“…Affordances in postural control depend on constraints defined by the environment, the task, and the organism's properties (Bardy, Marin, Stoffregen, & Bootsma, 1999;. With regard to these three types of constraint, researchers have addressed the question of how the organism's properties influence postural control by studying the effects of biomechanical parameters (Bardy et al) and aging or pathologies (Bronstein & Guerraz, 1999;Horak, 2006;Sparrow & Tirosh, 2005). Researchers have also explored the question from a developmental perspective (Lejeune et al, 2006) and by the investigation of the intense motor experience created, for example, by sports practice.…”
