On the application of volleyball games in college sports volleyball teaching

Volleyball has a long history all over the world. In recent years, China’s women’s volleyball team has won the championship frequently, which has attracted widespread attention. More and more students are participating in volleyball games. Volleyball has many advantages, for example, it can strengthen students’ physique, and mutual competition among teams can improve students’ teamwork ability and competitive enthusiasm, which is conducive to students’ comprehensive development. However, at present, most colleges and universities still follow the traditional teaching mode, and most physical education teachers lack understanding of the importance of volleyball games and practical experience, and most of them teach students theoretical knowledge and basic competitive skills, which makes volleyball courses in colleges and universities lack relevant educational significance.
First, the educational value of volleyball games to college students
(A) Volleyball games help to stimulate students’ interest in learning volleyball.
According to the survey, most students like to play autonomous volleyball, but they are less interested in volleyball courses. The main reason is that the teaching content of volleyball courses is boring and monotonous, and it also limits students’ freedom. On the contrary, volleyball games can fully show themselves during the game, and the game is competitive, so students will be more active. The application of volleyball games can stimulate students’ interest in learning volleyball, which can not only effectively accomplish the teaching objectives of physical education teachers, but also greatly improve students’ physical fitness.
(B) is conducive to cultivating students’ enthusiasm for competition and teamwork.
Volleyball games are mainly based on competition. Competing among groups can stimulate students’ competitiveness, and volleyball requires the cooperation of many people in groups, so it can also improve the teamwork ability of college students, which is conducive to the healthy and all-round development of college students and conforms to the current environment of quality education reform.
Second, the application strategy of volleyball games in college sports volleyball teaching
With the development of ball games at home and abroad, it is necessary to pay more attention to volleyball teaching in colleges and universities. Especially with the continuous reform of education, college sports volleyball teaching should return games to teaching, use volleyball games to assist volleyball teaching, and at the same time pay attention to the educational value and fitness function of volleyball.
(A) improve the adaptability of the game
The purpose of volleyball games is mainly to cooperate with volleyball teaching, so teachers should still focus on teaching objectives and choose suitable games according to students’ characteristics, including fully considering students’ volleyball foundation and skills, as well as the length of time for students to study volleyball courses. In short-term volleyball teaching, physical education teachers can make students repeatedly train in the same game or the same game, in order to let students master a specific action or skill. In the long-term teaching, the content of the game can be continuously enriched, and students can master more comprehensive volleyball skills.
(2) Adjust the difficulty of the game appropriately.
After a period of practice, students’ mastery of basic volleyball skills will be improved accordingly. However, if students are always trained in games with lower difficulty, it is difficult for them to improve greatly. Therefore, teachers can adjust the difficulty of volleyball games appropriately according to their mastery. However, at present, many college teachers do not have much research on volleyball games, and the game mode adopted is relatively simple. Therefore, teachers need to pay more attention to it and develop volleyball games with moderate difficulty for students to practice.
(C) changing game patterns to improve students’ enthusiasm for participation
After repeated practice of a single game, students will inevitably feel boring. Over time, students lose interest in volleyball. Therefore, teachers need to constantly change the pattern of volleyball games, for example, by changing the number of students forming teams or the number of competitors to increase the interest of the game, which is also conducive to improving the enthusiasm of students to participate in the game. At the same time, teachers can also formulate reward and punishment measures to provide certain rewards to the winning team, while the losing team can be punished for practicing certain volleyball movements. Reward and punishment measures can not only motivate students to be more competitive, but also improve their mastery of basic volleyball movements.
(four) to ensure the safety of the game
In colleges and universities, there are many students in physical education class at the same time, and the danger of volleyball is also high, which is limited by many factors such as venue infrastructure. Students who are new to volleyball should not be required to practice immediately, otherwise it will easily lead to injuries due to improper movements. In addition, teachers should carefully check whether the volleyball court is flat and whether the relevant equipment is safe before class, and ask students to wear sportswear to avoid strain caused by excessive movement.
(5) Formulating the rules of volleyball games and strictly observing them.
Any kind of game needs strict rules as the basis for judging the outcome, and students are required to strictly abide by the relevant rules when playing volleyball games. In the case of less volleyball venues, teachers should allocate groups reasonably and organize all students to participate in the game to ensure the fairness and discipline of the game. Teachers, as judges, also need to enforce the law impartially and not take sides, so as to ensure the normal development of volleyball games.
Third, the conclusion
To sum up, the application of volleyball games can greatly improve the effect of volleyball teaching in colleges and universities, and it is of great significance to the growth and development of students. In the environment of quality education reform, college teachers should innovate teaching methods and enrich teaching contents, and physical education teaching can also incorporate appropriate game elements, so that students can not only learn volleyball related knowledge in a relaxed environment, but also spontaneously consolidate their competitive skills. In addition, the development of students’ volleyball game activities can also improve their team cooperation ability, which is conducive to improving students’ comprehensive quality and making students have a healthier body and mind.

