Schools should strive to complete equipment in accordance with the requirements of the new curriculum standards. If there is no supporting equipment for the time being due to conditions, teachers and students can be mobilized to make their own equipment, but health and safety factors must be considered. It is necessary to ensure that unqualified equipment is not used, and bad equipment cannot be used.

Third, matters needing attention in class

1. Reasonable selection of exercise load. The characteristics of physical education itself determine that physical exercise is the main feature, outdoor is the main place, and it is dynamic, which increases the difficulty of organizing teaching. If students use instruments improperly or have too much physiological load, they are prone to injury accidents.

2. Strengthen physical education class's safety awareness. Physical education class needs students' bodies to participate in activities directly, which is really unsafe and potentially dangerous. However, as long as we attach importance to maintenance education, organize classes well, conduct teaching correctly and scientifically, and strengthen maintenance measures, injury accidents can be avoided.

3. Safety begins with the teacher. As a qualified physical education teacher, the consciousness of saving should permeate every link of preparing lessons, attending classes and summarizing after class. When preparing lessons, we should fully consider all kinds of unsafe factors and eliminate them one by one through our own efforts. We should not only write lesson plans well, but also prepare teaching materials, students and venue equipment, ponder the technical essentials, action structure, key and difficult points, protection and help of teaching materials, and fully understand the students' situation, such as physical condition, hobbies, discipline habits, sports ability and so on.

4. Teaching should be rigorous. In the teaching process, teachers should impart correct knowledge, sensitive skills and skillful skills to students, adopt scientific teaching methods, so that students can understand and master the essentials of movements, make clear the technical specifications and conduct accurate drills. Teachers must also personally lead or guide students to do adequate preparatory activities and necessary special exercises.

5. Clothing can't be ignored. Teachers must have strict requirements on physical education class's dress, so that students can gradually develop good habits. For example, don't wear leather shoes, sandals and plastic shoes; Do not carry sharp tools, such as keys and knives.

4. Urgent exercise health tips 10

It is not advisable to take a bath immediately after exercise.

Usually, many people like to take a hot bath after exercise, thinking that it can decontaminate and restore fatigue. In fact, the body has not returned to normal after exercise, so it is not appropriate to take a bath immediately, especially a hot bath.

According to the research of sports medicine experts, when people exercise, the blood flowing to muscles increases and the heart rate accelerates. When exercise stops, blood flow and heart rate will be relieved, but it will last for a long time. If you take a bath immediately, it will increase the blood flow to your skin and muscles. This makes the remaining blood insufficient to supply other weights.

Important organs such as the heart and brain can cause heart disease.

Some people take a hot bath after exercise, and then often feel dizzy and weak, which is the reason mentioned above. Especially the elderly or obese, you can't take a hot bath immediately after exercise.

Lack of exercise leads to modern rich diseases.

Everyone can't live without exercise, from toddlers to various sports, all for survival and health. Only when human beings have strong physique and good psychological quality can they adapt to the needs of society. In ancient times, human beings struggled with wild animals with strong bodies, caught food and adapted to the harsh natural environment. In modern society, the living conditions have been greatly improved. The food we eat is rich in nutrition, and the living conditions are warm in winter and cool in summer. Instead of walking by car, heavy manual labor is replaced by machines. Some people say that the development of material civilization is the root of hyperlipidemia, hyperglycemia, hypertension and cardiovascular and cerebrovascular diseases. Indeed, these diseases are closely related to environmental pollution, food pollution, air pollution and water pollution. In addition, there is another important factor that leads to the high incidence of modern "rich diseases", that is, modern people lack the necessary fitness exercise.

Another thing to note is that the exercise time should not be too short, let alone too long. The time is too short and the heat consumption is not enough. Of course, moving is better than not moving, even if it's just moving your arms and relaxing your muscles. Too long exercise time will affect the next day's work or study. In short, regular exercise is better, not excessive. It should be perseverance and long-term success.

Flow. It has been a truth since ancient times and will always be useful.

You should eat alkaline food after exercise.

