Stable, Unstable and Metastable States of Equilibrium: Definitions and Applications to Human Movement
Bibliographic record
Abstract
Human postural demands and balance control during locomotive and rotational motion are of primary interest for athletic performance and daily life. The equivocal use of terms and expressions such as equilibrium, balance, stability/instability obstruct a clear communication of scientific knowledge. In particular, the terms stability and balance and their different forms or word combinations are often used with various meanings and circular definitions not only in everyday language but in scientific communication as well. Further, stability and balance issues of human movement are often inadequately discussed in the literature in the form of equilibrium situations of rigid bodies. However, for animate systems, stable and unstable equilibrium approaches are too simplistic. As an alternative, the ‘metastability’ concept predominantly used as part of the dynamic systems theory should be applied to human movement. \n \nThus, the objectives of this letter to the editor are to define established and frequently used terms that describe responses to human movement behavior and to introduce and rationalize the use of a more appropriate and encompassing term entitled ‘metastability’.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
