# 30m Sprint Fatigue Power Maintenance 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

The objective of this test is to monitor the athlete's power maintenance - sprint fatigue.

### Required Resources

To undertake this test you will require:

• 400m track
• 12 Cones
• Stopwatch
• Assistant

### How to conduct the test

This test requires the athlete to complete 10 x 30m sprints.

• The athlete warms up for 10 minutes
• The assistant sets up the course as per the diagram opposite using the cones
• The assistant gives the command "GO" and starts the stopwatch
• The athlete sprints from A to B between the cones deviating 5m sideways in the middle of the sprint
• The assistant stops the stopwatch when the athlete's torso crosses the finish line at B and records the time
• The athlete jogs slowly back to point A (taking no longer than 30 seconds to do so) following the route on the diagram
• The athlete is to complete a total of 10 sprints from A to B and the assistant is to record the times

### Assessment

Enter the athlete's times for the ten sprints and then select the 'Calculate' button.

#### Sprint Fatigue

Using the 10 recorded sprint times subtract your fastest time from your slowest time. For example if your slowest sprint was 7.8 seconds and your fastest sprint was 6.9 seconds your sprint fatigue is 0.9 (7.8 - 6.9).

#### Power Maintenance

Determine the average speed of the first three trials and divide it by the average speed of the last three trials. So if your times were...

• 7.1 seconds, 6.9 seconds, 6.9 seconds
• 7.0 seconds, 7.2 seconds, 7.1 seconds, 7.3 seconds
• 7.3 seconds, 7.4 seconds, 7.5 seconds

The average of the first 3 times (7.1, 6.9, and 6.9) is 6.97 seconds and the average of the last 3 times (7.3, 7.4, and 7.5) is 7.40 seconds.

Power Maintenance = 6.97 ÷ 7.40 = 0.94 (Excellent)

• Excellent 0.9
• Good 0.85 to 0.899
• Average 0.80 to 0.849
• Poor <0.799

### Analysis

Analysis 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 power maintenance (sprint fatigue).

### Target Group

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

### 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. The following link provides a variety of factors that may influence the results and therefore the test reliability.

### 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.

• Minimal equipment required
• Simple to set up and conduct
