Step 6 exercise strength
7. Exercise rhythm.
Body posture is an important factor in body movement. Body posture refers to the state of the body and various parts of the body at different stages of movement.
Trajectory refers to the spatial characteristics of the movement of a certain part of the body from the starting position to the end point. Motion trajectory is represented by motion trajectory direction, motion trajectory form and motion amplitude.
Exercise time refers to the time required for the human body to complete exercise, which is closely related to the speed and rhythm of exercise.
Motion speed refers to the displacement distance of the body or a part of the body in unit time. Motion speed represents the relationship between time and space in the process of completing an action, and reflects the comprehensive characteristics of motion time and space.
Motion rate refers to the number of repetitions of motion per unit time, also known as motion frequency. Motion rate shows the event process of motion and reflects the time characteristics of motion.
Exercise strength is the ability of the body or a part of the body to overcome resistance when completing exercise.
Exercise rhythm refers to the speed of exercise, the magnitude of exertion, and the reasonable alternation of muscle contraction, relaxation and time interval.
The concept of body movement 2 i. The meaning of movement
Motion is the fundamental attribute and mode of existence of matter, which includes all changes and processes in the universe.
Second, the relationship between matter and movement.
Matter and motion are inseparable;

Physical quality refers to the ability to successfully cope with the current or potential physical challenges in life, and it is a series of physical characteristics related to physical activities that people have learned or acquired. Among them, health-related physical qualities include cardiopulmonary endurance, muscle strength, endurance and flexibility, and body composition. At present, these physical concepts have been extended to indicators of metabolism, such as blood lipids and glucose tolerance. Physical quality components related to skills refer to flexibility, balance, coordination, speed, strength and reaction time.
