Personal experience of physical exercise (I) People's personalities are various. Some are lively and cheerful, some are silent, some are bold, some are as timid as a mouse ... and I belong to the timid category. Mother said, "This kind of personality is not pleasing. It needs to change. "
During the summer vacation, my mother and I went to my grandmother's house thousands of miles away. One night, a big family was walking on the Grand Canal Square in Huai 'an City, Jiangsu Province. In the store in the square, I couldn't put it down when I saw roller skates. So, my cousin and I bought a pair. None of us can ice, and the adults said in unison, "Let's see who learns first." Cousin Chen Sixuan is naturally active. From the scars on her body, I know that she especially likes to play exciting games. Sure enough, Xuan Si will fly solo after several laps. Cousin Huang Xu, though timid, just walked around, walking around. I never dared to put on roller skates, but I became their cheerleader. After a while, I don't know who pulled me out of the "timid kingdom" and forced me out. I initially tasted the feeling of flying! When I first put on roller skates, my body was shaking all the time, and I couldn't stand steadily like a drunk. The counselor next to him said, "Standing in a figure of eight will be stable." I tried my best and stood firm. Xuan Si flew up: "Your head, arms and legs are covered with pads. What are you afraid of? " So, I took a deep breath, closed my eyes and let my open feet slide out hard! Look up, bend over, kick, over and over again ... I'm finally cold. Brave, these two words stand out in me.
The next night, we came to the square again. I saw groups of people in the square, dancing, walking and skating ... varied, and the square was like a sea of festivals, very lively. Menstruation says, "Xuan Si, can't you dance Latin? Jump! " Xuan Si jumped up, dancing generously, shouting the beat in his mouth. At this time, more and more people are watching, and adults are pointing fingers. In a short time, Xuan Si finished dancing and the adults applauded warmly. "Sisi, you jump with it." Mom asked this question. How dare I, in full view! My face suddenly turned into a red apple. I begged Xuan Si, "If you jump again, I'll go up." In fact, how I wish she would dance slowly, slowly, so that I can escape. "Jump up, jump up!" The voices of adults urged me to break out in a cold sweat from time to time. "ah! Jump, lest you let your mother down. " I walked up slowly, jumping and encouraging myself. This square is like a living room at home. How to practice at home? Just jump the box. Thinking about it, my courage increased a lot, so I moved my hand, twisted my waist, crossed my legs and turned my head, and I was very happy. Then, Xuan Si danced the Latin swing dance. At this time, she and I danced together like clockwork, and the feeling of timidity was forgotten. Bold, these two words stand out on me again.
People cannot do without exercise. Exercise your will and courage from an early age, and when you grow up, you will have a sound personality and do everything in a down-to-earth manner. This is the biggest gain of my summer vacation!
I am an ordinary person, not a rich boy or a genius. I wear glasses and have short hair. I am a very ordinary person. Although I am an ordinary person, I have a habit that many people don't have-insisting on physical exercise.
When I was a child, I thought learning was the most important thing, but physical education was not important. Physical education was a bad subject. But this idea didn't last long. It disappeared on the day of the Beijing Olympic Games and was replaced by a new concept.
A few days before the Beijing Olympic Games, I couldn't help but have a boiling passion when I saw our athletes struggling hard on the field and winning glory for our country. Since then, an obvious idea has sprouted in my young mind. At the same time, my point of view has also changed, and I think that learning and physical education should be synchronized. If you want to study well, you must be in good health, because good health can make you study; If you want to be healthy, you must study hard, because if you study hard, you will have time to exercise.
Less than a year after the closing of the Olympic Games, I insisted on physical exercise. In those years, my life was full and I did the same thing almost every day. What you do every night is the same. Every night, I will find friends in the community, race together, jump rope together and play football together. Later, there was more homework and little time for exercise, so I had to do morning exercises more seriously and ask myself to walk faster.
