On the Concept of Resonance

Guest Post by Monica Lita

The resonance of an airplane in flight is analogous to the biomechanics of human movement, where joint interactions and compensatory mechanisms maintain functional stability. Just as the human body relies on interconnected joints to distribute forces efficiently, an aircraft’s structure responds to aerodynamic forces through its natural vibrational modes.

When external forces—such as turbulence or air currents—match the aircraft’s resonant frequencies, structural oscillations can amplify, much like how repeated mechanical stress on a joint can lead to compensatory movement patterns. In the human body, if one joint lacks mobility or stability, adjacent joints compensate, potentially leading to dysfunction or strain.

Similarly, in an aircraft, if specific structural components experience excessive vibration, other areas may absorb the load, affecting overall aerodynamic efficiency and structural integrity. The aircraft’s materials, design, and weight distribution dictate how these forces propagate, just as connective tissues, muscular control, and joint alignment shape human movement dynamics.

When wind is funneled toward an aircraft in a controlled manner, it mirrors how joint positioning directs tissue loading, ensuring predictable force transmission while minimizing compensations and energy loss. In both systems, maintaining controlled inputs allows for efficient force absorption and structural stability.

When no unpredictable forces act on the system, it operates in a state of low entropy, where stress distribution follows a structured pathway. In training and rehabilitation, precise joint positioning and controlled load vectors optimize adaptation from both a biological and neurological perspective.

As part of the Internal Isometric Loading Continuum at Absolute, we apply this principle by training tissues to develop reactive strength through Holding Isometric Muscle Actions (HIMAs) and Pressing Isometric Muscle Actions (PIMAs), directing force along predictable lines of contraction.
