Introduction: Our study aims to examine the metabolic response to the effort of the water polo players, in correlation with the effort zones and the training intensity, by measuring the blood lactic acid. The specialty literature is poor in data about the metabolic cost of the effort in children and juniors - water polo, as compared to seniors. Methods: We used 3 swimming drills specific to the following effort zones: Anaerobic threshold (20 x 50 m Freestyle / start at every 50 sec.), VO2 max (3 x (4 x 100 m Freestyle) / a 10 sec. break between repetitions and a 5 min. break between series) and Tolerance to lactate (6 x 200 m Freestyle / start at every 7 min.), as well as 2 drills specific to the game phases: the former is addressed to the anaerobic threshold effort zone (20 x 25 m ball carrying / a 10 sec. break), while the latter simulates a game action: attack 10 m Freestyle - fallback 10 m Backstroke - counter-attack 10 m Freestyle - shot on goal preceded by two feints. The results of the collected blood tests were analyzed and interpreted at the Biochemistry Lab within the INCS - Bucharest, by means of the ABL 835 Analyzer and of the SPOTCHEM EZ Dry Chemistry Analyzer, Model: SP - 4430 - Arkray. Results: The values of the blood lactic acid concentration during the 3 swimming drills were: Anaerobic threshold - basal mean 2.27 mmol / after the effort 8.68 mmol, VO2 max - basal mean 0.92 mmol / after the effort 10.86 mmol, Tolerance to lactate - basal mean 1.61 mmol / after the effort 12.50 mmol. Game-specific drill 1 - anaerobic threshold - basal mean 0.6 mmol / after the effort 9.76 mmol; game-specific drill 2 - basal mean 2.7 mmol / after the effort 9.07 mmol. Discussions: By analyzing the obtained results, we can assert that the junior water polo players are not ready to swim with specific tempo and rhythm means, that is why they don`t keep to the intensities imposed by the effort zones and their metabolic cost is higher than the effort requirements. The effort at the anaerobic threshold intensity has a lactic acid accumulation in the blood of 8.68 mmol, on an average, for the swimming drills, and of 9.76 mmol, for the polo game-specific drill 1, which corresponds to the VO2 max zone.