Winter food, winter dates and chestnuts, the original heat is not "good stubble"!

  Unconsciously, it’s winter again. Pedestrians wearing thin down jackets pass by on the street. Dried fruit roasted seeds and nuts shops on the roadside seem to warm people’s hearts. Crispy winter dates ~ waxy chestnuts ~ enter their mouths, and one after another can’t stop. Hmm ~ only children do multiple-choice questions, but adults do! Boss, one catty each! If I don’t eat them this season, I feel sorry for waiting for them for a year! Fat can be reduced in two months, but winter dates and chestnuts will be gone in two months!

  Today, let’s take a look at the main nutritional components of winter jujube and chestnut, so as to avoid the introspection of "growing stronger and stronger for no reason" next spring. In fact, winter dates and chestnuts are not "good stubble" of heat.

  "Compendium of Materia Medica" records: "Jujube is sweet, non-toxic, calming the middle and nourishing the spleen, calming the stomach and clearing the nine orifices." Therefore, jujube has become a treasure in fruit because it integrates medicine, health care and eating. In daily life, dates can also be seen everywhere (blood, iron and qi), and winter dates are the "uncrowned king" of vitamin C. The vitamin C content of 100g fresh winter jujube is about 300mg, which is about 10 times that of citrus, 50 times that of pear and 70 times that of apple. The weight of a fresh winter jujube is about 15g, and the edible part is 87%. Those three fresh winter jujubes can provide about 100mg of vitamin C, while the recommended intake of VC for normal adults is 100 mg/ day. Of course, in addition to vitamin C, Dongzao has other "nutritional weapons", such as jujube flavonoids, cyclic adenosine monophosphate, triterpenoids and other plant compounds. These active ingredients can play an important role in anti-oxidation, anti-aging, immunity improvement, anti-cancer and anti-fatigue.

  However, winter jujube is not such an "angel". First of all, the calorie of winter jujube is not low. If winter jujube is used as a fruit to add meals, it is best not to exceed 100g every day, which is about 6-7 pieces in normal size. At the same time, we should pay attention to the changes of blood sugar. Secondly, the dietary fiber content of winter jujube is higher than other common fruits (grapes, apples, etc.), which is easy to cause gastrointestinal discomfort such as bloating; Finally, the peel of winter jujube is crisp and thin, so it is difficult to chew it fully when chewing. The peel (or stone) with sharp edges is often swallowed into the digestive tract, which is easy to cause pain or discomfort of stomach lesions and even life-threatening.

  For chestnuts, the calories of a handful of chestnuts (about 10 chestnuts, about 110g edible parts) are equivalent to that of a bowl of cooked rice with 200g carbohydrate, which is not as much as the "two or two meals" in the canteen. Because the content of protein and fat in chestnuts is slightly higher than that in rice, and there are more oligosaccharides and resistant starch that are not absorbed by small intestine, the GI index (glycemic index) is lower than that in rice, which is more friendly to people who need to control blood sugar. On the other hand, these unabsorbed dietary fibers can easily make people feel bloating, so people with poor digestive function should pay attention to eating less, especially avoiding eating raw chestnuts. At the same time, try to eat hot cooked chestnuts and stew meat with chestnuts.

  Having said that, I actually want to tell you that when winter comes, those "winter fat" who can’t be returned for 7 days without reason may find some answers in the crunchy and silly sweetness of this mouthful.

