What are the precautions for playing football?

Precautions for Playing Football Speaking of football, I believe many boys like it very much. Playing football can make our bodies healthier, but playing football also needs to pay attention to some matters. Here are some precautions for playing football! Points for attention in kicking 1 kicking tips 1. Players' health care-drinking water is a common thing in commercial competitions. At the rest or end of the game, players will drink a lot of water because they feel thirsty, and even go to the tap to take a big drink. This instant satisfaction often has a bad influence on the body, because strenuous exercise consumes a lot of the body and the functions of all parts are at a relatively low level. At this time, if you drink a lot of water, it will inevitably cause the heart to be overburdened. Drinking a lot of raw water and cold water will also stimulate the stomach and cause "stomach pain", which is not good for the body. The correct way is to drink a small amount of water after strenuous exercise, and then increase the amount of water after a period of rest to avoid drinking raw water and cold water. 2. Players' health care-the harm of swallowing. Whether for ordinary people or football players, swallowing should not be advocated. The difference is that ordinary people are not encouraged to smoke, just for health, and for football fans, there are also factors to improve their sports ability and competitive level. The most direct harm of smoking to the improvement of football players' competitive level mainly lies in reducing the maximum oxygen uptake level, a typical index of athletes' aerobic endurance (general endurance). There are two main reasons for this result. (1) Smoking reduces lung ventilation: The maximum oxygen intake is determined by the levels of inhaled oxygen, transported oxygen and utilized oxygen, and lung ventilation is an integral part of inhaled oxygen. Because smoking will increase respiratory resistance and affect the amount of air in and out of the lungs, it is inevitable to feed it with inhaled oxygen, which will affect the maximum oxygen uptake and lead to the decline of exercise ability. (2) Smoking makes the oxygen uptake of hemoglobin diffuse from alveoli to blood, which is mainly combined with hemoglobin in red blood cells and transported to various organs and tissues. Because the inhaled smoke contains carbon monoxide, its binding capacity with hemoglobin is several times stronger than that with oxygen, which will inevitably lead to a decline in the binding capacity between hemoglobin and oxygen, so the maximum intake will also be affected. According to scientific measurement, the respiratory resistance of long-term smokers is 1 times greater than that of non-smokers. If you quit smoking 24 hours before exercise, the respiratory resistance will be reduced, and even not smoking on the same day will help restore your competitive ability. Therefore, football players had better not smoke. 3, player health care-bathing Many athletes take a bath immediately after practice or competition, thinking that this can not only decontaminate but also eliminate fatigue. In fact, this practice is not scientific, because during exercise, the blood flowing to the muscles increases and the heart rate is recalled. After stopping exercise, this situation will continue for some time. If you take a hot bath at this time, the blood will not be enough to supply other important organs, such as the heart and brain, and you will feel dizzy, nausea, general weakness and even other diseases, so pay special attention. Taking a cold bath immediately after exercise does more harm than good. Because the metabolic process of the body is strengthened during exercise, the subcutaneous blood vessels dilate and sweat a lot. Take a cold bath immediately after exercise, so that a lot of heat generated in the body can not be dissipated well, forming internal heat and external cooling, destroying the balance of the human body and easily getting sick. The correct way is to take a rest after exercise (subject to the pulse returning to near normal number), and then take a bath, preferably a warm bath. Precautions for playing football 2 1. Get ready for activities. If your feet itch again, don't kick directly. It takes at least 10 minutes to prepare for the exercise. You can jog for a while, move your ankles and knees, make your body sweat slightly, pull apart joints and ligaments, and move your ankles, knees, wrists and hips. All sports will be used. People who don't exercise for a long time should do warm-up activities. In this way, it not only contributes to the efficiency of muscle activity and the lubrication of joints, but also prevents sports injuries. 2. Because there is a lot of running during exercise, the technical movement range and sweating amount are relatively large, so you should wear loose, breathable and sweat-absorbing sportswear during exercise, and the sneakers are preferably football shoes with non-slip canvas shoes and rubber soles. In addition to participating in formal competitions, it is not advisable to wear shoes (leather nails) in normal football matches to prevent unnecessary harm to yourself or others. If you are playing a more formal game, it is recommended to bring leg pads and other protective gear, and don't use too much force when playing. It's a hot day, just means it. Try not to exercise in places where the facilities do not meet the requirements. Uneven ground and many sundries (runways and bunkers) are easy to cause ankle sprain, periosteum injury and achilles tendon strain. 4. Replenish water in time. It's best to put the water aside and drink a little when you feel thirsty. It doesn't matter if you drink more times. Don't wait until you are too tired to drink a lot at once. Remember not to drink long-lasting drinks, raw water or cold water, and cool mineral water is the best. You can drink a small amount of sports drinks or salt water after exercise. Although football is an all-weather sport, try to avoid sports in bad weather. Pay attention to prevent heatstroke, cramps or collapse when it is hot and humid. Keep warm when it is cold and wet to prevent frostbite. At dusk and dawn (especially in foggy days), due to insufficient light, low visibility, slow nerve response and reduced excitement, injuries are prone to occur. Rainy days and slippery ground are also important reasons for injuries. 6. You'd better have a pair of slippers. It will be very comfortable to wear them after kicking, even better if you bring a towel to wipe your sweat. 7. Finally, remind everyone to try to play football in the morning or evening when the sun is weak. Also, if your skills are not good enough, don't deliberately imitate the difficult movements of stars. Otherwise, it's not worth it to delay your study and work because of a little injury! Improve the action practice of fast dribbling 1, dial the ball from left foot to right foot, and then dial it from right foot to left foot, and move forward with the ball in a snake shape. This can exercise the ability to control the moving ball. 2. Pull the ball with the inside of the instep of the left foot, change the direction of the body, and gently touch the ball again. Then pull the ball with the inside of the instep of your right foot. This can improve the ability to change the ball speed. 