Differences in physiological functions The physiological functions of the human body are a reflection of its internal morphological and structural integrity and coordination, and are a reflection of the functions of the internal organs and meridians and the essence, blood and fluid, and there are differences that reflect the bias in the functions of the internal organs, including human digestion, inhalation, blood circulation, fluid metabolism, growth and development, reproduction, sensory-motor, and spiritual consciousness. The body’s ability to prevent and resist disease, metabolism, self-regulation, and the basic state of excitement or inhibition all reflect the physiological function of the internal organs, meridians, and essence, blood, and fluid. Such as heart rate, heart rhythm, face color, lip color, pulse, tongue, whistling condition, language level, appetite, taste, body temperature, the likes and dislikes of hot and cold, the two stools, sexual function, reproductive function, women’s menstruation, the dynamics of the body and mobility, sleep, vision and hearing, touch and smell, the degree of pain tolerance, the elasticity of the skin and muscles, the amount and luster of the hair, etc., are all the same. The signs of physique are reflected by the components of physique. Therefore, when evaluating a person’s physical condition, it should be considered in terms of morphological structure, physiological function and psychological characteristics. 1, the evaluation indicators of physical fitness (1) the morphological structure of the body, including the body surface morphology, physique, body shape, internal structure and function of the integrity, coordination. (2) The functional level of the body, including the metabolism of the body and the function of the organs and systems, especially the cardiovascular and whistling systems. (3) The quality of the body and the level of motor ability, including speed, strength, endurance, sensitivity, coordination and the ability to walk, jump, run, throw, climb over and other basic physical activities. (4) The level of psychological development, including intelligence, emotion, behavior, perception, personality, character, will, etc. (5) Adaptability, including the ability to adapt to the natural environment, social environment and various mental and psychological environment and the resistance to disease, disease damage, regulation, repair ability. 2, the ideal health physique signs ideal physique is the human body in full play on the basis of genetic potential, after the active cultivation of the body’s morphological structure, physiological function, psychological state and the ability to adapt to the environment and other aspects of the overall development, in a relatively good state, that is, the state of unity of form and spirit. The unity of form and spirit is the sign of health, therefore, Chinese medicine often integrates the signs of ideal physique into the signs of health, and the signs of ideal physique also reflect the signs of health. The specific signs are: (1) good physical development, physical fitness, proportionate body shape, appropriate weight. (2) rosy complexion, eyes, hair, muscle skin elasticity. (3) A bright and strong voice, clean and strong teeth, intelligent ears, slow and even pulse, good sleep, and normal bowel movements. (4) Flexible movement, strong ability to exercise and work and other physical activities. (5) Energetic, emotionally optimistic, sensitive and strong-willed.
