Effect of Block Periodization on Performance in Competition in a Soccer Team during Four Consecutive Seasons: A Case Study

Mallo, J.

The aim of this study was to assess the impact of implementing block periodization on the performance of a Spanish professional soccer team across four consecutive seasons. A longitudinal training plan was developed, dividing each season into three stages, further segmented into three training blocks or mesocycles: Accumulation, Transmutation, and Realization. Each block focused on developing a minimal number of physical capacities. Training workloads were analyzed by comparing the time dedicated to developing each physical capacity within blocks. Team performance in competition was evaluated by examining the percentage of points obtained in each match relative to the training block. Results indicated that time allocated to developing high-intensity aerobic and gym-based strength was highest during the Accumulation phase (P<0.001 and P<0.05, respectively), speed endurance during Transmutation (P<0.05), and speed during Realization (P<0.05). The team achieved the highest success percentage in competition during Realization blocks (χ2 (2)=6.23; P<0.05), garnering 59% of the points in play. These findings suggest that block periodization could serve as a viable training strategy for professional soccer teams, with enhanced competitive performance observed during Realization blocks.
