Historical origin of physique
The concept of physical fitness originated in the United States, and the definition of physical fitness given by the President's Sports and Competitive Committee in the United States in 197 1 is generally accepted. It refers to the physical adaptability of individuals who are capable of enjoying leisure and coping with sudden changes and pressures.
The American Sports Medicine Association defines physical fitness as: "Physical fitness is the ability of the body to engage in daily work and leisure activities with vigorous energy, and calmly deal with unpredictable emergencies without excessive fatigue."
Although different countries and organizations have different written expressions of physical fitness, the core idea can be summarized as an adaptability of the body to life, exercise and environment. There is a common misunderstanding in the public's cognition of physical quality, and it is extremely wrong to think that physical quality is equal to physical quality, which will have a huge negative impact on teaching objectives and effects.
