Abstract
Abstract An athletic swing measurement method and apparatus for measuring characteristics of the swing of an athlete''s arm, bat or club. An accelerometer is provided for measuring acceleration or velocity and strain gages for measuring flex and twist of a plate placed on an athlete''s arm or within a bat or club, such as a golf club. Electrical signals analagous to the measurements of each gage are transmitted by a single transmitter to a receiver where they are converted for display, storage and comparison.
