Abstract: We are living in a smart world. In This technical era, each and every field was automated by electronic implements with extreme precise, which were tireless to bring out our grit successfully. The present investigator has crafted an electronic gadget to assess the Acceleration and Deceleration Phase of Sprinting Event. These are the most important phases in sprinting event, these segments performance are the fortitude of sprinting event. Presently acceleration and deceleration skills are not assessing in most of sprint event like district, divisional and state level events due to lack of appropriate devices. The influence of acceleration and deceleration proficiency of the athlete is high on the result of every sprinting event; in this phases quick acceleration and delayed deceleration ability will lead to high performance, hence this is a vital part of every sprinting event. This has leaded the investigator to craft an electronic device to find out accurate acceleration and deceleration ability of sprinters. The device contained some fundamental parts as1.Microphone 2.Infrared Transmitters, 3.Infrared Receivers4.Interfacing Unit and Computer. The outcome of each and every innovations should have scientific authenticity which is also indispensible at any circumstances. To attain the scientific authenticity of the device, 120 subjects were chosen from Hindusthan College of Engineering and Technology, Coimbatore and the appropriate data were collected using the newly designed equipment when the subjects were participating in the 100m race. The collected data were treated with appropriate statistical techniques and obtained Reliability, Validity and objectivity of the device. Normally in 100mts sprint, starting point to 40mts prevailing as acceleration phase, 40mts to 80mts as flying sprint phase and 80mts to 100mts prevailing as deceleration phase, which is resulting from the international athletes 100mts sprinting events performances.
