Edgren Side-Step Test (ESST)
The Edgren 10-second side step test (ESST) is a test of side-stepping ability, quickness and agility. The ESST was first introduced in the literature in 1932 by Harry D. Edgren to assess lateral mobility in basketball players. See also the modified Edgren sidestep test.
equipment: flat, non-slip floor, with line markings or cones (can use masking tape), tape measure, stopwatch.
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.
test setup: Five cones or lines are placed in a line, three feet apart (12 feet total between the two outside cones).
procedure: The starting position is at the centre cone, facing forward with feet straddling the center line. At the command 'go', the participant sidesteps to the right until their right foot touches or crosses the outside cone or tape mark. The participant then sidesteps to the left until their left foot touches or crosses the left outside cone or tape mark. The participant sidesteps back and forth to the outside cones as rapidly as possible for 10 seconds.
scoring: Count the number of cones/lines crossed. Deduct a point if the far end lines are not reached, if they fail to keep their trunk and feet pointed forward at all times, or crosses the legs. The best results of three trails should be recorded.
variations: a metric version is sometimes used, resulting in a slightly longer course of 4 m in length with four 1 m (3.28 ft) increments. The modified Edgren Side Step test is just one timed shuttle.
