Quantification of Gait Coordination Variability of Pelvis-Thigh Segments in Young Sedentary and Practitioners People Walking in Different Slopes Using the Vector Coding Technique

EasyChair Preprint 4547

Abstract

The aim of the present study was to quantify the variability of segmental coordination, during the gait of young practitioners and sedentary people on different slopes (Horizon-tal, 8% and 10% Upward (Up) and Downward (Down) condi-tions) maintaining the self-selected speed (VAS), using the Vec-tor Coding technique. Thirty young people participated in this study, of which 15 were sedentary and 15 practiced physical ex-ercises at least one hour a day, three times a week. They per-formed a protocol of walking 1 minute on a treadmill on each inclination for data collection, in a randomized order. For the Pelvis-Thigh segment, the angles were computed during the four phases of the gait (first double support, single support, sec-ond double support and Swing), in the sagittal plane. The data were analyzed using a customized Matlab code. There were sig-nificant statistical differences for the Simple Support and Swing phases, with greater variability for the slope situation.
