Ruler Drop Test
Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but in the analysis we need to bear in mind the factors that may influence the results.
The objective of this test is to monitor the athlete's reaction time.
To undertake this test you will require:
How to conduct the test
The algorithm to calculate the reaction speed is d = vt + ½at² where
We need to manipulate d = vt + ½at² to give us an algorithm for t
As v = 0 then vt = 0 therefore the algorithm is t = Sqrt(2d/a)
Normative data for the Ruler Drop Test
The following are national norms, adapted from Davis (2000) for 16 to 19 year olds.
Analysis of the results is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement in the athlete's reaction speed.
This test is suitable for all athletes but not for individuals where the test would be contraindicated.
Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test. The following link provides a variety of factors that may influence the results and therefore the test reliability.
Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development.
