The difference is that physical fitness is generally more focused on the development of various sports physical fitness; Physical fitness coverage is the overall level of health of the body (e.g., body shape and composition, muscle strength, cardiorespiratory fitness, joint flexibility, skills and functions required for life and work, etc.).

The concept of physical fitness originated in the United States and was proposed in 1987 by the health, physical education, and dance organizations of the American sports community.

Its main core content is to improve children's aerobic fitness, muscle strength and endurance, flexibility, body composition knowledge and methods, as well as nutrition and physical activity health knowledge through physical activity.

The World Health Organization defines "physical fitness" as the ability to have enough energy and stamina to carry out daily tasks without excessive tiredness, and to have enough energy to enjoy leisure activities and cope with emergencies.

The five main measures of fitness include cardiorespiratory endurance, muscle strength and endurance, body composition, flexibility, and neuromuscular relaxation.

Physical fitness is divided into healthy physical fitness, competitive physical fitness, and metabolic physical fitness.

Healthy physical fitness: Physical fitness, which is closely related to health, is the basis for the body to maintain its own health, and is the premise for the body to maintain a happy daily work and reduce the occurrence of chronic diseases.

Physical fitness refers to the ability of various parts or systems of the body to respond to unexpected situations, including a wide range of such as speed, reaction, endurance, muscle strength, balance, flexibility, coordination and agility.

Occupational physical fitness is the physical fitness related to occupation (labor) and the tolerance and adaptability to adverse working environmental conditions, and the physical activity ability required after specific work ability analysis, including repetitive operation ability, the ability of back muscles to bear static force, the ability of other muscle groups to meet the requirements of maintaining work posture, and the ability of the human body to tolerate the working environment.

The importance and necessity of practical physical training.

The main goal of higher vocational colleges is to cultivate practical and high-skilled talents needed by the country. The professional positions that students engage in after graduation objectively put forward different requirements for their physical fitness, and they have to adapt to the intense and monotonous assembly work.

It must withstand the interference of mechanical oscillation and noise; It must withstand the invasion of special odors and high temperature and strong cold; It is necessary to be able to complete high-precision production tasks in high, difficult and dangerous environments, and so on. This requires future higher vocational talents not only to have high vocational and technical operation ability, but also to have strong physical fitness, showing strength, endurance, speed, sensitivity and other physical qualities closely related to vocational technology.

Physical fitness generally refers to occupational physical fitness. Physical fitness, also known as physical fitness, refers to the ability of various parts or systems of the body to respond to unexpected situations, including a wide range of speed, reaction, endurance, muscle strength, balance, flexibility, coordination and agility.

Occupational physical fitness is the physical fitness related to occupation (labor) and the tolerance and adaptability to adverse working environmental conditions, and the physical activity ability required after specific work ability analysis, including repetitive operation ability, the ability of back muscles to bear static force, the ability of other muscle groups to meet the requirements of maintaining work posture, and the ability of the human body to tolerate the working environment.

On the one hand, the physical education of higher vocational colleges has the common characteristics of ordinary college sports, that is, it is necessary to complete the task of enhancing students' physical fitness, improving students' physical fitness, and cultivating good quality and healthy psychological behaviors and habits; On the other hand, the training objectives of higher vocational colleges are different from those of ordinary colleges and universities, and their education and teaching have the characteristics of orientation, practical operation and professionalism, so the sports of higher vocational colleges have their individuality, that is, they should serve the characteristics of the profession. It is a new topic for higher vocational colleges to fully understand the relationship between physical education and vocational education, so that higher vocational colleges can appropriately carry out vocational physical training on the basis of completing the content of general general education, promote the improvement of students' vocational skills and physical fitness, and better reflect the characteristics of physical education in higher vocational colleges.

To put it simply, the body stores the amount of glycogen it consumes on its own based on recent physical exertion. If you exercise every day, then the body will adjust to a metabolic state with a certain exercise capacity, that is, high physical fitness; On the contrary, if you do not exercise for a long time, then the basal metabolism will decline, and the cardiopulmonary function does not need to maintain the original intensity, and the physical fitness will be low. Physical fitness is the standard of physical health, and good physical fitness naturally leads to a good body.

Physical fitness is defined as the body's adaptation to life, movement and environment (e.g.; temperature, climate change, or viruses). People with better physical fitness have better vitality and adaptability in daily life or work, engaging in physical activities or sports, and will not easily feel tired or exhausted. In a civilized society with scientific and technological progress, human beings have fewer and fewer opportunities for physical activity, higher and higher nutritional intake, and the pressure of work and life and leisure time are relatively increasing, and everyone feels the importance of good physical fitness and regular exercise.

Physical fitness focuses on the athletic ability of competitive sports, and physical fitness in the narrow sense refers to the athletic ability of the human body acquired in order to achieve a certain level of competition. From the perspective of health, physical fitness refers to the functional ability of the body to handle daily work normally and have spare energy to enjoy life and deal with emergencies, which is divided into healthy physical fitness and skill physical fitness.

The main contents of healthy physical fitness are as follows:

Body composition: that is, the percentage of various components in the human body, and maintaining body composition in a normal percentage range is important for the prevention of certain chronic diseases such as diabetes, hypertension, arteriosclerosis, etc.

Muscle strength and muscular endurance: muscle strength is the maximum force that a muscle can produce, and muscular endurance is the ability of a muscle to contract continuously, which is the basis for the normal functioning of the body.

Cardiorespiratory endurance: Also known as aerobic endurance, it is the foundation of the body's long-term work and is considered the most important element of healthy physical fitness.

Flexibility: refers to the maximum range of motion that a joint can move without pain. It is of great significance for maintaining the body's ability to exercise and preventing sports injuries.

Physical fitness exercises help to strengthen muscles, and by the end of puberty (16 years for women and 18 years for men), the rate of muscular endurance growth in both boys and girls slows down. Therefore, children and adolescents should actively engage in sports related to the enhancement of muscular endurance during mid-puberty.

In addition to this, physical fitness exercises also have a positive impact on physiology, respiratory system, nervous, endocrine and immune function.

Children's amusement projects are pure play, and children's physical fitness is guided by science, grasping the child's sports sensitive period, and comprehensively developing the child's strength, speed, agility, balance, coordination and other abilities.
