1. Reduce air resistance: The posture of hunching the waist can make the runner's body more inclined and reduce the friction between the body and the air, thus reducing the resistance. This can improve running speed and running efficiency.
2. Improve the stability of the movement: The posture of hunching the waist can make the runner's center of gravity lean forward and increase stability. When running at high speed, maintaining a stable posture helps to reduce the waste of energy and allow runners to save more strength.
3. Support the core muscles: The posture of bow and waist can strengthen the support of the core muscles. Core muscles, including abdominal muscles, waist muscles and back muscles, are the key muscles to keep the body balanced and stable. Through the posture of bow and waist, we can strengthen the strength of core muscles and improve the stability and effect of running.
It should be noted that hunchback posture is not suitable for everyone. The running posture should be adjusted according to the individual's body shape, flexibility and technical level. Some people may need to maintain a more upright posture to reduce the burden on leg muscles, while others may need to adjust the angle of inclination to maintain balance. The most important thing is to find a posture that suits you, so as to maximize the running effect and reduce the risk of injury.
