1. A method for calibrating and using a load configuration for a sports implement or an anatomical feature, said method comprising the steps of:
a.) collecting data corresponding to positions and orientations of said sports implement or anatomical movement of said subject relative to a known position and orientation of said sports implement or anatomical movement of said subject, said data being collected over the movement of said sports implement or the anatomical movement of a subject during their use of said sports implement;
b.) calibrating a load configuration for the sports implement or anatomical movement by searching data of said collecting step and identifying data that corresponds to a selected rate of movement of said sports implement or a selected rate of anatomical movement of said subject that is consistent for repeated motions of said sports implement or said anatomical movement of said subject; and
c.) using said load configuration to analyze the position and orientation of the sports implement or the anatomical movement of said subject that occur subsequent to or prior to or both subsequent to and prior to said load configuration.
