Abstract

high-step on a vertical indoor wall using different foot positions 1) with the inside edge of the foot or 2) with the front part of the shoe/toe against the wall. Subjects self-selected the rate of movement and specific body positioning, other than the right foot, during each trial. Reflective markers identified elbow, shoulder hip, knee, and ankle joints. Minimum and maximum joint angles were found via 3D kinematic analysis. With the exception of the elbow, Maximum joint angles were different between the two foot positions, however, there were no differences in the Minimal angles for any of the studied joints. Results indicate that when foot position is altered the climber adjusts maximum angles of other joints to perform the movement.
