​Importance of Arm action to improve running performance and speed

The role of the arms is to stabilize the torso so that power can continue to be efficiently transferred through the hips. It is this ability to transfer power effectively through the center of mass that not only improves rate of acceleration, but also facilitates reaching maximum velocity, maintaining those top speeds and reducing the rate of deceleration.

The front arm angle should be between 60-90 degrees at the elbow and your back arm should be between 90-120 degrees, also at the elbow. If your arm angles fall outside of this range, your running mechanics will be negatively affected. In short, you'll run slower and get tired faster. When running, arm swing should be initiated at and through the shoulders. You should think of your elbow as being locked in place.

Elbow angle should only change slightly, as a result of elastic response. Range of motion with the arms should generally be hip to cheek. That is, the hand clears the hip in the back and comes up to about cheek height in front. Much more than that, in either direction, will result in over striding which, as mentioned before, will cause breaking and can lead to strains, pulls and tears in the muscle.