Wild fishing, you can’t catch big fish, do you make the same mistake?

Wild fishing, you can’t catch big fish, do you make the same mistake?

Everyone basically knows what wild fishing is. The simple understanding is that in addition to artificial cultivation ponds, we can fish in the water in the natural environment. We collectively referred to as wild fishing.

Although wild fishing is better in environmental and quality than artificial breeding. Perhaps it tastes much better in taste.

However, because of the wide area, the density of the fish is relatively poor, and the hook rate is far less than that of the pond.

Therefore, wild fishing wants to catch big fish in the rare environment of its own fish, so we must pay attention to the following points:

Share with everyone here, I hope to help fishermen.

The fish in the wild is more vigilant than the home -raising fish. After all, the alert fish with low vigilance has been fishing.

With a little movement around, the fish will be scared away, and the courage is particularly small.

So, if we want to catch big fish, we must stay away from the crowd, traffic, and find a place with less noise or no noise.

Set your phone to mute, and speak softly to speak, maintain a certain silence, and use tools when making nests, such as the nesting device.

Some fishermen are in the mood of being eager to catch fish in order to miss any wind and grass, and adjust their sensitivity high.

But knowing that you ca n’t eat hot tofu, in fact, this is a do not lose money. It is because it is too sensitive. If you just move, you will mistake you to think that there is a fish hook, which will cause frequent rods. This will definitely affect fishing. It will definitely affect fishing. Caused fish to be counterproductive, so sometimes it cannot be tuned too sensitive.

In order to make the effect of the fish attracting the fish, most fishermen will add some atomized materials to the bait.

Make the atomization more three -dimensional and highlight. In fact, there is no problem with fishing fish in this way. If it is used to catch big fish, it will have some effects.

Because the effect of atomization has increased, there are more small miscellaneous fish, and the bait is eaten by the small fish, and the big fish will not come over.

When the fish speaks, it is difficult to know. Some people with acute children will constantly change bait and want the fish to eat.

There is a problem. If you keep changing the bait, it will cause the fish to be vigilant. The fish is not stupid. If you change it, it will cause the fish to not speak, and the big fish will not be available. Try to avoid using this type. The bait.

In order to avoid this situation, we can spray a few times when we bait.

Because Qi Muyu is very rich in lure fish.

Especially in freshwater fish, many hormones, fish steroids, and multiple vitamins are added with freshwater fish. After the fish smells the taste, it will appetite and increase appetite.

Even when the fish itself is not hungry, the fish will have the desire to eat.

There is also a very good role in leaving fish. This taste will be kept in the water for a long time, and it will not disperse.

It can effectively attract big fish and improve the hit rate.

No matter what bait you use, it is more taboo to change frequently, raising the pole.

However, in terms of cost -effectiveness or quality, Qi Mu high -carbon pole fishing. Will reduce a certain loss for you.

Qi Mu’s high carbon pole is really friendly to fishing friends. Material is made of high -tonnage carbon cloth. It holds lighter in hand, has a good waist strength, and is not easy to break.

I don’t lose the brand in my hand, even if it is fishing for a day, it won’t be tired. Whether the big fish or the small fish can catch it in seconds.

Qi Mu’s high carbon pole belongs to a comprehensive rod of 28, which can adapt to a variety of venues, light texture, easy to carry, fashionable appearance, and basically cannot run after the fish hooks. It is a good fishing rod.

The above -mentioned precautions must be clearly understood. These issues will have more chances of making mistakes in novices. As for some fishermen who live in fishing ground for a long time, they can be used as a reference. After all, everyone’s habits are different. Make copy, randomly strain according to the actual situation.

Also, as a fellow fishing fellow, we should remember mistakes and change flexibly. We should do fishing for fishing.

After we get a big harvest, we can release some, instead of taking away all the brains. This will not only destroy the ecological environment, but also affect the harvest of fishing in the future.

Everyone can be able to release appropriately, so I think every harvest can be rich.

The most important point is that we must take away the garbage when we fish, because everyone is responsible for the environment.

During fishing, garbage everywhere will also affect our mood and the harvest of fishing.
