JOINT LOADING OF LOWER EXTREMITIES DURING NORDIC WALKING COMPARED TO WALKING BASED ON KINETIC AND KINEMATIC DATA

Abstract

Based on a higher cardio-pulmonary and cardio-vascular benefit and a promised reduction of mechanical load of the musculoskeletal system Nordic Walking (NW) shows an increased market potential. The present study should investigate whether there are differences in joint loading of lower extremities using an inverse dynamics approach between NW and Walking. In this experiment 15 subjects participated, who were already experienced with the NW technique. Kinematic data were collected using a 6-camera 3-dimensional Vicon System. Kinetic data were recorded using a Kistler force plate. Based on the findings it is to summarize, that the use of the poles during NW, performing the diagonal technique, do not lead to a reduction of joint loading of the lower extremities compared to Walking in general. Moreover for NW a higher knee joint loading during landing could be observed which is caused by the specific NW technique.
