Reaction time (RT) is one of the fitness components based on motor skills and vital to health-related skill. It’s important to sprinting events which requires fast starting to win a race. The SMART Whole-Body Reaction Time 515-GM instrument is a new tool to measure whole-body reaction time. Normally reaction time tested individually but this instrument able to measure five subjects one-shot. This cross-sectional study is involved as much as 80 respondents, which consists of 40 males and 40 females and collected randomly. The SMART Whole-Body Reaction Time 515-GM is correlated with Nelson Choice Reaction Time to examine its validity. The retest procedure is applied to find the reliability of the new instrument. By applying the Pearson product Moment correlation test, this study found that the result of validity and reliability are more than 0.80. It indicates that a new SMART Whole-Body Reaction Time 515-GM instrument fulfils the requirement of a testing protocol. Also, it has high validity and reliability and acceptable. In conclusion, the instrument can reduce cost, time and can use to test many subjects efficiently and effectively. © 2020, Institute of Advanced Scientific Research, Inc.. All rights reserved.
