• Resumen

  • The purpose of this study was to evaluate the maximal oxygen uptake (V O2max) values in soccer players as assessed by field and laboratory tests. Thirty-five elite young soccer players were studied (mean age 18.1 ± 1.0 years, training duration 8.3 ± 1.5 years) in the middle of the playing season. All subjects performed 2 maximal field tests: the Yo-Yo endurance test (T1) for the estimation of V O2max according to normogram values, and the Yo-Yo intermittent endurance test (T2) using portable telemetric ergospirometry; as well as 2 maximal exercise tests on the treadmill with continuous (T3) and intermittent (T4) protocols. The estimated V O2max values of the T1 test (56.33 ml·kg-1·min-1) were 10.5%, 11.4%, and 13.3% (p <= 0.05) lower than those of the T2 (62.96 ml·kg-1·min-1), T3 (63.59 ml·kg-1·min-1) and T4 (64.98 ml·kg-1·min-1) tests, respectively.

    Significant differences were also found between the intermittent exercise protocols T1 and T3 (p <= 0.001) and the continuous exercise protocols T2 and T4 (p <= 0.001). There was a high degree of cross correlation between the V O2max values of the 3 ergospirometric tests (T2 versus T3, r = 0.47, p <= 0.005; T2 versus T4, r = 0.59, p <= 0.001; T3 versus T4 r = 0.79, p <= 0.001).

    It is necessary to use ergospirometry to accurately estimate aerobic capacity in soccer players. Nevertheless, the Yo-Yo field tests should be used by coaches because they are easy and helpful tools in the training program setting and for player followup during the playing season.
