Scoring: Record the total distance covered for each trial, and the total distance overall. After 35 seconds, the participants repeat this 30-s shuttle five more times (total 6 x 30 seconds). During the recovery period, the players make their way back to the starting point. There is a 35 second recovery period between trials. A whistle is blown after 30 seconds, and the total distance during that time (to the nearest 2.5m) is recorded. At each marker, the hand is used to touch the ground at the level of the marker (in the original test description by Pendleton 1997, the foot only touched each marker). They continue this pattern to the 15m, 20m and 25m marker. They then turn and run to the marker at 10m and return. When instructed by the timer, the subject runs to the first marker (at 5m), turns and returns to the starting line. Participants start with a foot at the end line. Procedure: This is a maximal test, the subject should be instructed to run as hard as they can in each trial, and avoid pacing. You may also want to place down smaller markers every 2.5m to increase the accuracy of recording the distance reached during each shuttle. See more details of pre-test procedures.Ĭourse layout: marker cones and/or lines are placed every 5 meters along a 25m distance. Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Perform screening of health risks and obtain informed consent. Pre-test: Explain the test procedures to the subject. The authors recommend that CRF, assessed by the 20mSRT, be considered as an international population health surveillance measure to provide additional insight into pediatric population health.Ĭardiorespiratory fitness children criterion-referenced standards normative data reliability validity.Purpose: this is a test of anaerobic power and agility.Įquipment required: stopwatch, measuring tape, marker cones, whistle, a flat non-slip surface. The assessment is pragmatic, easily interpreted, and results are transferable to meaningful and understandable situations. The authors show that the 20mSRT is an acceptable, feasible, and scalable measure of CRF and functional/exercise capacity, and that it has moderate criterion validity and high to very high reliability. This review aims to clarify the international utility of the 20mSRT by synthesizing the evidence describing measurement variability, validity, reliability, feasibility, and the interpretation of results, as well as to provide future directions for international surveillance. The 20-m shuttle run test (20mSRT)-a progressive aerobic exercise test involving continuous running between 2 lines 20 m apart in time to audio signals-is probably the most widely used field test of CRF. ![]() Field testing offers a simple, cheap, practical alternative to gas analysis. Although gas-analyzed peak oxygen uptake is the criterion physiological measure of children's CRF, it is not practical for population-based testing. In children, CRF is meaningfully associated with health, independent of physical activity levels, and it is an important determinant of sports and athletic performance. Cardiorespiratory fitness (CRF) is a good summative measure of the body's ability to perform continuous, rhythmic, dynamic, large-muscle group physical activity, and exercise.