At the age of eleven, my family also moved to "Nanyang Shi Sheng". This is an elevator apartment. There are not only elevators to sit on, but also stairs to climb. My salary is relatively high, so I came up with a way to exercise-I have to go to school in the morning and take the elevator if I am in a hurry. After school in the afternoon, take the stairs if you have time. I used a quarter of this coup and felt at a loss. I think this method is useless, so I came up with another method-first run from the ground floor to the top floor, then run downstairs, and then go home.
Sometimes, I also go to other buildings to run the "treadmill". This treadmill is made up of many iron columns, which are inclined by about 30. Once people stand up, they will slide down immediately, so they have to keep running, so they are called treadmills. Running in the community will never forget this treadmill. Every time I stand on it, it pushes me down, so I will keep running wildly; If you are tired of running, just hold the handrail and have a rest.
"The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold", and insisting on exercise is a song with eternal vitality; Insist on exercise, is it a person? The way to success. Sports are full of interest in people's lives.
Physical exercise contributes to health, and it is a good habit to insist on physical exercise. If you are good at sports, you can also take part in sports competitions. The spirit in these competitions is worth learning. Therefore, I love physical exercise.
Personal experience of physical exercise (3) The early morning wind gently brushed the willows on the roadside, and the sound of swish was intertwined with the sound of birds. The wicker is green and swaying in the wind, which is very pleasant. I rode my bike to Yan Di Park against the rising sun.
Today is the ninth day of summer vacation, and it is also the ninth day of my physical exercise. Speaking of sports, I can say that I hate it when I climb from 38 to 46. But what can we do? Both the senior high school entrance examination and physical education are 50 points, and you can't escape. So, from the first day of the holiday, I went to Yan Di Park to exercise, and was instructed by the PE teacher.
Arriving at the training site, I locked my car on the side of the road and began to warm up. After everyone arrived, the teacher announced that he would practice endurance today-keep skipping rope for three and a half minutes. My companion and I couldn't help crying and begging the teacher to show mercy. How terrible it is not to rest for three and a half minutes in a row! "This is clearly a nightmare!" I shouted in my mind. But the teacher automatically stopped our entreaties. Helpless, we had to stand in our seats and jump rope nervously, waiting for the nightmare to come. "Ready, let's go!" At the command, the five of us quickly threw up the rope. The fast rope is like a flying dragon. "Pa pa" rope landing, dusty; Whoosh, whoosh, whoosh, whoosh, whoosh, whoosh, whoosh. But gradually, I felt weak-my arms were shaking and my feet were tied with sandbags. My speed gradually slowed down. I forced myself to jump up, swinging my sore arm and continuing to jump rope. Beads of sweat appeared on my face. "There is still 1 minute!" The teacher's prompt gave me great motivation-because it's almost over, persistence is victory. I sent the last signal to my body. Whether my arm is sore or my breathing is not smooth, I have recovered my frequency and quickly threw the rope. "I'm so tired. Let's finish eating. I'm really tired!" My heart cries out in pain. Although it's morning, it's also the morning of July with scorching sun. "Stop!" The teacher's voice pulled me out of the quagmire of pain, and suddenly I was like a deflated ball, clutching my stomach, bending over and panting, and my feet seemed to be locked by chains and could not move. There seems to be a fire in my heart, burning, and I feel really uncomfortable.
"Get up, let's jump rope for a minute!" Before we had a rest, the teacher assigned us another task. Reluctantly, I got up from the ground, picked up the rope and stood back to the place where I had a nightmare just now. "Ready, let's go!" I quickly entered the state again, swinging the rope with my hands and jumping up and down with my feet ... A minute later, I jumped 163, with full marks.
My legs are sore, I am resting with water, and my heart is still vibrating at high frequency. The wind blowing from time to time makes me feel cool. I looked at the white clouds in the distance, recalled the feeling of skipping rope just now, and thought that I had been admitted to the whole school 12 through unremitting efforts. I felt that all this was very meaningful, although the process was very bitter.
Physical exercise continues, pain and fatigue will not dissipate, and so will life.
Personal experience of physical exercise (4) Physical education is an important part of education. I have at least 1 hour of physical exercise every day during my summer vacation. What are the advantages of insisting on physical exercise?
(1) Regular exercise can improve physical fitness and the ability to resist diseases.
