Technical characteristics of the sprint.
Sprinting techniques are constantly evolving, and at the beginning of the 20th century, the running technique was the "step" running method, which was characterized by a large forward torso, high thighs, and a small stride near the projection point of the body's center of gravity. Finn Krimet created"Swing"The running technique is characterized by the upper body standing upright or leaning forward slightly, the thighs are raised, the heels are on the ground, and the landing point is far from the projection point of the body's center of gravity.
Both of these landings affect the development of the athlete's speed with the heel. According to the research of the Swedish Institute of Sport, the heel landing should be changed to the forefoot landing, resulting in a new one"Swing"Running style. The emergence of modern plastic runways has led people to gradually improve their technology and begin to adopt the swing type"Flexion type"Running method, reduce the angle of kicking, and strengthen the effectiveness of kicking.
With the progress of the times and the development of science, people have gradually adopted qualitative analysis, quantitative analysis, model analysis, computer simulation and other means of sprinting technology and training, so that people's understanding of sprinting technology has been continuously improved, and the knowledge of various disciplines such as sports biochemistry, sports anatomy, sports biomechanics, systems engineering and other disciplines has crossed with each other, enriching people's understanding of the sprint project, therefore, the sprinting teaching and training methods have been continuously enriched, improved and innovated.
1 Technical features.
1) The movement is fast and flexible, the body movement speed is fast, the displacement speed is fast, and the action is light and dexterous.
2) The explosive force of muscle contraction is strong and the force is high when doing movements. In particular, the relative strength and muscle elasticity are good, because without a certain strength as the foundation, the muscles cannot produce strong explosive force.
3) The running action is coordinated, the upper and lower limbs are well coordinated, the force action is reasonable, and the forward effect is good. With the gradual popularization of plastic runways, the technology of modern running basically belongs to the category of swing running, emphasizing that the hips are actively sent when swinging, the forefoot is actively grabbing the ground when landing, and the "flexing pedal" is "bent and pedaled" when pedaling. From the point of view of the appearance of the running movement, the main characteristics of modern sprinting technology are to run relaxed, the whole movement is light and soft, natural and coordinated, the stride is open, and the forward performance is good.
In addition, the technical study and training of sprinting should be continuously improved on the basis of the coordinated development of technology and quality, find out the contradictions in the imbalance of technology and quality, obtain a certain balance through training to improve performance, and then break this balance to seek new development and new balance. Sprint training is to continuously improve the quality of teaching and training through this method.

There are many characteristics of running sports, which ones do you know? Running is a popular sport. Regular running can bring many health benefits.
Running helps to strengthen bones, strengthen muscles, and improve cardiovascular health. At the same time, it can also help us burn calories.
Maintain a healthy weight. The following describes the characteristics of running sports.
For the most part, running is an individual sport. It is different from team sports such as football. Long solo runs can build mental toughness.
Most runners focus on themselves, not others, including your breathing, speed and pace. You don't need to communicate with others while running. Carrying Sakura to stop some runners, I like to listen to the sounds around me.
Running is a simple sport, especially for amateurs. When running, you don't need a lot of equipment, for example, helmets and rackets. All you need is a pair of running shoes, and you're good to go.
It also doesn't need to cost too much. This is also one of the characteristics of running.
When we run, we repeat the same movements. For example, you plan to run 5 km. During this process, if you are not patient enough, you may get bored and want to stop.
If you take off your headphones and focus on your breathing, it seems to become, a meditative moment. If you can't run because of an injury, it can also test your patience. Successful runners also need enough perseverance.
They will persevere, and eventually, they will rush to the finish line, for example, in a marathon. It helps us to develop a spirit of resilience. These are the characteristics of running sports.

Socks can be used to improve the leg muscles, and then it can also achieve the effect of forging and refining the leg muscles, which can improve the body's immunity, improve lung capacity, and improve the core lung function of filial piety. The audience is particularly large.
-
Running can promote blood circulation, can improve people's endurance, can also make people stronger, can also practice running, can effectively exercise the body, can also enhance the lung activity and volume.
-
You can strengthen your body, enhance your physique, and the investment is not high, you can exercise at any time, and you can train your ability to concentrate.

