This study aimed to analyze the effects of a specific physical training season, conducted concomitantly to the State championship, on muscle strength, speed and power in U-19 basketball players (n = 14; 18 ± 1 years old; 86.2 ± 10.2 kg of body weight; 1.92 ± 0.1 m o f height). A double periodization model was used in the physical develop ment program that was divided into the following periods: general preparatory, specific preparatory and co mpetitive. The periodization was planned without any

... interference of the researchers. At five mo ments of the season ( weeks 1, 8, 25, 39 and 49) the fo llo wing parameters were assessed: maximal strength (1RM), sprints over 30 m (nu mber of[NS]; mean speed over 30 meters (V 30 ). maximal speed[Vmax]; t ime to attain maximal speed[AT]) and ju mps (Squat Ju mp[SJ], counter-movement ju mp without arms[CMJ] and counter-movement ju mp with[CMJA]). The results showed that at the finals of the championship significant increases (p<0,05) in V 30 and AT were observed. The other parameters (1RM, SJ, CMJ, CMJA,Vmax and NS) d id not change throughout the season (p>0,05). Thus, it can be concluded that only the time to attain it (acceleration) and V 30 were sensitive to the training periodization proposed by the technical co mmission during the 49-week co mpetitive season.
