The Long & Short of it.
Proper warm up, systematic velocity and technique training AKA Tempo, timing  & execution.
Most athletic moves are not completed by the individual.  If they had just followed through with the task at hand, whether it  be the baseball/softball throwing motion, swinging  a bat,  swinging a golf club or  tennis racket. That last split second of effort can complete the athletic move at hand successfully. With an increasing focus to address youth sports injuries due to improper warm up and training the Accraspeed  is paramount as a sports training aid.

The Accraspeed can be worn like a wrist watch.  Casing is made of high impact aluminium therefore is very durable for all applications, light weight and can be made in different colors.

Through the multi settings ability of the Accraspeed, one may start at warm up level which will give the audio feedback of a completed motion of the athletic move at hand. After warming up and moving toward increase speed, one may bump up the level and listen for the tone indicating the athletic move at hand is being completed fully. One may monitor daily, monthly and yearly progress.

The Accraspeed registers outward centrifugal force effort. Which is a predominant neccesary  force in a lot of  popular sports worldwide. Is simple to use with immediate feedback to technique and effort.
