Background: Reaction time is the ability to respond quickly to a stimulus. Athletes can improve reaction times by training to make the right choices (choice reaction).Simple reaction time is very important in activities such as 100 meter sprint on the track or in the pool. There are various methods to measure reaction time but most of these methods require expensive machines or computer software. Other common method to measure reaction time is the meter stick test or the Ruler Drop Test. Objective: To prove intrarater reliability of measuring reaction time with audio visual reaction time machine and ruler drop test. Methods: Design: Analytical study. Subject: Total 92 female subjects were taken for the study. Informed consent was obtained. Reaction time measured with audio visual machine and Ruler Drop Test. Reaction time was noted. After a gap of one day both the test were done again. Reaction time was measured. Same procedure was repeated twice and data was noted. Result: Interclass correlation method (ICC) was used to prove intrarater reliability of the tests to measure reaction time. Intrarater reliabilities for audio visual reaction time machine (ICC=0.889) were higher than for ruler drop test (ICC=.743). Conclusion: These results show that both these tests are highly reliable for measuring reaction time and ruler drop test can also be used in cases where audio visual reaction time machine is not present.

Key words: Reaction time, Ruler Drop Test, Audio visual reaction time machine
