300-yard Shuttle TestTesting and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we need to consider the factors influencing the results. ObjectiveThe objective of the 300-yard Shuttle Test (Jones 1991)[1] is to monitor the athlete's intermediate anaerobic power (lactate system).
Required ResourcesTo conduct this test, you will require:
How to conduct the testThis test requires the athlete to complete ten shuttle runs between two cones 30 yards apart as fast as possible.
AssessmentThe following table, adapted from Hoffman(1961)[2], is for professional baseball players.
AnalysisAnalysis of the test result is by comparing it with the athlete's previous results for this test. It is expected that, with appropriate training between each test, the analysis would indicate an improvement in the athlete's anaerobic energy system. Target GroupThis test is suitable for active individuals but not for those where the test would be contraindicated. It is a practical test for game players (e.g. football, rugby, hockey, basketball, squash, tennis, badminton) as the shuttle format makes it sport-specific. ReliabilityTest reliability refers to how 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 influencing the results and test reliability. ValidityTest validity refers to the degree to which the test measures what it claims to measure and the extent to which inferences, conclusions, and decisions based on test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development. Advantages
