The Interval Shuttle Run Test (ISRT) is a fitness test designed to assess the ability to recover and repeat intermittent activity. Developed by Lemmink et al. in 2000, this test is commonly used for team sport players and athletes involved in intermittent sports.
Purpose
The purpose of the Interval Shuttle Run Test is to evaluate an individual’s capacity to engage in intermittent activity and effectively recover between intervals.

Equipment required
To conduct the test, you will need a clear flat area that is at least 20m long, an audio recording of the test, and marker cones.
Test Layout

The test layout requires marking out a 20m area with markers at either end. Additionally, place markers 3 meters before each end line to create tolerance zones.
Test Procedure
The test involves running for 30 seconds alternated with 15 seconds of walking. Participants start running on the first “beep” and aim to reach the opposite end by the next “beep.” This cycle continues until a double beep indicates the end of the 30-second period. Participants then walk forward to the next line and wait for the start of the next level in 15 seconds.
The running speed starts at 10 km/hr and increases by 1 km/hr every 90 seconds. Once the running speed reaches 13 km/hr, the increase in speed is reduced to 0.5 km/hr. The test concludes when the athlete fails to make it into the tolerance zone twice.

The test score is determined by the number of fully completed 20-meter runs.
Advantages
The Interval Shuttle Run Test is particularly relevant for sports that involve intermittent activity, making it more suitable than the commonly used beep test.
Disadvantages
One of the main drawbacks of this test is the lack of normative values due to its less common usage. Additionally, creating or obtaining the necessary audio recording can be challenging.