Cadence and stride length.
1. Cadence, that is, the frequency of footsteps, the number of times the legs alternate in a unit of time when walking or running. It is one of the important factors that determine the speed of walking and running. It is usually expressed in steps and seconds.
2. The stride length feature refers to the characteristics that reflect the coordination and collocation relationship of the two feet in the footprints, and is a form of reflection of the characteristics of walking movement in the footprints. Includes:
1) Step size. The vertical distance between the left and right footprints in the same part of the footprint is an ordinary step size. It can be divided into long steps (more than 80 cm), medium steps (70-80 cm), and short steps (less than 70 cm).
The left and right normal steps make up a single step. Three normal steps make up a compound step size.
2) Step width. In a continuous footprint, use a reciprocating line with the center point of the heel on the same side or the center point of the forefoot as the walking line.

1.Outdoor running has a lot of oxygen.
If you've experienced a side-by-side comparison of gym running and outdoor running, you'll definitely notice the fact that outdoor running is rich in oxygen. In addition, now that the spring flowers are blooming, there is not only a lot of oxygen in the air, but also the smell of grass and flowers. The breathing of indoor running is like a car with No. 93 gasoline, and outdoor running is with No. 97 gasoline.
2.Broaden your horizons.
Broaden your horizons, let your mood be relaxed in nature, and also be affected by the happy atmosphere around you. In addition, it speeds up blood circulation and allows waste products to be discharged through the pores, and the spirit at this time has also been improved to a certain extent. Exercise is also a stabilizer, once I did experiments, after physical education class, I went to the test to score better than the usual test results, and the mood is the best!
Therefore, many workers have to use travel to relax their mood every week! Life lies in movement, and movement makes people evergreen, this is a well-known truth. In particular, the "work bugs" (a term for some people who can only work and do not relax) who have lived in the city for a long time and white-collar workers who have been engaged in mental work for a long time are more meaningful.
3.Make mentors and friends.
Make mentors and friends, broaden your horizons, and enhance your popularity. Outdoor sports generally do not act alone, usually call friends and act collectively, this is for safety, you can take care of each other, and the second is because it increases the fun and makes outdoor activities not monotonous. Usually in outdoor activities, you can meet more new friends through the intersection of friends, exchange more biological shed work experience and work experience, broaden your horizons, and improve your popularity.
According to scientific research, a moderate amount of exercise is only good for the body, especially for modern people who have been under pressure for a long time, appropriate movement can not only reduce stress, relax muscles and bones, but also benefit the performance of daily work. Outdoor sports are a special kind of sports, which consume more physical strength and energy, and are a better way to strengthen the body.

First of all, the exercise intensity is very regrettable, and the effect of sweating can also be achieved during the exercise, which can enhance cardiopulmonary function, can breathe fresh air, and then has particularly high requirements for people's physical strength.
-
The characteristics of outdoor running are that we can breathe fresh air outdoors, and are not limited by the field of calling, when running outdoors, we must choose a relatively flat road, preferably some outdoor squares or playgrounds.
-
When running, you need to pay attention to safety, you need to do a good job of warm-up exercises in advance, and outdoor running should be more boring, which can better relieve emotions and can also exercise resilience.

We usually see a lot of people running outside, many people run in the morning, but there are also some people who run at night, now running has become a very fashionable and trendy way of exercise, everyone will run when they are fine, running can exercise everyone knows, so what kind of benefits should running such a sport, and how should it be done!
Anti-aging: The biggest benefit that running brings us is that it can be anti-aging, isn't there such a saying: life lies in sports, and the body of sports is a healthy body, resisting the acceleration of aging, and making yourself younger.
Release stress and eliminate burnout: Many people feel very tired, feel that they can't eat well and sleep well, but those who have running habits are different, they are energetic every day, they don't feel tired, and running for more than 30 minutes a day can effectively prevent tiredness and release pressure in life and work.
Anti-depression: Among the two options of medication and runners, the effect of running against depression is more obvious than taking medicine. Melancholy is caused by excessive pressure in life and work, which leads to brain confusion, and running can effectively sort out chaotic thoughts and reduce stress.
Prevention of breast cancer: Breast cancer is a common disease in women, and it is also a common disease in recent years, and the best way to fight breast cancer is to run, which can mobilize the operation of various organs and cells in the body, thereby reducing the possibility of cancer lesions.
Prevent osteoporosis: This is the most important for the elderly, the elderly because of the very serious loss of calcium, so it is easy to cause osteoporosis, to prevent osteoporosis in addition to eating calcium tablets, it is best to exercise more and bask in the sun. Running has a very good effect on osteoporosis!
In fact, in addition to these, running has many other benefits, the more common is to prevent diabetes and high blood pressure, lose weight, reduce body fat, and keep the body well-proportioned for a long time, but if you want to achieve these benefits, it is recommended that you should stick to it for a long time.
