What kinds of physical qualities do you usually refer to? How do college students develop various physical qualities?
Physical quality, referred to as physique, is the basis of quality of life. Specifically, it includes the following contents:

① Strength: an external manifestation of human body's work, which is the ability of muscle tension or contraction. It is the most important functional quality for human life, work and life maintenance.

② Speed: It shows the speed of a person's movements, which is an ability of the human body to move quickly. It can make the heart rate reach the physiological limit and stimulate the human nervous system the most.

Endurance: the endurance of human physical strength and cardiopulmonary function for as long as possible. It can also be regarded as the anti-fatigue ability of human body. Endurance should be a combination of whole body endurance, muscle endurance and cardiopulmonary endurance.

④ Flexibility: It is determined by the bone structure of the joint, the volume of tissues around the joint, and the extensibility of ligaments, tendons, muscles and skin of the hip joint. Flexibility can directly affect the coordination, range of motion and flexibility of limbs.

⑤ Sensitivity: In an unexpected situation, when the body position changes rapidly, it can show the comprehensive performance of various skills and qualities.

The strength of physical fitness is one of the important signs to measure a person's physical condition. The development of physique is of great significance to enhance people's physique and health, master sports skills, improve sports performance and realize the purpose of physical education and health teaching in colleges and universities. The university stage is an important period to promote the development of various physical qualities, especially strength and endurance. If we miss the opportunity, we will spend more energy on compensation. Therefore, it is of far-reaching significance for college students' physical and mental health to seize the opportunity and carry out comprehensive physical fitness activities.

(A) the way to develop the quality of strength

Strength quality refers to the ability of muscle contraction to overcome resistance and resist resistance, which is one of the basic qualities of human body and the basis of various sports.

Developing strength quality can not only enhance muscle strength, improve physical strength, make the body stronger, fuller, more symmetrical and bodybuilding, but also help to learn and master various sports techniques and skills and reduce sports injuries.

The university stage is a period of rapid development of strength and quality. It is necessary to focus on improving the muscle strength of upper and lower limbs, chest and back, waist and abdomen, promoting the balanced development of the body and changing the shape of "bean sprouts".

1. The changing factors of developing strength quality exercises

The practice method of strength quality consists of some basic elements. By mastering these elements and their laws, we can create and design various strength training methods according to the needs of exercise.

2. To develop strength quality, we should pay attention to the reasonable arrangement of exercise load.

(B) methods of developing endurance quality

Endurance quality refers to the ability of human body to resist fatigue when doing muscle activities for a long time. Endurance quality is a comprehensive expression of the function and psychological quality of human organ system, and also an important symbol of human physical strength. Developing endurance quality can effectively improve the function of human respiratory system and cardiovascular system, improve metabolism level, enhance anti-fatigue ability and cultivate excellent psychological qualities such as perseverance and perseverance.

The university stage is a period of rapid development of endurance quality, and the development of endurance quality is also the key content in physical education and health teaching. Senior high school students mainly develop aerobic endurance and anaerobic endurance.

The changing elements of training methods to develop endurance quality (12 minutes running)

12-minute running is a popular exercise mode in the world, which has a good effect on developing aerobic endurance and improving cardiovascular function. Introduce the method of 12 minute running;

After running 12 minutes, you can know your aerobic metabolism level by looking at the score sheet according to your running distance.

(C) methods of developing speed quality

Speed quality refers to the ability of human body to move quickly. The response ability of the nervous system, the frequency and the range of actions are the main factors that affect the development of speed quality.

Developing speed quality plays an important role in improving the ability of cerebral cortex to react quickly, command and coordinate the body, and making the body more flexible and move faster.

The speed quality of college students still has great development potential, so we should seize the opportunity to promote its development.

Methods of cultivating sensitive quality

Sensitive quality refers to the ability of people to change their body movements quickly, accurately and harmoniously under various sudden changes.

Developing sensitive quality plays a very good role in improving the flexibility of cerebral cortex, making some corresponding actions quickly, accurately and harmoniously under changing circumstances, cultivating good observation, judgment and reaction speed, and promoting the development of other qualities.

Changing factors of developing sensitive quality practice methods

Refer to the change chart of fast running.

Ways to develop flexibility

Flexibility refers to the range of joint activities and the extensibility and elasticity of soft tissues such as muscles and ligaments.

Developing flexibility is conducive to correctly mastering various sports techniques and avoiding damaging soft tissues such as muscles and ligaments under sudden exertion.

The flexible quality of college students has certain development potential, so we should strengthen exercise and promote its development.

Changing factors of developing flexible quality practice methods

1. The development level of physical quality is one of the important signs to measure people's physical condition. All-round development of physical fitness is of great significance to improve senior high school students' physical fitness, master sports skills and improve sports ability.

Second, the university stage is a favorable period for the development of physical quality. We should seize the opportunity, learn from each other's strengths and pay attention to the development of aerobic endurance and strength quality on the basis of comprehensive exercise.

Thirdly, the methods of fitness exercises have their own rules, and mastering the rules can create a variety of methods suitable for self-exercise.

Fourth, it is conducive to observing the basic laws of physical exercise, step by step, and always adhere to it.

2. According to the changing factors of developing physical fitness practice methods, create some methods to develop physical fitness according to your own situation and enrich your exercise prescription.

Mutual transfer of physical quality

The physical quality of human body does not exist and develop in isolation, but there is migration between them. The mutual transfer of physical qualities is called the influence of the development of one quality on the development of another. For example, the improvement of strength and speed can improve the quality of speed accordingly; The improvement of general endurance quality indirectly promotes the improvement of speed endurance quality; All physical qualities depend on the overall level of various organs and system functions, and provide conditions for the development of quality, and the improvement of quality can promote the development of physical functions. Therefore, the all-round development of various physical qualities is very important to improve health.
