Motor skill refers to the automatic and perfect sports activity mode consolidated through practice. Such as writing, walking and cycling in daily life; Swimming, gymnastics and playing ball in sports; Activities such as sawing, planing and turning in productive labor are all motor skills.
Man's actions are composed of a series of actions. It is simply walking, and it is also the same activity as legs, feet, arms and eyes. Cycling is a joint activity of feet, legs, arms, whole body, vision and touch. At first, these movements were uncoordinated and clumsy. As a result of practice, the way to realize actions is consolidated, and some actions are liberated from consciousness and become automatic. At this time, getting on the bus, holding the handlebar, pedaling and other actions need not be considered, and they can be easily and flexibly realized one by one. However, automation is not completely unconscious. When activities encounter obstacles, people will consciously adjust their actions and remove obstacles. It can be seen that automation is the participation and control of consciousness to a small extent. The more automatic elements in motor skills, the more perfect the movements. The perfection and automation of motor skills is due to the establishment of a solid dynamic stereotype in the cerebral cortex. In the process of forming motor skills, the outside world often acts on the cerebral cortex in a certain order, thus forming the corresponding conditioned reflex system, that is, dynamic stereotype. All its links are arranged in a certain order, and as long as there is a start, it can cause a series of action reactions. But this conditioned reflex system is not fixed. When the situation changes, it will change accordingly. For example, when riding a bicycle, if a child intrudes on the road, he can avoid it tactfully. This shows that after mastering cycling skills, that is, after forming a dynamic stereotype, the cycling speed and direction can be adjusted with the change of conditions to adapt to the new situation.

What does a sports car mean?
The concept of sports car is relatively broad. Different from ordinary cars, sports cars strengthen the dynamic performance of vehicles and are obviously superior to ordinary cars in acceleration, steering, grip and handling performance. In addition, there will be differences in appearance, such as a more streamlined body and a small drag coefficient. The engine has stronger output power and greater torque. In addition to the comfort of mid-to high-end cars, sports cars should also have higher mobility and safety, and they should have a sense of movement, so as to publicize the young personality and the charm of the car.
The so-called sports car should be a broader concept, not a narrow niche product defined by professionals. Sports cars are not limited to functionality, such as racing cars or off-road vehicles, but also let more people experience the fun of driving. For example, an SUV is both a sport utility vehicle and a recreational vehicle. The development trend of modern automobile industry is "atypical" structure and mixed models, which blurs the boundaries of models that were originally easy to divide.
In fact, the sportiness of a car is not only a racing car, but also a civilian car with good handling performance can be called a sports car. Taking Saab as an example, the application of turbocharging technology and the adjustment of sports chassis can also make people enjoy the sports fun brought by strong power and excellent control during driving. In addition, Saab cars usually have a good aerodynamic shape, which also gives people a sense of movement visually and increases the ride comfort at high speed. The concept of sports car is subdivided to meet the demand of China's domestic automobile market. What needs to be distinguished is that a sports car is different from a sports car. It adds more sports design and adjustment to the family car. Compared with ordinary cars, sports cars should be better than other models in power and handling.

What do you mean exercise is absolute # # # # #
In physics teaching, we sometimes talk about the absoluteness of movement, and sometimes about the relativity or relative mobility of movement. So, is motion absolute or relative? Is there a contradiction here? In fact, these two statements are not contradictory, but they talk about different issues in different categories.
From the philosophical point of view, movement and matter are inseparable, and movement is the form of matter existence. Everything in the world is in an eternal state of motion, and there is nothing in nature except moving matter. Everything in the universe is moving endlessly. Therefore, when talking about the form of material existence in philosophy, it is said that movement is absolute. The movement mentioned here includes all changes, not just changes in position, which is the absolute meaning of movement.
In physics, when describing the mechanical motion of each specific object, we must first choose a reference object (frame of reference). When describing the motion of the same object, different conclusions will be drawn due to different reference objects. The relativity of motion is based on this fact.
To sum up, the absoluteness of movement is philosophical in terms of the form of material existence; The relativity of motion is based on the description of mechanical motion in physics.
What does the concept of sports mean?
Life and philosophy are in the fourth lesson.
Movement refers to the changes and processes of all things and phenomena in the universe.
Motion is the inherent property and existing mode of matter.
Movement is the movement of matter.
Movement is unconditional, eternal and absolute.
Static is conditional, temporary and relative.
A special state of motion at rest
Any substance is the unity of absolute motion and relative rest.
What does real exercise mean in psychology?
This is a concept relative to "similar motion". If you want to know the meaning of real sports, you must understand it in combination with similar sports.
I believe you know the concepts of "motion" and "static", so I won't explain them much. Whether the object we observe is moving or not is a process that needs our cognitive processing. In other words, there are two situations: the first is that the object is really moving, which is also the state of motion we observed. The second is that the object is not actually in motion. What we observe is that it is in motion. The former is called true motion and the latter is called quasi-motion.
The emergence of the second situation is determined by the physiological mechanism of our cognition. For example, the flicker frequency limit that human eyes can recognize is 15 frames per second. If a series of photos are presented to you at a speed exceeding this frequency, then you will see a dynamic picture, not a static photo (this is the principle of the earliest movies). Therefore, in order to study the seemingly moving movement in psychology, a relative concept: true movement is put forward.

What does aerobic exercise mean?
"Aerobic exercise" refers to moderate-intensity sports activities in which large muscle groups participate. Aerobic exercise can not only improve people's cardiopulmonary function, enhance endurance quality, but also consume excess fat in the body and control proper weight. Although all physical activities have health care functions, such as walking, boxing and other low-intensity physical activities; However, in order to improve endurance quality and enhance cardiopulmonary function, aerobic exercise must be carried out.
Aerobic exercise should be both intense and moderate. Generally speaking, the intensity of aerobic exercise must reach 75% of the maximum heart rate. However, it is difficult for most people to accurately measure their heart rate during exercise, so we recommend using "conscious power sharing method" to control exercise intensity. "Consciously exert oneself" literally means "self-feeling when exerting oneself". With the increase of physical activity intensity, people will gradually transition from "very relaxed" and "relatively relaxed" to "a little tired", "relatively tired" and even "very tired". The intensity of feeling "a little tired" during the activity has actually reached the requirement of aerobic exercise intensity. In other words, "aerobic exercise" means that people feel "a little tired" during activities. At this time, the exercise heart rate of normal people is about 70%-75% of the maximum heart rate.
In addition, the "heart-to-heart test" is also a way to prevent excessive exercise intensity. The so-called "heart-to-heart test" means that when doing aerobic exercise, if the exercise intensity is moderate, the exerciser can still talk with the surrounding companions. In short, "a little tired" and "heart-to-heart experiment" are both effective for mastering the amount of exercise moderately.
Representative aerobic exercises include jogging, swimming, aerobics, mountain climbing, Nordic walking, rope skipping, various ball games, brisk walking and so on. Young people had better do jogging exercise; Middle-aged and elderly people had better take "brisk walking" exercise. Because "fast walking" does not require special conditions and will not cause damage to bones and joints. When walking briskly, take a big step and follow the ground with your feet. This will produce a certain degree of mechanical action on bones, which has the characteristics of impact movement and has a good effect on strengthening bone strength and preventing osteoporosis.
The minimum requirements of aerobic exercise are: the cumulative time of daily exercise is not less than 30 minutes, and the number of exercises per week is not less than 3 times. Only by reaching such exercise time and frequency can we effectively enhance our endurance quality. It is difficult to improve people's endurance quality by exercising less than three times a week and less than 30 minutes a day.
