Comparison of Different Body Postures during Running on Peak Knee and Hip Mechanics

The purpose of the study was to determine whether increasing trunk flexion (TF) and whole body inclination (WBI) angles influences peak knee, hip, and trunk kinematics and kinetics during running. Nineteen participants ran over ground at a self-selected speed under three postures: self-selected normal (SSN), TF, and WBI. Analyses revealed significant differences between conditions for peak knee, hip, and trunk flexion angles and peak knee and hip extension moments. Both TF and WBI postures are effective strategies for reducing peak knee extension moments during running with more load distributed to the hips. This may reduce PFJ stress and therefore aid in knee injury prevention and management. Individual preference of either altered running posture should be utilized in a clinical setting.
