Comparability of modified and standardized test conditions for the 6-minute run

Purpose In order to avoid cost-intensive laboratory-based test procedures, test systems based on field tests are used for health and fitness assessments in schools. For measuring cardiovascular endurance, various methods are used in practice to indirectly estimate VO2max. One method frequently used is to set a time frame for participants to achieve the highest total running performance possible. Methods The 6-minute run (6MR) was carried out in different geometric dimensions. The test was carried out at three time points in time on three different running tracks (T1-6MR-9×18: rectangle = 9 meters × 18 meters, T2-6MR-9×6: rectangle = 9 meters × 6 meters, T3-6MR-400 = ellipse = 400 meters) and the differences in the results were assessed. Results Significant differences in total distance running were found between the rectangular running tracks (T1-6MR-9×18 = 1295 meters (± 96) and T2-6MR-9×6 = 1297 meters (± 101) in the sports hall and the elliptical running track outdoor (T3-6MR-400 = 1362 meters (± 126). No differences were found between the two rectangular running tracks (T1-6MR-9×18 and T2-6MR-9×6). Conclusion These results indicate that existing reference values for the 6-minute run can also be used for assessment if the running test is carried out up to a minimum size of 9 meters × 6 meters.
