RAST Test
Objective Test
Draper and Whyte (1997) developed the Running-based Anaerobic Sprint Test (RAST) to test a runner's anaerobic performance. RAST is similar to the Wingate ANaerobic 30 cycle Test (WANT) in that it provides coaches with measurements of power and fatigue index. WANT is more specific for cyclists whereas the RAST provides a test that can be used with athletes where running is the primary method of movement.

Required Resources
To undertake this test, you will require:

400-metre track
Two Cones
Two Stopwatches
Two Assistants
How to conduct the test
This test requires the athlete to undertake six 35 metre sprints with 10 seconds recovery between each sprint.

The 1st assistant weighs and records the athlete's weight
The athlete warms up for 10 minutes
The assistants mark out a 35 metre straight on the track with the cones
The assistants each have a stopwatch
The athlete completes six 35 metre runs at maximum pace with 10 seconds allowed between each sprint for a turnaround as follows:
The athlete, using a standing start, gets ready to sprint
The 2nd assistant gives the command GO for the athlete to start and the 1st assistant starts his/her stopwatch
When the athlete completes the 35 metres the
1st assistant stops his/her stopwatch, records the time and resets the stopwatch
2nd assistant starts his/her stopwatch to time the 10-second turnaround
When 10 seconds have elapsed the 2nd assistant gives the command GO for the athlete to start, rests the stopwatch and the 1st assistant starts his/her stopwatch
3 and 4 are repeated six times
Assessment
Power output for each sprint is found using the following equations

Velocity = Distance ÷ Time
Acceleration = Velocity ÷ Time
Force = Weight × Acceleration
Power = Force × Velocity
OR

Power = Weight × Distance ² ÷ Time ³
From the six times calculate the power for each run and then determine:

Maximum power = the highest value
Minimum power = the lowest value
Average power = sum of all six values ÷ 6
Fatigue Index = (Maximum power - Minimum power) ÷ Total time for the 6 sprints
Maximum Power
Is a measure of the highest power output and provides information about the strength and maximal sprint speed. Research range is 1054 watts to 676 watts.

Minimum Power
Is the lowest power output achieved and is used to calculate the Fatigue Index. Research range is 674 watts to 319 watts.

Average Power
The higher the score the better the athlete's ability to maintain anaerobic performance over time.

Fatigue Index
Indicates the rate at which power declines for the athlete. The lower the value the higher the ability of the athlete to maintain anaerobic performance. With a high fatigue index value (more than 10) the athlete may need to focus on improving their lactate tolerance.

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 anaerobic capacity.

Target Group
This test is suitable for sprint and endurance athletes and players of endurance sports (e.g. football, rugby) 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. Research by Marcos et al. (2013) concluded that the RAST test was not a valid method to evaluate cyclists' anaerobic power performance considering the Wingate test as a reference.

Advantages
Minimal equipment required
Simple to set up and conduct
Can be conducted almost anywhere
Disadvantages
Specific facilities required
Assistant required to administer the test
