Leg Strength 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.

Objective

To monitor the development of the athlete's elastic leg strength.

Required Resources

To undertake this test you will require:

  • 400 metre track - 25 metre marked section on the straight
  • Cones
  • Stop Watch
  • Assistant

How to conduct the test

Mark out a 25 metre section on the straight section of the track with two cones. The athlete starts 10 to 15 metres behind the starting line. Using a jog run up, the athlete starts hopping on the dominant leg from the first cone. The time taken to hop between the two cones is recorded. The test is then repeated with the other leg.

Analysis

Analysis of the result 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.

Target Group

This test is suitable for active individuals but not for those where the test would be contraindicated.

101 Performance Evaluation Tests

Reliability

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.

Validity

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.