3. Pull the ball to the inside of the instep of the left foot with the toe of the right foot. After touching the ball lightly, pull it to the right with your left toe. 4. Pick the ball with the inside of the instep of the right foot and roll horizontally (in fact, it is what fans and friends often say "spike"). After touching the ball again, use your left foot. When doing this exercise, be sure to make the ball roll horizontally after picking it up. If the ball rolls forward obliquely, it will fail to pick up the ball this time, because the defender can easily break the ball. 5. Pull the ball back with the sole of your right foot. After the right foot touches the ball twice, change the left foot and practice in situ. This action is often used when protecting the ball, so friends who are strong or play forward should practice more. 6. Put your left foot on the ball, turn around quickly, put on your right foot and step on the football, then kick the ball out on the outside of the instep of your right foot. After touching the ball again, practice repeatedly with your right foot. I think this action is not unfamiliar to friends who like Danish football, because the captain of the Danish national football team scored a goal in this way in the World Cup in the mid-1990s. 7. Pull the ball backwards with the toe of the left foot, then push the ball backwards with the inside of the instep of the right foot, and then push the ball out with the instep. After touching the ball again, repeat the exercise with your right foot. Maintenance of football 1, usually inflate the ball with water or soapy water. Before inserting the air pump needle, it is usually wetted with water or soapy water. A dry air pump needle may damage the airbag valve, resulting in air leakage. Pull it up bit by bit. Pump up slowly and let the ball swell up gradually. If a compressor or similar equipment is used to forcibly inject a large amount of air, the airbag valve will collide with the suture line, causing the ball to break. Obeying expansion means that excessive expansion will cause the ball to deform or expand. Observe the air pressure regulations indicated on the valve opening. If you adjust the air pressure, you can keep your molten ball in the best condition when you need it most. 2. Check for air leakage. Washing sand or dust into the air valve with soapy water can easily lead to air leakage. Be sure to wash it carefully with soapy water. After cleaning, rinse off. When a new ball is inflated for the first time, air will leak from the ball pin. This is just the air filled between the bladder and the liner when making balls. This is completely normal and does not mean air leakage. Let the air out after the game. Because the ball is often inflated before the game, it should be deflated after the game. When the ball is not used, it always maintains a high air pressure, which will lead to expansion and deformation. After brushing the surface, use a brush to sweep away the sediment in the ball joint. Wipe the surface with a soft wet cloth. 4. Plastic balls also need maintenance. Plastic balls do not need to be deflated after use. However, be careful not to scrub the surface with anything containing grease or solvent. These substances will penetrate into the seams of leather, make the leather deteriorate, and cause the leather to fall off. Please follow the following methods for safekeeping and storage (1). After use in rainy days, wipe it clean and put it in a cool place to dry. (2) Keep the ball in a dry and ventilated place to avoid direct sunlight. Keep the ball away from sharp objects, such as barbed wire, broken metal mesh, rose thorns, cactus or other things that may pierce the ball. Some small holes that are invisible to the naked eye may cause air leakage. Don't expose the ball to direct sunlight for a long time. Keep the ball away from overheating and humidity. Whether it is natural leather or synthetic leather, don't wipe the surface of the ball with benzene. Football technology 1, pinball technology is one of the most basic technologies in football, which mainly requires players to have a good sense of the ball when playing football, control the football well when playing football, and let the football run in the way they want. Generally, kick the ball with the inside of the foot, the knee joint of the supporting leg flexes slightly, and the center of gravity of the body moves to the supporting foot. When the ball falls to the height of the knee joint, the ball bends cross-legged, the inside of the foot swings upward, the foot turns inward (the inside of the foot is in a horizontal state), and the ball bounces upward by lightly hitting the bottom of the ball. 2. Passing skills Passing skills are more important in football skills. It is a link between sports chains on the football field. The passing skill directly determines the passing quality. In actual competition, there are many factors that determine the quality of passing, such as the control of passing direction, the control of foot strength and contact point, followed by a good grasp of time, action and coordination. One of the biggest changes is also the most difficult to master, controlling the route and rotation of football. 3. Passing skills There are many passing skills in football. The specific passing skills should be used according to their own technical characteristics and market conditions. There are two kinds commonly used, steering and speed change. 4, * Door skill drawing * is a basic skill in football, and it is also a difficult technique to master. When drawing *, the football player draws the ball with the instep. Because at this time, the ball can give full play, with great strength and speed, it is difficult for the goalkeeper to make an effective save. But the requirements for athletes are also very high: first of all, athletes should seize the opportunity to pull their feet when the ball is at a suitable distance from their bodies. If the body is too close to the ball, they can't stretch, so they can't have great strength. 5, stop the ball technology football can not keep moving on the court forever. Football must stop and go, so it will stop when the ball is about to move. In football, all parts of the body can be used to stop the ball except the arm. It should be noted that when stopping the ball, you should stop the ball in a suitable position far away from your body, so that it will not only be broken by your opponent, but also be conducive to the completion of your next technical action. This kind of suspension is standard and appropriate. 6. Grab the ball. Football is a sport that pays attention to the balance between attack and defense. While playing football, it must also defend and stop the opponent's attack. So for football players, grabbing the ball is also a basic football technique. Grab the ball definitely requires the defender to grab the ball, mainly through defense to stop the opponent's attack.
