400m Drop Off 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 this test is to monitor the athlete's anaerobic efficiency.

Required Resources

To conduct this test, you will require:

  • 400m track.
  • Stopwatch.
  • Cones.
  • Assistant.

How to conduct the test

This test requires the athlete to sprint 100 metres, and after a short recovery, sprint 400 metres.

  • The athlete warms up for 10 minutes.
  • The assistant marks out a 100-metre straight section on the track.
  • The assistant gives the command “GO” and starts the stopwatch.
  • The athlete runs at full speed over 100 metres.
  • The assistant stops the stopwatch when the athlete's torso crosses the finishing line and records the time.
  • The athlete takes a five-minute recovery.
  • The assistant gives the command “GO” and starts the stopwatch.
  • The athlete runs at full speed over 400 metres.
  • The assistant stops the stopwatch when the athlete's torso crosses the finishing line and records the time.
  • The assistant converts the 400-metre time to 100-metre splits by dividing the time by four and then subtracts the 100-metre time to give the drop-off time.

Assessment

I have been unable to locate any normative data for this test.

Enter times for the 100m and 400m and then select the 'Calculate' button.

100m time secs   400m time secs     Drop-off of secs

Example

  • 100m time = 13.0 seconds.
    400m time = 60.0 seconds.
    60 ÷ 4 = 15 seconds.
    15 - 13 = a drop-off time of 2 seconds.

The aim is to reduce the 'drop off' time by increasing anaerobic efficiency. A top female 400m athlete will have a drop-off time of around 0.7 seconds.

Analysis

Analysis of the test result is done 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 efficiency.

Target Group

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

Reliability

Test reliability refers to how a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strictly 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.

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 is required.
  • Simple to set up and conduct.

Disadvantages

  • Specific facilities required - 400m track.
  • An assistant is required to administer the test.
