# 1200m Shuttle Test (1.2SRT)

The 1200m Shuttle Test is an aerobic fitness test involving running to-and-from a start line to 20, 40 and 60-m marks, 5 times without a break (Kelly & Wood, 2013). This test is commonly used to test rugby players, and to them it is known as the Bronco test. The score from this test can be used to calculate maximal aerobic speed.

purpose: the purpose of this test is to a get an estimate of maximal aerobic running speed.

equipment required: stopwatch, measuring tape, marker cones, a flat track or grass surface.

pre-test: Explain the test procedures to the subject. Perform screening of health risks and obtain informed consent. Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Measure and mark out the test area. Perform an appropriate warm-up. See more details of pre-test procedures.

procedure: The participants start at a baseline and run 20 meters forwards then returned to the baseline, they then ran 40 meters forwards and returned to the baseline again and finally run 60 meters forwards and return to the baseline. They repeat this sequence five times as fast as possible, covering a total of 1200 meters. Ensure the foot touches or goes over each line. The participants should be instructed to run maximally throughout the test to achieve the best result.

scoring: Record the total time in seconds to complete the test, which usually lasts 5-6 minutes. Elite rugby players can score between 4-5 minutes in this test. All black Beauden Barrett has one of the best scores of 4min 12seconds.

The maximal aerobic speed can be calculated by dividing the 1.2km distance by the time to complete the test, with a small correction as in the following equations. The webpage I got these equations listed their source as Kelly, Jackson & Wood (2014), however that article does not include any equations like this, so I don't know where they came from. It may be from Baker & Heaney (2015).

Equation for athletes with a heavy body mass (approx. 100 kg):

MAS (m/s) = 1200 / (time in seconds – 29)

Equation for athletes with a light body mass:

MAS (m/s) = 1200 / (time in seconds – 20.3)

target population: suitable for athletes involved in many multi-sprint sports such as basketball, hockey, rugby, soccer.

comments: This is a maximal effort anaerobic test, and in order to receive the highest score the participants must sprint at 100 percent effort the entire test. You should encourage the athletes not to pace themselves, the best score is achieved by going at 100% effort from the start.
