Method: Players form a circle. At the beginning of the game, the teacher appointed anyone to start the game counterclockwise or clockwise. The first man said, "Basketball!" "At the same time, make your hands look like table tennis. The second person should go on to say, "Ping-pong! "At the same time, make your hands look like basketball. This is done alternately. If someone makes a mistake, they must perform a program for everyone. Then start with the person who made the mistake and continue the game.
Rule: ① You must speak and gesture at the same time. (2) Before and after the pause between two people can't be too long, otherwise it is a failure.
Teaching suggestion: You can also play games by saying that you are tall and thin and doing actions with the opposite meaning.
Two: "queue practice".
Method: Players form a circle. At the beginning of the game, the teacher appointed anyone to start the game counterclockwise or clockwise. The first man said, "Attention!" "At the same time, behave at ease. The second person should go on to say, "At ease! "At the same time, let it pay attention to observation. . The third person should go on to say, "turn left!" " "Turn right at the same time. The fourth man went on to say, "Turn right" and turn left at the same time. This is done alternately. If someone makes a mistake, they must perform a program for everyone. Then start with the person who made the mistake and continue the game.
Rules: ① Words and actions must be carried out simultaneously. (2) Before and after the pause between two people can't be too long, otherwise it is a failure.
Three: "refers to the part."
Method: The player points the index finger to the tip of the nose. At the beginning of the game, players must give themselves seven passwords in succession, such as "eyes-ears-hair-mouth-eyebrows-teeth-throat" and so on. When giving each password, the index finger must point to the wrong part. As long as one of the seven passwords is consistent with words and deeds. Failed, the loser must perform a program for everyone.
Rule: the action must be clear and in place, otherwise it is a failure.
Extended data:
How to carry out the preparatory activities?
Generally speaking, the content, time and quantity of preparation activities are mainly considered.
content
Preparatory activities can be divided into general preparatory activities and special preparatory activities. The general warm-up activities are mainly some general physical exercises, including running, kicking and bending. General warm-up activities can improve the overall metabolic level and the excitement of cerebral cortex, and reduce the occurrence of sports injuries. Special warm-up activities refer to physical exercises that are adapted to the content of physical exercises, such as shooting and dribbling before playing basketball and jogging before running. Unless there are some special sports and competitions, ordinary people only need to carry out general preparatory activities when exercising, and then they can carry out formal sports activities.
Time and quantity
The amount and time of warm-up activities depend on the content and amount of physical exercise. Because the amount of exercise in fitness is small, the amount of warm-up activities is also relatively small, and the time should not be too long. Otherwise, you will be very tired if you don't exercise. For half an hour's physical exercise, the preparation time is generally around 10 minutes. When the temperature is low, it takes a long time to prepare for activities, and the amount can be larger. When the temperature is high, the time can be shorter and the amount can be smaller.
There should be a time interval.
Unlike athletes who formally participate in competitions, ordinary people can do physical exercise immediately after warm-up activities. The proper rest of athletes after warm-up activities is to restore their physical function and create excellent results in the competition. However, most people take part in sports activities in order to strengthen their physique, not to create achievements, so they can take physical exercise after preparing for the activities.
Physiological function of warm-up activities
Adjust the pre-match state
Warm-up activities can improve the excitability of the central nervous system, adjust the bad pre-competition state, speed up the brain's reaction speed, coordinate the sports centers participating in the activities, and prepare for the physiological function to reach an appropriate level quickly in formal practice or competition.
In order to overcome the physiological inertia of internal organs
Through warm-up activities, we can improve the functional level of cardiovascular system and respiratory system, increase lung ventilation and cardiac output, expand the capillary network of myocardium and skeletal muscle, and make working muscles get more oxygen. So as to overcome physiological inertia of viscera and shorten working time.
Improve the metabolic level of the body and raise the body temperature.
The increase of body temperature can reduce muscle viscosity, increase muscle contraction and relaxation speed and increase muscle strength; At higher body temperature, hemoglobin and myoglobin can release more oxygen and increase the oxygen supply to muscles.
The increase of body temperature can increase the activity of enzymes in the body, improve the level of substance metabolism and ensure adequate energy supply during exercise; Elevated body temperature can also improve the excitability of central nervous system and muscle tissue; At the same time, the increase of body temperature increases the ductility, flexibility and elasticity of muscles, thus preventing sports injuries.
Physiological mechanism
Through the pre-performed muscle activity, there are traces of improvement in excitability in the corresponding parts of the nerve center. The physiological effect produced by this trace can make the excitability of the central nervous system at the most suitable level, improve the regulatory function, overcome the functional inertia of internal organs, accelerate metabolism, and help the body to be at the best functional level.
However, the trace effect does not last long. After 45 minutes of preparation, the trace effect will all disappear.
The time, intensity, content and time interval between warm-up activities and formal sports or competitions are all factors that affect the physiological effect of warm-up activities. Generally speaking, the intensity of warm-up activities is 45%VO2max intensity, the heart rate reaches 100- 120 beats/min, and the time is between 10-30 minutes.
In addition, it should be adjusted according to the characteristics of the project, personal habits, training level and seasonal climate, and it is usually appropriate to sweat slightly and feel active. The interval between the end of warm-up activities and the start of formal practice is generally not more than 15 minutes. 2-3 minutes is suitable for the preparation activities of general teaching classes.