(2) Physical exercise can promote bone strength and improve bone performance. Regular physical exercise can improve metabolism and change the structure and performance of bones.
(3) Insisting on physical exercise can also temper people's will, which is helpful to develop a persistent and persistent learning attitude. Only after physical exercise can they fully release their physical strength and concentrate more on reading and learning. Education experts have said that people who love sports are optimistic, which shows that proper exercise can cultivate good character.
Of course, we should also pay attention to several issues in physical exercise:
First, it is not advisable to exercise on an empty stomach.
Long-term fasting exercise in the morning consumes a lot of energy in the body, which is not good for the body. It is best to start light activities after eating in moderation, so that the muscles, joints and internal organs that have rested for a night and have been in a quiet state for a long time can be actively moved.
Second, strenuous activities should not be carried out immediately after meals.
After a meal, a lot of blood flows to the digestive system. At this time, if strenuous exercise is carried out, blood will flow to the motor organs to ensure the needs of muscle work, resulting in insufficient blood supply to the digestive system.
Gastrointestinal peristalsis slows down, which affects the normal progress of digestion and absorption, and can seriously lead to stomach pain, indigestion, ulcers and other diseases. Generally, it is reasonable to exercise at 0.5 ~ 1 hour after meals.
Third, it is not advisable to take a bath immediately after strenuous exercise.
Because exercise consumes a lot of energy, you must wait until the functions of various systems of the human body return to normal (about half an hour) before taking a bath.
Health is the foundation of life. For the sake of our health, let's insist on proper physical exercise every day.
Personal experience of physical exercise (Chapter 5) I exercise "squatting by the wall" every day, and I have four feelings and experiences about it. First, I should establish the concept of healthy living and healthy exercise; The second is to have a good attitude; The third is to have firm perseverance. The fourth is to pay attention to the quality of sports. I wrote two aspects a few days ago, you can refer to them.
1. Establish a healthy life concept and a healthy sports concept. I feel from the bottom of my heart that I am trading my hard work and sweat every day for a healthier body tomorrow. I want to learn to invest in health, sweat more, bleed less or not at ordinary times. With this idea, we can develop our habits into nature and integrate our ideas into our daily exercise without regret.
2. Have a good attitude. Because every morning exercise seems to repeat monotonous movements, from boredom, loneliness and loneliness in the early stage of exercise to the same scene now, irreversible psychological changes have taken place, and the mood has become quiet and full. In the face of loneliness, I no longer want to escape, but endure loneliness, be willing to be lonely, unfold my own spiritual touch in loneliness, let real life pass in my mind like a movie, and record my conversation with myself in my heart. The messy real life may become very organized, and things with internal regularity may surface. This is the exercise of "solitude" ability. Talking and discussing with people is small talk; Traveling with people is traveling. Only when a person is exercising, enjoying everyone's works, or facing the mountains and seas, is the beginning of "solitude" and "self-seeking" in the true sense, and it is also the beginning of soul life.
Personal experience of physical exercise (Chapter VI) Since we learned to walk, we started a lifelong sports career. Running and jumping are basic, and then we came into contact with various sports after entering school. Naturally, we have a lot of experience in this process.
Physiologically speaking, exercise can coordinate all parts of our body and make our reactions more sensitive, which is one of the most remarkable effects of physical exercise. Last school year, I took part in two ball games, football and basketball, to exercise people's lower limbs and upper limbs respectively. But there is no doubt that, although there is some emphasis, both sports need the coordination of the whole body, and the completion of sports is mainly the result of a certain muscle group coordinating contraction and acting on the bone marrow. Although football pays attention to footwork, without the cooperation of upper limbs, it is difficult to keep the balance of the body, and it is even more difficult to grasp the ball accurately, not to mention the meridian head muscles directly used for heading. Moreover, in the process of this sport, we must always concentrate, which requires high flexibility of the body. Similarly, although basketball needs the movements of the upper limbs, it also needs the running of the lower limbs. Without the coordination and unity of all parts of the body, it is impossible to complete this action smoothly. Regular physical exercise can obviously improve the analysis, synthesis and control ability of the nervous system. When people are exercising, the spatial position and muscle contraction of various parts of the body are constantly changing. The changes of these information are transmitted to the central nervous system in the form of nerve impulses, reaching the designated sensory area of the cerebral cortex, producing corresponding feelings. Through the systematic analysis and comprehensive action of the central nervous system, the internal and external situations are frightened and the movements are controlled. Regular participation in sports and repeated reinforcement of certain stimulus information promote the improvement of human body's ability to analyze various senses, make it have keen muscle feelings, and thus ensure accurate and moderate movements. People who often take part in sports are flexible and agile in daily life, study and sports, with quick brain response and strong physical adaptability and working ability.
