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

The present study aimed quantify the variability of segmental coordination, during the gait of young practitioners and sedentary people on different slopes (Horizontal, 8% and 10% Upward (Up) and Downward (Down) conditions) maintaining the self-selected speed (VAS), using the Vector Coding technique. Thirty young people participated in this study, of which 15 were sedentary and 15 practiced physical exercises at least one hour a day, three times a week. They per- formed a protocol of walking 1 min on a treadmill on each inclination for data collection, in randomized order. For the Pelvis-Thigh segment, the angles were computed during the four phases of the gait (first double support, single support, second double support, and swing), in the sagittal Flat. The data were analyzed using a customized Matlab code, how had a normal distribution, an ANOVA was used to classify. There were significant statistical differences for the Simple Support and Swing phases, with greater variability for the slope situation.
