Introduction: The pre-season should be planned by technicians and physical trainers to achieve maximum physical performance and to decrease the negative effects of the training process in the handball players. Objective: This study evaluated the effect of the loads selective periodization on physical performance and hematological parameters during the pre-season in handball players. Methods: Sixteen Under-16 male handball players from the Caçador team (Brazil) participated in the study. The periodization of pre-season was composed of 3 mesocycles of training. Variables of physical performance, erythrogram and leukogram in the beginning of the pre-season and in the final pre-season were evaluated. Results: Using selective loads periodization, the body composition improved in the final pre-season compared to the beginning of the pre-season (p<0.01). Periodization increased maximum isometric strength by 6.4%, muscle endurance during sit-up and push-up tests by 9.6% and 26.2%, respectively, muscle power of the lower and upper limbs by 6.6% and 5.7%, respectively, and flexibility by 7.6% in the final pre-season when compared to the beginning of the pre-season (p<0.05). Furthermore, the periodization improved the agility of the athletes reducing the time by 3.1% when compared with the beginning of pre-season (p<0.05). White blood cells and red blood cells did not modify during all pre-season (p>0.05). Conclusion: Selective loads periodization is effective to improve physical performance during pre-season in Under-16 male handball players.
