Spirals are integral to asymmetrical movement, creating a dynamic interplay between spiraling up and spiraling down. These spirals reflect the body’s natural rotational patterns and allow for seamless transitions between loading and unloading phases in movement.


Spiral Up


• Associated with the unloading phase, where energy is transferred upward.
• Seen in the extension and elevation of the body, such as when the torso rises during a stride or when the swing leg is in motion.
• The movement starts from the ground, spiraling through the foot, up the leg, pelvis, and into the torso, creating an upward wave-like motion.
• Often linked to the “up side” or “high side” of the body’s asymmetry, facilitating lift, propulsion, or recovery.


Spiral Down


• Corresponds to the loading phase, where energy is absorbed and directed downward.
• Involves compression and grounding, such as when the stance leg absorbs impact during running or walking.
• The movement spirals down from the pelvis through the leg to the foot, grounding the body and preparing for the next movement cycle.
• Connected to the “down side” or “low side,” aiding in stability and force generation.


Spirals in Asymmetry


Spirals highlight the non-linear, multi-dimensional nature of asymmetrical movement:
• Left and right sides spiral in opposite yet complementary directions to maintain balance and enhance efficiency.
• These spirals create a natural rhythm, where one side may spiral down while the other spirals up, forming a continuous cycle.
• This interplay explains how asymmetry supports movement goals, with each spiral serving a specific functional role.


By embracing spirals as part of asymmetrical movement, the body leverages rotational dynamics to optimize force transmission, coordination, and adaptability in movement.
