Speed quality is the distance the human body moves in unit time or the ability to respond to external stimuli;
Strength quality is the strength produced when some muscles of the body contract;
Endurance quality refers to the ability of human body to carry out muscle activities and resist fatigue for a long time;
Sensitive quality refers to the ability to quickly change posture, change movements and improvise;
Flexibility refers to the elasticity and extensibility of muscles and ligaments of various joints during human activities.
Features:
Strength quality
From the perspective of strength quality, the development of strength and strength endurance of lower limbs and upper limbs of adults and elderly people of different ages in China has its own characteristics. The strength of lower limbs (20-39 years old) shows a continuous downward trend with the increase of age, and the decline rate is slightly greater in men than in women; The south is superior to the north; Urban non-manual workers are better than urban manual workers and farmers.
The strength of upper limbs shows that the grip strength of adults continues to increase before the age of 35, and then decreases with age. The sustained development time of female upper limb strength is longer than that of male, and the growth rate is faster than that of male. The decline curve is synchronous, but the decline speed is lower than that of men.
The grip of northerners is better than that of southerners; Urban non-manual workers
Speed and Sensitive Quality From the point of speed and sensitive quality, the development characteristics of speed and sensitive quality of adults and the elderly in China are that with the growth of age, both men and women show a downward trend, and the downward trend shows that men are slow first and then fast, while women are the opposite. The numerical characteristics of gay and lesbian age groups are that men are better than women. The general trend of the speed and agility of adults in China is that the south is superior to the north.
The general characteristics of speed and sensitivity of men and women of all ages are: urban non-manual workers are better than urban manual workers, and urban manual workers are better than farmers. Judging from the changing trend of balance ability, the balance ability of adults and the elderly at all ages in China shows a continuous downward trend with the growth of age.
The quantitative characteristics of the balance ability of men and women in the same age group are that men are better than women, and there is a significant difference between the ages of 35 to 39 and above. The balance ability of adults and the elderly in China is obviously different between the north and the south, and the south is better than the north.
The balance ability of different types of adults in China is as follows: urban non-manual workers
Flexible mass
From the perspective of flexibility quality, the characteristics of flexibility quality of adults and the elderly in China are as follows: at the age of 20-24, the forward flexion of both men and women is between 1 1- 12 cm, and the forward flexion of both men and women decreases with age; However, the decline rate of women is lower than that of men.
The flexibility of adults and the elderly in China is better than that in the south, with significant differences. The characteristics of flexible work at all ages are that farmers are the best.
Other understandings
Under the background of quality education, according to the development of the times and the requirements of practice, physical quality should be defined as the physiological condition and comprehensive and relatively stable quality or ability of the human body under the joint action of congenital factors and acquired factors.
Congenital factors mainly refer to genetic factors, which provide preconditions for the formation and development of physique; Acquired factors mainly include nutritional status, medical conditions, climate and environment, living habits and exercise. That is to say, besides the traditional elements, physical quality should also include the body's adaptability, adaptability and ability to resist emergencies.
The adaptability of human body is manifested in its adaptation to the natural environment and its resistance to diseases. Long-term exercise in various climatic and environmental conditions can improve the body's temperature regulation function, thus improving the body's adaptability to the natural environment.
At the same time, various physical exercises can promote blood circulation, strengthen metabolism and improve hematopoietic function, thus improving the body's resistance and immunity to viruses and germs and effectively preventing various diseases including "civilized diseases".
Resilience refers to people's ability to cope with emergencies and emergencies, or how to respond appropriately at the fastest speed when the external environment changes.
Emergency handling capacity refers to the handling capacity of any event that needs immediate handling, endangers national security, public safety and social order, threatens the safety of citizens' lives and property, and may cause serious consequences.
