The Effect of Cross-Sloped Surfaces on Running Kinematics

Abstract The purpose of this study was to analyze the effect of cross-sloped surfaces on the kinematics of recreational female runners. Eleven recreational female runners (20.2 ±1.2 years, 59.8 ± 8.6 kg, 1.65 ± 0.04 m) volunteered to run on a treadmill at a moderate pace of 3.35 m/s in three conditions: level (L), 5⁰ lateral elevation (LE), and 5⁰ medial elevation (ME). Each participant ran in the same model of neutral shoes with a window cut out of the heel to allow for two calcaneal markers to be placed directly on the skin. Joint angles were recorded for two strides in each condition from the rear and the side view using two Sentech cameras (100 frames/second) and then digitized manually. A repeated measures ANOVA (
