Correlação da força vertical de reação do solo e da velocidade angular do joelho de jovens e idosas durante descida de escada

Abstract: Objetivo:Correlacionar a força vertical de reação do solo e da velocidade angular do joelho de jovens e idosas durante descida de escada.Métodos:A amostra foi dividida em dois grupos: Grupo Idosas (GI; n=10) e Grupo Jovens (GJ; n=16). Foi utilizada uma escada de teste composta por sete degraus, onde uma plataforma de força estava acoplada ao quarto degrau para aquisição dos dados cinéticos e determinação do momento de contato do pé com o degrau; também foi usado um sistema de cinemetria tridimensional, com qua… Show more

“…An additional difference between level walking and descending stairs is linked to the vertical ground reaction force (vGRF). Both tasks show two peaks in vGRF; however, during the step descent the first vertical peak is greater than the second peak [1], and although the horizontal forces are similar for braking impulse, the propulsive force is lower during step descent [1].…”

“…An initial assessment was conducted which included measures of body weight, height and Foot Posture Index (version 6) [1]. Lower limb kinematic data were then obtained using a 10-camera Oqus 7 system at 100 Hz (Qualisys Medical AB, Gothenburg, Sweden).…”
