The Effects of a 12-week Block Periodization vs. Daily Undulating Periodization on Muscular Strength and Cognitive Function in Healthy Young Adults.

Sponsor: Gdansk University of Physical Education and Sport

View on ClinicalTrials.gov

Summary

This study compared the effects of two resistance training periodization models, block periodization and daily undulating periodization, on muscular strength and force production in healthy young adults with limited resistance training experience. Participants were randomly assigned to a block periodization group, a daily undulating periodization group, or a non-training control group. The two training groups completed three supervised resistance training sessions per week for 12 weeks. Both training programs used the same exercises and were designed to have similar total training volume and average programmed relative intensity, but differed in how training volume and intensity were organized over time. Muscular strength and force production were assessed before and after the intervention using the isometric mid-thigh pull and single-joint isometric strength testing of the knee and elbow.

Interventions

BEHAVIORAL

Block Periodization Resistance Training

Participants completed a 12-week supervised block periodization resistance training program with three sessions per week. Training was organized into four consecutive three-week blocks. The programmed relative intensities across the four blocks were approximately 70%, 83%, 78%, and 90% of estimated 1RM, respectively, with corresponding changes in sets and repetitions. Exercise selection, total programmed training volume, and average programmed relative intensity across the 12-week intervention were matched to the Daily Undulating Periodization group. Loads were individually adjusted based on performance and repetitions in reserve (RIR).

BEHAVIORAL

Daily Undulating Periodization Resistance Training

Participants completed a 12-week supervised daily undulating periodization resistance training program with three sessions per week. Training volume and relative intensity varied between sessions within each weekly microcycle, using loading conditions corresponding to approximately 70%, 78%, 83%, and 90% of estimated 1RM across the intervention. Exercise selection, total programmed training volume, and average programmed relative intensity across the 12-week intervention were matched to the Block Periodization group. Loads were individually adjusted based on performance and repetitions in reserve (RIR).
