Upper Body Motion In Running
Here in this article, we will shed light on the upper body motion in running. The movement in upper body while running is essential for maintaining balance along with a forward motion. They balance not only the motions of the lower body, but also keep the body in rotational balance. The leg's recovery is equaled by a forward drive of the opposite arm, while the leg's support and drive motions are stabilized by backward movement of the opposite arm. The shoulders and torso are also involved in the upper body movement in running.
The forward arm drive is seen to be more powerful and fast during the upper body motion while running. The more force put forth by the lower body, the more forceful are the upper body motions, so as to absorb the momentum. Although it is possible to go running without movements of the forearms, but the spine and shoulders will generally still be employed. Using arms helps to absorb the forces thus helping in maintaining balance at higher speed. Otherwise, there would be a fear of falling over.
Most of the energy spent in running goes to the balancing upper body motion in running. Therefore by getting rid of wasteful or incorrect motions, one can gain considerably in running speed as well as economy. For example, if the force vector in the drive stage is intended too far away from the centre of mass of the body, it will relocate at an angular momentum to the body which has to be absorbed.
Faster the running, the more energy has to be dispersed through compensating movement in upper body while running, and throughout the entire body. This is the reason why the world’ best sprinters have powerful and strong upper body physiques. It is seen that as the competitive distance increases, people competing at a high level in each respective event, show a rapid drop in the upper body and overall muscle mass. The long distance runners characteristically have lean muscles.
