The potential for injury is present in all forms of physical activity, particularly events involving repetitive motion. In attempt to identify kinematic changes following running induced reductions in muscular strength, 15 participants completed recorded treadmill runs before and after an outdoor run. Kinematics were recorded using a Vicon motion capture system and processed using 3D GAIT custom software. Using repeated measures ANCOVA with side (dominant and non-dominant) and time (pre-run and post-run) as within subject factors, and strength and arch height as covariates, no statistically significant differences were obtained. Using Pearson’s product-moment correlation coefficients to compare successive strides, post-run reductions in stride-to-stride correlation were obtained for dominant and non-dominant knees. Further, MANOVA analysis using standard deviation values corresponding to thirds of stance phase suggested that dominant and non-dominant ankle, as well as dominant knee frontal plane movements became more variable following the run, primarily during the initial third of stance.
