Motor strategies and adiabatic invariants: The case of rhythmic motion in parabolic flights
N. Boulanger, F. Buisseret, V. Dehouck +2
The role of gravity in human motor control is at the same time obvious and difficult to isolate. It can be assessed by performing experiments in variable gravity. We propose that a…
Adiabatic invariants drive rhythmic human motion in variable gravity
N. Boulanger, F. Buisseret, V. Dehouck +2
Natural human movements are stereotyped. They minimise cost functions that include energy, a natural candidate from mechanical and physiological points of view. In time-changing en…
Higher-derivative harmonic oscillators: stability of classical dynamics and adiabatic invariants
Nicolas Boulanger, Fabien Buisseret, Frédéric Dierick +1
The status of classical stability in higher-derivative systems is still subject to discussions. In this note, we argue that, contrary to general belief, many higher-derivative syst…
Unstable Footwear as a Speed-Dependent Noise-Based Training Gear to Exercise Inverted Pendulum Motion During Walking
F. Dierick, A. -F. Bouche, M. Scohier +2
Previous research on unstable footwear has suggested that it may induce plantar mechanical noise during walking. The purpose of this study was to explore whether unstable footwear…
