Middle-aged, eight-character step
Old age, step by step.
Adolescents have great physical strength, less fat, large muscle content and a lot of muscle support. People have good coordination in jumping, running, endurance, health, fitness and bodybuilding. At this time, the human body is at its peak, and the pace at the peak is the most magnificent and powerful, so it is a straight line.
When people reach middle age, their muscle content is low, their fat is high, their endurance is gone, and they can't jump or run fast. Fat is mainly distributed in the abdomen, thighs and buttocks. If you have more fat, your center of gravity will move backwards. At this time, people like to stand with a big belly and take small eight-step steps.
When people are old, their knees are badly worn and their ligaments are aging. At this time, people's legs will slowly expand outward from their knees and gradually become O-shaped legs, which will inevitably bring steps.
The change of pace is the embodiment of different stages of life.