After strenuous exercise, people will feel sore, tired and thirsty in their waist, legs or whole body muscles. At this time, some people will end up drinking coke, some people will munch on chocolate, and some people will eat chicken and fish. They don't know that the more they eat like this, the more serious their muscle aches and fatigue are. The reason is that the acid-base balance in the body not only can't maintain the body fluid normally, but aggravate the fatigue symptoms. Usually our food can be divided into acidic food and alkaline food. Judging the acidity and alkalinity of food is not based on human taste, nor on the chemical properties of food in water, but on the acidity and alkalinity of the final metabolites produced after food enters the human body. Protein, fat and sugar foods, which contain nonmetallic elements such as nitrogen and phosphorus, are acidic foods; Vegetables, fruits, bean products, etc. It contains many metal elements such as sodium, potassium, calcium and magnesium, and belongs to alkaline food. These foods are metabolized in the body to produce alkaline substances, which can prevent the blood from becoming acidic. Although fruit is sour, it is an alkaline food; Fish, meat, eggs, sugar, etc. are not sour, but they are acidic foods.

Normal body fluids are weakly alkaline. After physical exercise, people will feel sore muscles and joints and mental fatigue. The main reason is that a large number of sugar, fat and protein in the body are decomposed, and acid substances such as lactic acid and phosphoric acid are produced in the process of decomposition. These acidic substances make people feel sore muscles and joints, and mental fatigue occurs in human tissues and organs. At this time, you should eat more alkaline foods such as milk, bean products, vegetables and fruits to neutralize the acidic components in the body and relieve fatigue.

What diseases can regular exercise prevent?

Just because you exercise regularly doesn't mean you can live a long and healthy life. At present, scientific research can only confirm the following facts: a healthy and balanced diet, normal weight and moderate exercise can prevent the occurrence of13 tumor. In addition, participating in sports activities can also prevent the occurrence of 60% type II diabetes, reduce the incidence, hospitalization rate, disability rate and mortality rate of non-communicable diseases, help patients with hypertension and diabetes control their blood pressure and blood sugar, and prevent osteoporosis. It is beneficial to reduce the ratio of total cholesterol to high-density lipoprotein cholesterol, adjust mental and psychological balance, reduce stress, enhance self-confidence, and relieve depression and anxiety.

Don't forget to "cool down" after exercise

"Cooling down" after exercise is as important as "preheating" before fitness. After exercise, the human body needs to gradually return to a relatively quiet state. This process is not only a means to cope with physical and mental tension and relaxation in sports, but also an important link between sports and daily life and work. From a psychological point of view, if you want to relax, you should first relax in your mind. A good mood can promote people's behavior, while a negative mood may also make the original interesting things dull. From the physiological point of view, only when you are in a good mood can you relieve the tense state of physical function formed during exercise in time, so that the respiratory system, cardiovascular system, muscles, joints and ligaments can relax and rest after exercise; The circulatory system restores normal physiological activities in time, transports nutrients and supplements oxygen debts, thus eliminating fatigue; Transfer the corresponding excitation center of cerebral cortex, so that excitation and inhibition can adjust each other, thus achieving the purpose of strengthening the body, strengthening the brain and improving intelligence.

5. The sports meeting will submit 10 articles, each of which is about 30 spans.

One: Autumn in October, sweet-scented osmanthus fragrance, we ushered in the annual school sports meeting.

Colorful flags are flying on the playground, and there are no clouds in Wan Li and Wan Li. First, the drum team blows into the field, and then the athletes of each class walk around the field. The athletes in each class shouted their own slogans and cheered for themselves. The headmaster gave a congratulatory message to the sports meeting, and the director announced the opening of the sports meeting-"I wish all athletes good results in this sports meeting."

Then the cheerleaders perform. Cheerleaders dressed in red are standing on the green lawn, just like small flowers fluttering in the breeze.

The first events are shot put, high jump and 50-meter race. As soon as the gunshots rang, the athletes ran like arrows, and there was a boiling outside the venue, shouting "Come on! Come on! " Wangye of our class pushed forward and finally won the first place in this project.

The women's 400 meters is about to start, and the final preparations are being made for the sports meeting. With the starting gun, the athletes have left the starting line.

Tong Xin, the general of our class, ranks third. The students were very anxious and shouted desperately: "Come on, Tong Xin!" Come on, Tong Xin! ..... "It seems that our cheers infected her. In the end, she entered the final with the first place in the small group, nearly 10 second faster than the second place. The students in my class cheered with joy.

What excites us most is the women's 4 * 100 meter relay race. Four generals in our class: Lu Yi-women's 100 meter champion; Tong Xin-women's 400m champion, 200m runner-up; Xin Li-women's high jump champion, 200-meter champion; Wangye-Women's 50m champion, runner-up in long jump.

