| Resource requirements | 1 | Equipment = audio device, speakers, cones to mark length [36]. Space = flat surface, indoor (preferred) or outdoor (weather dependent), 20 m in length + room to turn round, 1-m width per child [36]. Human = 2 members of staff = one to ensure protocols are followed correctly, one to record scores [36]. Training = CD provides audio instructions = no technical training required [36] | 1 | Equipment = stopwatch. Space = outside measurable area, flat surface, no standard surface for this test therefore outdoor 400-m athletics track [10], dirt track [17], or grass athletics track [39] suitable. Human = two members of staff = one to time and one to record results [10, 17]. Training = no advanced technical training requirements | |

| Practical implementation issues | 2 | For a single study, 22 (37.9 %) children and 25 (33.3 %) adolescents experienced some degree of DOMS, from which six children (10.3 %) and four adolescents (5.3 %) indicated that their DOMS was severe. Three (2.3 %) subjects reported having severe pain in the upper body, 29 (21.8 %) in lower body, and 14 (10.5 %) in the whole body. Most (39 participants; 29.3 %) assumed that the 20-m shuttle run test could be the cause. For 11 (19 %) children and 14 (18.7 %) adolescents, DOMS caused difficulties in daily activities, especially stair climbing and walking [34] | 1 | Participants may have difficulty in developing an appropriate pace; participants may either start too fast so that they are not able to keep up the speed all through the test, or they may start too slow so that when they want to increase speed, the test is already finished [4] | |
