Not Applicable

Completed

• Conditions: No Condition, Basic Science

• Registration Number: NCT06768723
• Lead Sponsor: Universidade do Porto

Brief Summary

The study aimed to investigate the post-activation performance enhancement (PAPE) of the special judo fitness test (SJFT) of youth judo athletes using upper-body (isometric push-ups), lower-body (standing broad jumps), or their combination as conditioning exercise (CE).

Detailed Description

Fourteen females (aged 16.5 ± 0.8 yrs) and nine males (aged 17.0 ± 0.9 yrs) performed the three CEs or a control condition (i.e., judo-specific warm-up) in a randomized crossover method. The SJFT was conducted one minute after the CE or control condition.