The swordsmanship learned this semester has further requirements for physical coordination. Every part of the body, even the muscles of the face, should be highly unified as needed. Only in this way can the pace of the body be beautiful. If basketball and football need the dynamic coordination of human body, then fencing is static knowledge. Although it needs the cooperation of the body when moving, it is sloppy and strict, because they are not pursuing the process but the result. As long as you can score the final perfect goal and pass the ball, you can play it at will, but fencing is not. Every movement is fixed, and you just need to adjust all parts of your body to meet these "rules". Therefore, it is necessary for all parts of your nerve and its mobilized muscles to operate flexibly. In the process of contact, it is not difficult to find that many people's movements are out of shape and look ridiculous, which has a lot to do with inattention during practice.
We often engage in sports activities, and the original intention is probably inseparable from health factors. According to the data, 6% of our health depends on ourselves, 15% on heredity, 10% on social factors, 8% on medical treatment and 7% on living environment and geographical and climatic conditions. Perhaps because of genetic reasons, I don't like sports very much, and I seldom take the initiative to exercise, so sports have become my weakness, and 60% of my health factors can't be grasped. With the growth of age and knowledge, I gradually realized the important role of exercise in health.
Health can be divided into physical and psychological aspects, and physical exercise has a positive impact on both aspects. Physiologically, with the persistence of physical exercise, the morphological structure and function of our heart are improving day by day, the structure and distribution of blood vessels are also becoming more and more quantitative, blood pressure and blood lipid tend to be optimized, and the oxygen capacity of blood is obviously increased. With the improvement of transportation system in our body, all parts of our body can operate more flexibly, and our respiratory system, digestive system, exercise system and so on have been greatly improved. Before the college entrance examination, I used to exercise under pressure for a while. During that time, I ran to school every morning. It is for this reason that I always get sick easily, and I never went to the drugstore to buy medicine once all winter. It can be seen that physical exercise has a magical effect on our health.
I'm afraid that the idiom "Walk a hundred paces after a meal, and live to be ninety-nine" and "Running water will not rot, and one family will not lag behind" is not uncommon in our daily life, which shows the importance of physical exercise to health. In the pre-Qin period, Bian Que founded a gymnastics activity called "Five Birds Play". His disciples can practice and live to ninety-nine every day, and finally die without illness, which can't be said to be the effect of diligent exercise. The most difficult thing for us to do in the process of participating in physical exercise is not to make persistent efforts, in other words, not to persist in physical exercise until the end. You know, the benefits of physical exercise can only be reflected in the process of accumulation. Three days of fishing and two days of drying nets can only make our efforts in vain. I am a good counterexample myself. After realizing the importance of physical exercise to us, let's make plans from now on and work hard from tomorrow!
Personal experience of physical exercise (Chapter VII) Life lies in exercise. A large number of theoretical and experimental studies show that regular and reasonable physical activities have a far-reaching impact on reducing whole body energy consumption, improving activity efficiency, maintaining vigorous energy, promoting the normal operation of various physiological functions, and cultivating physical strength and good habits.
