Abstract

This thesis had two goals; 1) the development of an anatomically accurate visualization tool capable of illustrating high-speed 3D kinematic data, and 2) to rigorously evaluate the accuracy and capacity of the visualization tool by measuring the joint moments, net extensor muscle forces, and effective mechanical advantage in a group of sprinters running across the range of human speeds. Our visualization tool successfully integrates these complexities, pinpointing a location within 1.3 mm in a volume of 0.87 m x 2.00 m x 1.98 m, and accurately reproduces the observed movement trajectories of the subject's anatomical landmarks. Our approach was successful in yielding similar joint moments and gait spatiotemporal parameters found in other studies, supporting the reliability and accuracy of our system. This visualization tool distinguishes itself from existing tools in its capacity to not only depict but also critically evaluate this alignment between high-speed kinematics and kinetic data, providing an exclusive opportunity to examine the extent to which the measurements produced by the platform correspond to real-world results in a way that no other platform allows.
