This paper aimed to figure out knee altered kinematics and to investigate possibility of knee injury in middle aged males when performing walking and running. Twelve healthy middle aged males 45 60 years volunteered to perform walking 3 km h and running 5 km h on treadmill in the biomechanics laboratory. A set of markers were attached to specify knee landmarks of each participant, who was tracked by a 7 cameras 3D motion capture system. The marker positions were used to determine the segment coordinate system SCS for calculation of knee flexion, as well as abnormal kinematics included knee internal rotation, varus rotation and anteroposterior translation. The result showed similarity of knee altered kinematics during walking and running. The maximum of knee flexion, internal rotation and varus rotation of running were higher than walking significantly, whereas there was no significant difference inanteroposterior translation p 0.05 .The repetitive anteroposterior translation could increase the risk of knee injury, while increased varus and internal rotation have been associated with the progression of iliotibial friction syndrome. This study provides the information that middle aged males runners can use to develop running techniques.