College students should pay attention to long-term exercise and practice, maintain adequate nutrition and rest and sleep. The so-called exercise is to repeatedly carry out similar activities, produce systemic adaptive changes, and coordinate the activities of various tissues, organs and systems of the human body. The so-called exercise is to repeat similar activities many times on the basis of exercise, resulting in adaptive changes of the system and improving its efficiency. When human body is active, muscle activity is correspondingly strengthened, which has great influence on energy metabolism. No matter what kind of activity you are engaged in, your energy consumption is higher than its basic state, that is, higher than when you are awake and quiet. After long-term exercise and practice, the changes of breathing, circulation and metabolism caused by skilled skills and activities can be coordinated with the intensity and duration of activities, that is to say, the physiological state during activities completely meets the needs in the process of activities, that is, a stable activity stereotype is established. Exercise should have enough nutrition. To carry out any activity, the human body must pay a certain amount of energy and physical strength and consume a certain amount of energy. Energy comes from nutrients in various foods, such as protein, sugar and fat. These nutrients are the main providers of human energy. Pay attention to proper rest after exercise. Any physical activity may cause fatigue, especially high-speed, high-intensity and long-term physical activity, and fatigue appears earlier. Once you are tired, it means that you should stop your activities and have a rest. There are many ways to rest, such as dynamic rest, that is, changing a form of activity, or sitting down for entertainment to achieve the purpose of rest; You can also have a static rest, that is, play with tons or fall asleep. Sleep can effectively eliminate fatigue and protect physical strength. Exercise has endless benefits, the first is to dispel anxiety and refresh your mind. The best antidote to anxiety is exercise. When you are worried, use more muscles and less brains, and the result will surprise you. No one can do strenuous exercise in the gym or climb mountains, and still be upset about what just happened. No matter who you are, exercise can lift your spirits. Secondly, lose weight and exercise, improve insulin resistance, promote myocardial perfusion, reduce the risk of male stroke, enhance bone load and slow down osteoporosis.
Basketball is one of the most popular sports in universities now. Basketball courts are the most crowded when classes are over or holidays are over. Not only are there many people playing on the court, but there are also many people watching the ball off the court. For me, the choice of exercise object is nothing more than basketball. Playing basketball is not only because I like watching nba, but also because I exercise. Of course, there are many benefits of playing basketball. Playing basketball can train the brain's thinking and judgment ability, and train the speed of the body's secondary reflex action after thinking. Playing basketball can increase lung capacity and improve blood oxygen carrying capacity. Playing basketball can train eye vision and ear hearing sensitivity, train muscle activity and muscle strength of the whole body, train endurance and improve body shape. Training the coordination and agility of joints can also promote the bone development of growing young friends and make you grow taller. Playing basketball can enhance myocardial contractility and cardiac load capacity. Playing basketball speeds up the whole body's blood circulation and metabolism, and after replenishing a lot of water, it eliminates harmful wastes in the body through sweating and urination. After cleaning your body, your skin will be more shiny and elastic! Exercise promotes appetite and gastrointestinal motility.
In people's minds, football is a sport with fierce confrontation and endless charm. Although the competitiveness of football in China is not very strong at present, the charm and function of football cannot be ruled out. Football is also very popular in universities. Occasionally, I will choose a time to play football and run with my classmates on the playground. I played football since I was a child, and I also played football in my department until I went to college. Playing football has also made my originally thin body strong, also exercised my reaction ability, made many like-minded friends, and increased the friendship between friends. First of all, football can exercise coordination and flexibility, because football is a whole-body sport. In addition, including reaction ability and physical fitness, you can get different degrees of exercise. Secondly, as a team sport, he has incomparable charm for individual sports. Playing football from an early age can cultivate team consciousness, communication ability, cooperation ability and mutual trust, and let them know how to respect themselves and their opponents, how to win by collective strength, and how to treat the outcome. Football is a combination of running and leg exercise. During running, passing, shooting, etc. The depth of breathing will be strengthened, so that more oxygen will be inhaled and more carbon dioxide will be discharged, thus increasing vital capacity and strengthening lung function. Strengthen leg bones: Football is the best exercise to train legs. In the process of continuous leg movement, the blood supply of bones is improved due to the promotion of metabolism, and the morphological structure and function of bones have changed well: the bone density is thickened, which makes the bones thicker, the trabeculae of bones are arranged more orderly and regularly according to different pressures and tensions, and the protrusions attached to muscles on the bone surface are more obvious.