Such a strong combination, the champion must be theirs. In the1500m race, when the first runner has already crossed the finish line, the last runner, Yang Shuheng of our class, still needs nearly two laps to finish.

Although his performance in the game is not ideal, his willpower is very rare. He finished the whole race, but he was not cheered. Instead, he was laughed at, laughed at his humiliation, laughed at his lack of strength to participate in the race, and laughed at the gap between him and others ... I think it's ridiculous to laugh at Yang Shuheng! They don't have the guts to run 1500. How can they criticize others? Exercise is about participation, so why pay too much attention to results? The process is the most important and wonderful, isn't it? Yang Shuheng, who gave up halfway in the cotton team, is so tall.

This school sports meeting brought us a lot of joy, but it also brought us a lot of inspiration. Maybe your mind is uneasy. Our minds are already boiling with blood. In the past, you left deep footprints on the long runway, and your sweaty feet could not be wiped off. You don't care about your fatigue, sweat and tears for the branches, because you have a firm belief in your heart. 2. Give the referee teacher A to the referee teacher. Perhaps, you missed the loud voice, but it was your eyes that cheered! Perhaps, the hot Levin has never pitied you, but you are a tall figure under the scorching sun. Perhaps, praise and expectation always pass you by, but real gratitude flows in everyone's heart.

Silent words turned into voices: teacher, the honor is yours. -B To the judges in Congress, the same education, the same exposure, no warm cheers, no fierce applause.

But you still use sophisticated instruments and meticulous patience to record the glory of sports. Dear teachers, we are proud of you and have worked hard! -c to the referee. Perhaps, you missed the loud voice, but it was your eyes that cheered! Perhaps, the hot Levin has never pitied you, but you are a tall figure under the scorching sun.

Perhaps, praise and expectation always pass you by, but real gratitude flows in everyone's heart. Silent words turned into voices: teacher, the honor is yours.

-d Give applause to the judges on the playground of this competition. I don't know how much the judges have paid in every achievement of the athletes. Two things can't stop enthusiasm and heat wave collapse. They have created us, are creating us, have created us, and will create us in the future ... Ah, thank you, our judges, we will win the impact with our own actions and get a little freedom of conscience. Come on, athletes, cheerleaders. E For the referee, a good beginning is half the battle, but you, the referee, are the key to our destination.

Your fairness is the foot we use to walk; Your patience is a step for us; Your seriousness is the road we have traveled. Balanced justice shows your integrity and selflessness.

Please let me say it again: Mr. referee, you have worked hard! -You used sophisticated instruments and meticulous patience to record the brilliance of the athletes.

Dear teacher, I am proud of you. I also work hard in ............................................................................................................................................................ We will write our own life absolutely seriously, maybe not better than others, but definitely better than the first time. Perhaps, life can't be as beautiful as you think, the road of life can't be smooth sailing, and people's mood won't be as calm as water forever.

In life, there are successes and failures. Therefore, we have to let go of life, maybe the distance is very slim, maybe we will be stabbed by the "thorns knocked over in life", but we still have no regrets.

Flying, even at dusk, will.

6. Pupils leave about thirty crosses.

1. Dear teacher:

Thank you for your education, meticulous care and help to your child this semester, which has improved his academic performance by leaps and bounds.

As a parent, I will also urge my child to study hard and hope that his grades will get better and better.

Thank you again for your hard work!

2. After reading the report card of * * *, it can be said that it is not ideal. As parents, we have certain responsibilities. When children go to school, they should learn cultural knowledge well, that is, develop morally, intellectually and physically in an all-round way, that is, give full play to their talents to learn professional knowledge. I hope that teachers, students and parents will help educate him, and that our son will respect teachers, unite with classmates, overcome shortcomings and learn knowledge well.

3. The nine-story platform starts from the foundation, and the journey of a thousand miles begins with the first step, climbing the top of reason. There is no one-step shortcut, only struggle, learn a knowledge well, not just understanding and learning, but also learning and doing. Strive to become an applied talent beneficial to society.

4. Teaching: Teaching and learning should be targeted. I hope to implement the contents of various tutorials for students' future competitive employment, and strengthen that every student can learn one or two good skills and real kung fu during school. As long as it is conducive to students' study, parents don't want the school to "reduce the burden".
