315 Load Dynamics of the Joints on Nordic Walking with the change of the angle of inclination

Abstract

There are few studies focused on the various joint loads for NW. Therefore, as for examining having joint load reduction effect or not of the NW, it is with an important element judging the right or wrong of the application to everyday life of the NW for patients with joint disease and young people.The purpose of this study is to compare the joint load (lumbar spine, hip, knee and ankle joints) for NW to ordinary walking (OW) on a level surface and for going up and down hill. Standard 3D inverse dynamics was used to calculate joint force and joint moment in the lower limb joints. On level ground, NW had a load reduction effect on the hip compression and shear force, the knee compression and shear force, ankle shear force. Going up hill, NW had a load reduction effect on the hip compression force and knee shear force, ankle shear force. Going down hill, NW had a load reduction effect on the hip compression and shear force, the knee compression and shear force, ankle shear force.
