Anaerobic sprint ability is the key to improve running speed. In addition to the usual sprint training, it is also recommended to run with weight. For example, weight-bearing running such as sleigh running, resistance umbrella running and elastic belt sprint running is also a kind of strength training, which can be used as an auxiliary training for leg muscle exercise. This kind of training can improve the strength and nerve driving ability of hip and leg muscles, improve the recruitment ability and muscle control ability of sports units, and promote the secretion of hormones needed for muscle gain, thus achieving the effect of assisting muscle gain. This kind of training time should not be long, 6-8 groups, 15-30 meters sprint, the interval between groups is 2-3 minutes.

Of course, it should be noted that before the interval sprint training, you must be able to master the basic sprint skills. Sprint is divided into three stages: acceleration, maximum speed acquisition and maximum speed maintenance. These three stages have different skill requirements.

Acceleration stage-get the maximum speed in the shortest time. The best acceleration posture can be illustrated by a picture: the legs and trunk are in a straight line, which is about 45 degrees from the ground; The front legs are parallel to the rear legs, and the instep is slightly hooked; Swing back and forth completely Remember: the best way to accelerate is to put the center of gravity forward, and then scrape it back to chase the center of gravity.
