Introduction:. Because of the game duration and intensities, soccer is mainly dependent upon aerobic metabolism. The studies have shown that football players at a lower level of aerobic capacity (VO2max) have much lower average distance, with a more walking and jogging, while players on the higher level of VO2max cover more distance by running and sprinting (Verheijen, 1997). In most cases, laboratory tests for assess VO2max are not available in practice, so we’re forced to evaluate aerobic capacity with field tests. Two very common field tests in football are multistage fitness test (MST) and Hoff test (HOFF). Correct training program can improve VO2max, and guided with this thought, we have asked ourselves if there are any changes in the VO2 max at young football players in competitive season. Methods: Twenty young football players (Age=13.0±0.2 yrs ; H=156.3±1.9 cm ; W=47.7±2.3 kg) were taken from the football school in Croatia. All subjects performed MST and HOFF, as specific football. Tests are conducted approximately every 3 months, at the beginning and end of the spring and autumn season. Based on the results of the tests we estimate VO2max for each player. The ANOVA and the Bonferoni test were used to determine differences in observed variables between the four time points. Results: By analyzing the data we obtained statistically significant differences in VO2max in both tests. The result (in finish level) of MST in four time points was (9.0±0.2 at 1st ; 9.7±0.2 at 2nd ; 9.9±0.9 at 3th and 10.8±0.2 at 4th) and estimate VO2max (43.2±0.9 at 1st ; 45.9±0.7 at 2nd ; 46.9±0.8 at 3th and 49.6±0.7 mlO2/kg/min at 4th). The result of HOFF (in m) was (1458.1±24.1 at 1st, 1569.9±26.6 at 2nd, 1524.5±26.0 at 3th and 1576.5±24.4 at 4th) and estimate VO2max (ml/kg/min) was (55.8±1.2 at 1st ; 61.2±1.2 at 2nd ; 59.7±1.1 at 3th and 61.7±1.2 at 4th). The trend of body height and weight was regular for all 4 measurements (H1=156.3cm ; H2=160.8cm ; H3=162.8cm ; H4= 167.5cm ; W1=47.8kg ; W2=18.7kg ; W3=162.8kg ; W4=167.5kg). Conclusion: Based on the test results we can conclude that change in VO2max in young footballers is statistically significant. Although we can see the difference in VO2max between MST and HOOF, which is probably a consequence of specific movement structures of HOFF, we can see a trend of growth in one and another for approximately 10.5%. In this study raises the question how great the impact of the growth and development on VO2max is and how great is the impact of training on VO2max.
