Abstract
Abstract A high-speed, portable computer interfaced, fluid-filled, foam-padded, heavy bag with local electronic force indicator is provided along with a mechanically-driven paper chart recorder with digital output, split screen video data recording system, and printer for automatic data analysis used to measure a fighter's individual, peak, and total applied force on a target. Such target is constructed so that the fighter feels both familiar and comfortable for each hit, each session, and for such fighter's entire training career spent practicing a bag connected in the system of the present invention. Such system is accurate enough to determine at which point a fighter'punching or kicking muscle groups undergo initial fatigue and subsequent tetanus, or tightening.

Claim 1
Independent Claim
272 words
A system for measuring and recording total applied force instead of only peak force associated with martial and boxing arts, said system including in combination bag means vertically supported at the upper end and including a transducer, interface means connected to said transducer, recorder means providing a recording and connected to said interface means, computer means including program means connected to said recorder means, said computer means being comprised of standard components not requiring customizing, dot matrix printer means connected to said computer means for providing the compared results from the computer means, wherein said results including the total applied force instead of only the peak force for an entire training session, number of strikes, force of each strike, average force per strike, average strikes per minute, maximum and minimum force strikes and when such strikes occurred, fastest and slowest time between two strikes, and the time when the average force per strike starts to decline rapidly to indicate fatigue of the muscles used to strike said bag means so that progress of training may be ascertained, first and second video cameras, said first video camera being focused on said bag means and said second video camera being focused on said recorder means, video data processor means connected to said first and second video cameras, video cassette recorder means connected to said video data processor means, and video data monitor means connected to said video cassette recorder means whereby said bag means and the person applying a plurality of intermittent strikes to said bag means is displayed in synchronization alongside the total applied force from each of said plurality of intermittent strikes.
