 ABSTRACT

AGOSTINHO, M. F. Effects of the traditional periodization model on physical performance, competitive performance and technical variation of young judo athletes. Dissertação (Mestrado em Ciências) – Escola de Educação Física e Esporte, Universidade de São Paulo, São Paulo. 2015.

The aim of this study was investigate the influence of the traditional periodization model (with multiple peaks) on physical fitness in field tests, competitive performance and technical variation in judo competitions. In this sense, the sample consisted of Junior and Cadet athletes who were monitored over two annual training seasons (12 athletes per season) in which internal training load parameters (Training Load  and Training Strain) of each training period were quantified through the session rating of perceived exertion. Physical performance was evaluated when the periods of training were changed, measuring lower limbs muscle power (standing long jump), upper limbs dynamic strength endurance (dynamic judogi chin up) and aerobic and anaerobic fitness in a specific situation (SJFT - Special Judo Fitness Test). Additionally, in main competitions, fights were filmed for later quantification of competitive performance (winning percentage, points scored, points conceded, attack efficiency index and effectiveness index) and technical variation (throwing techniques, groundwork techniques and directions of throws). The variables were compared by mixed model for repeated measures analysis, followed by Bonferroni test. The associations among variables were tested by Pearson’s or Spearman’s correlation coefficient. In the 2011 season, there were differences (P <0.05) in the Training Load, Training Strain, standing long jump, dynamic judogi chin up, winning percentage, points scored, points conceded, attack efficiency index, directions of throws and throwing techniques, in addition to correlation between the Training Load three days before a regional championship and the attack efficiency index in this competition (r = - 0.832; P = 0.001; very large). In 2012 season, there were differences (P <0.05) in Training Load, Training Strain, standing long jump, dynamic judogi chin up, SJFT variables (number of  throws, heart rate one minute after the test and index), points scored and throwing techniques, in addition to correlations between the number of throws in SJFT with the attack efficiency index (r = 0.629; P = 0.028; large) and winning percentage (r = 0.634; P = 0.027; large) in a inter-regional championship. The relevance of monitoring the internal training load and the physical performance was reinforced by the associations with competitive performance parameters. Although physical performance, competitive performance and technical variation have changed over the seasons, these variations occurred in an unsynchronized way, apparently without influence of the training loads adopted. Thus, the results of this study indicate that for young judo athletes, the traditional periodization model (with multiple peaks) does not develop continuous adaptations of the performance parameters analyzed, but it seems to be effective in increasing the physical performance early in the season and subsequent stabilization of the adaptations.
