Single leg dynamic and static legpress exercise with a robotic training device

This project contains the data of 13 human subjects performing static and dynamic leg press exercises on a robotic leg press training device. All trials were performed at a force level representing the 60% MVC force (recorded in initial position), which was monitored through a visual feedback showing the prerecorded MVC and the 60% MVC levels.<br>The initial exercise position for each participant was set by placing the robot-mounted force plate to obtain 80° hip joint flexion, 50° knee joint flexion, and 0° at the ankle joint.Participants performed static trials in three different positions: in the initial position (neutral) and altered initial positions with 12° eversion (lat) and 12° inversion (med) of the ankle joint.Participants performed dynamic trials at a constant velocity of 0.025 m/s on a linear trajectory. The trajectory was set to induce a range from 80° to 40° knee flexion angle. Data was normalized to the movement trajectory from 0% to 100%.Data recorded were: Forces and moments applied to the force plate mounted at the endeffector of the robotic training device @ 2000 Hz, 3D Motion capture of the right leg and pelvis @ 100 Hz.<br>Data are stored in *.csv files. Participants were named by consecutive numbering from 1 to 13.
