Knee-Ankle Joints Coordination Variability in Sedentary and Practitioners Young People at Different Speeds

EasyChair Preprint 11328

Abstract

The aim of the present study was to quantify the variability of joint coordination of the Knee-Ankle pair, during gait, of sed-entary and active young people at different speeds (preferred walking speed (PWS), 120% of PWS and 80% of PWS) using the Vector Coding technique. Thirty young people participated in this study, of which 15 practiced physical activity at least one hour a day and three times a week, and 15 were sedentary. To collect data from this joint pair, they performed a one-minute treadmill walking protocol at each speed, in a random order. Coordination was computed for four gait phases (first double support, single support, second double support and swing phase), in the sagittal plane. Data were analyzed using a custom Matlab code. There were statistical differences for the speed factor, with the greatest variability in 80% of the PWS, with predominant dominance of the ankle under the knee.
