Priming Using Contrast Training Exercise
Sponsor: The Jerzy Kukuczka Academy of Physical Education in Katowice
Summary
This study investigated the effects of a morning complex-contrast training session on afternoon sport-specific and physical performance in competitive judokas. The study focused on identifying whether a stimulus targeting both force and velocity components of the force-velocity curve could induce a "delayed potentiation" effect 6 hours later and whether these responses differed by sex.

Interventions
Morning Complex-Contrast Training
At approximately 9:00 AM, participants completed a standardized warm-up consisting of a 10-minute self-paced jog followed by dynamic stretching. Baseline countermovement jump and maximum isometric handgrip strength measurements were subsequently performed. The CCT intervention consisted of: 3 lower-body contrast sets, with 6 repetitions of the back squat paired with 6 maximal countermovement jumps; 3 upper-body contrast sets, with 6 repetitions of the bench press paired with 6 maximal wall ball slams. After completing the morning session, participants underwent a 6-hour passive recovery period. At approximately 3:00 PM, they repeated the standardized warm-up and completed the countermovement jump, maximum isometric handgrip strength, and Special Judo Fitness Test assessments.
Time-Matched Walking Control Condition
At approximately 9:00 AM, participants completed a standardized warm-up consisting of a 10-minute self-paced jog followed by dynamic stretching. Baseline countermovement jump and maximum isometric handgrip strength measurements were then performed. Following the baseline measurements, participants walked for the duration required to complete the CCT protocol in the experimental condition. After the 6-hour recovery interval, participants returned at approximately 3:00 PM, repeated the standardized warm-up, and completed the countermovement jump, maximum isometric handgrip strength, and Special Judo Fitness Test assessments.
