Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players’ physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players. Therefore the present study aimed to, on the basis of previous studies evaluate the advantages and disadvantages of the five most commonly used field test; to analyze the physiological requirements on soccer players with respect to their aerobic and anaerobic capacity; and last to compare among the five field tests and evaluate the validity of the field tests through comparison of field tests results with results from laboratory and soccer matches. During soccer match about 75-96 % of the energy is provided by the aerobic systems, while the rest, 4-25 %, is provided by the anaerobic systems. This fits approximately most of the results from both field tests and laboratory tests through measurement of either pulse, running distance, VO2max or lactate. Among the five tests, Yo-Yo tests (YIRT and YIET) has the best correlation to soccer match with respect to physiological demands on both aerobic and anaerobic capacities. Among the different Yo-Yo tests YIRT2 seems to be the best compared to YIET1, YIET2 and YIRT1.
