Interrater and Intra-rater Reliability of the Ball Speed Radar Gun Application to Measure Balling Speed in Cricket Ballers

Abstract

Background: Balling in cricket is an action of propelling the ball towards the wickets defended by a batter

and has always been given a special attention. The tools that measure balling speed are not easily accessible

and are expensive and the accessible ones are not reliable. The aim of our study is to establish the Interrater

and Intrarater reliability of one such application available on google play, the ball speed Radar gun.

Method: In our study we approached various cricket clubs and cricket set up in and around Pune out of

which 30 players were selected based on inclusion and exclusion criteria. The balling speed was recorded

by the Ball speed radar gun Application and Data was Collected whose Baseline data values in terms of

Age in years (22.66±2.70), BMI in kg/m2(23.12±2.98), Hours of practice in hours(4.12±1.31) and Years of

Experience (2.93±0.91) are comparable at P=0.05 and analysed for Interrater and Intrarater reliability.

Result: In our study we established good Intrarater (k=0.988) and Interrater (k= 0.980) reliability at P=0.05

for the application.

Conculsion: From our study we conclude that Ball speed radar gun application is reliable to measure

bowling speed.
