Dashing is a movement of ultimate strength that requires people to reach their finish at the highest speed, maximum intensity, and shortest time in the absence of oxygen in the body’s organs of motion. This requires not only good physical fitness and strong will quality, but more importantly, the rational use of technology and the ability to relax with the whole body. Physiologically speaking, the strength of muscle originates from the resultant contraction of various muscle groups during exercise, and whether or not each muscle group is coordinated directly affects the speed of muscle contraction and displacement, so that muscle
