Document Summary
Planes and axes: sagittal plane (left and right, running occurs in this plane, horizontal/transverse plane (upper and lower body, pelvis rotates in this plane, frontal (front and back) The spinal movements used predominately during running are. Left and right rotation as the spine mut rotate in the opposite direction of the hips in order to keep the body facing forward. Those with wobbly knees its mostly bc of the hips however the knee can rotate at end of ext. Cannot do the full range of motion of any of these without incorporating another. Better at change of direction = pronation (better for uneven surfaces/pliant) Better at straight line speed = supination (rigid) Action = flex the thigh and the rectus femoris is biarticular and also acts to extend the knee. Action = extend the hip and hamstrings (with the exception of the biceps femoris) are biarticular and also act to flex the knee.
