Why full-body coordination matters for running stability
Runners who consciously engaged their arms in proper swing patterns had reduced torso angular motion around the spine's longitudinal axis — meaning less torsional stress through hips, pelvis, and spine.
This reduction in torso rotation improves overall movement efficiency and energy use, translating to less joint wear-and-tear, lower compensatory strain, and improved posture over time.
The findings support a full-body, integrated movement approach rather than isolating muscles. Coordinating arm-leg-torso patterns significantly influences spinal and lower-body load distribution.
Many rehab protocols overlook arm swing and upper-body coordination when treating lower-body issues. This research shows neglecting upper-body movement perpetuates torsional and alignment stress.
