Klatt Test

Testing 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.

Objective

The objective of the Klatt tests (1988) is to assess an athlete's balance, stability and jumping as a prerequisite to undertaking a plyometrics program.

Required Resources

To conduct this test, you will require:

Gym
Assistant

How to conduct the test

Balance and Stability

These tests are performed on bare feet (shoes and socks off).

Stand erect on one foot

Lift the free leg so the thigh is parallel with the ground and the lower leg hangs straight with the toes pulled up (dorsiflexed)

Hold this position for 10 seconds and observe any deviation or shaking

Repeat with the other leg

Perform a single leg squat with bends at the hip, knee and ankle

Hold at the lowest point for 10 seconds

Observe the squat depth and any deviation or shaking to compare with the other leg

Repeat the single leg squat with the other leg

Results for each leg should be similar

Jump Tests

These tests should be performed wearing trainers.

Bunny hop for 20 metres and hold the final hop in the down position for 10 seconds

Observe the squat depth and any deviation or shaking to compare with the other leg

Record the number of hops (X)

Perform a single leg hop for (X) hops

Observe hip stability on the landing of each hop

Record the distance

Hold the last hop in the down position for 10 seconds

Observe the squat depth and any deviation or shaking to compare with the other leg

Repeat with the other leg

Analysis

Distances achieved with the bunny hop and the two single-leg hops should be similar, squat depth similar and held for 10 seconds with minimal deviation and shaking.

On the single-leg hops, the hips must remain stable on landing - if not then single leg plyometric work should be avoided until hip stability can be maintained.

Target Group

This test is suitable for pubescent male and female athletes.

Reliability

Test reliability refers to how a test is consistent and stable in measuring its intended 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 various factors influencing the results and test reliability.

Validity

Test 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

Minimal equipment required
Simple to set up and conduct

Disadvantages

Specific facilities required
Assistant required to administer the test
