Development of Test Speed Hand and Leg Reaction Tests in Branch Sports Branches Tarung Derajat

This study aims to simplify the implementation of the reaction speed test where the tools developed are simplified because remembering the measurement tool of the reaction speed test that was previously very minimal procurement for the tool is also a high price in the financing of the tool, so that with this research can help trainers in carrying out physical conditions tests specifically in the reaction speed test instrument in the Tarung Derajat sport. The research method is a development research method. This research was conducted through 3 stages of research, namely pre-development, development and application in different groups. The study population was Tarung Derajat athletes from POPNAS, POMNAS, Pra-PON North Sumatra. The sampling technique uses purposive sampling and there are 20 people. The control group was 20 Pra-PON athletes. The instrument used was the data analysis technique of the Hand & Foot Speed Reaction tool using the T test. The results of the study concluded: with the development of a tool simplified to the hand and foot reaction speed test it is expected that there will be the same results as the developed instrument so that the tool can later used by trainers and KONI district cities in terms of physical condition tests specifically on the test of the reaction speed of the hands and feet of Tarung Derajat Athletes.
