title: A study of the Achilles tendon while running.
abstract: The following study attempts to elaborate a model of the Achilles tendon while in the process of running, specifically during a step that is part of a running sequence. Data are collected with the help of a force plate and then is processed and modeled to serve as a starting point and comparison to a mathematical model using polynomial functions. The data collected were filtered to diminish recording of "noise" and an empirical model was established. Mathematical models using second order and fourth order polynomials were employed, as well as an approximation using known maximal force. The increase in the accuracy of modeling was determined as the order of the polynomial function increased. Achieving an accurate predictor function is essential in understanding the biomechanics of the Achilles tendon.
