The present study had as objective to investigate the alteration dynamics of the vertical jump explosive power (VJ), the horizontal jump explosive power (HJ) and the fast horizontal power to the right leg (STCD) and left leg (STCE) in the distinct preparation stages in adult basketball players submitted to the block training system. The group studied was composed of 12 athletes from the main league who participate in the São Paulo State Basketball Championship (A1). Eight athletes fully accomplished the program and were included in the analysis. The athletes were submitted to a preparation bicyclical structure (first macro-cycle with 23 weeks and the second with 19 weeks). In the structuring of the model, the macro-cycle was divided in basic stage (power concentrated loads), special stage and competition stage. The basic stage had duration of eight weeks in the first training macro-cycle and three weeks in the second macro-cycle. The athletes were evaluated in eight distinct moments of the annual cycle, characterizing a longitudinal investigation. The results demonstrated: 1) the efficiency of the block training system in basketball, evidenced by the punctual expression of the posterior long-lasting training effect (PLTE); 2) the competition loads presented different effects for VJ and HJ and 3) several occurrences verified between STCD and STCE, demonstrating the necessity of evaluating and analyzing in details the results of the different jump tests when used as control parameters of the training effects.
