For characterization of the participants, body composition (body mass, body fat, height), O2MAX and the peak height velocity were evaluated according to previous studies (Léger & Lambert, 1982; Mirwald, Jones, Bailey, & Beunen, 2002; Machado, Oikawa & Barbanti, 2013).

Determination of Anaerobic Power
To measure the aerobic power (fatigue index, minimum power, peak power and average power) of the players, the Running-based Anaerobic Sprint Test - RAST (Zacharogiannis, Paradisis, & Tziortzis, 2004) was used.

The last stage was computed for the O2MAX determination (Krustrup et al., 2006). The Kuipers, Verstappen, Keizer, Geurten, and Kranenburg (1985) equation was used to calculate the maximum intensity (VMAX) reached during the protocol as shown below:
VMAX = Ecom + (t/DE) * I

The training session to develop aerobic power during the preparatory stage in the 1st and 2nd weeks was consisted of five series of three minutes at 90% of VMAX with 90 seconds of active recovery. The 3rd, 4th and 5th weeks were consisted by three sets of five minutes at 95% of VMAX with 90 seconds of active rest.
