Intervention model: CROSSOVER
Intervention model description: A randomized crossover research design was used to analyze the effects of three PAPE-aimed conditioning exercises on the SJFT performance. The participants attended a total of five sessions during the study. The first session was used to familiarize the participants with the PAPE-aimed conditioning exercises. The participants had previous experience with the SJFT; however, the protocol was re-explained and performed by the participants during the familiarization session. The use of the RPE scale was also explained during this session, and demographic data were collected. Participants performed the three experimental protocols (i.e., combined, upper-body, lower-body) and the control condition (i.e., judo-specific warm-up) in four separate sessions (≥48 hours of recovery between sessions) in random order. All the testing sessions were conducted between 1400 and 1600 hours with an environmental temperature of approximately 28° C.
Primary purpose: OTHER

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.

Eligibility criteria: Inclusion Criteria:

* Minimum of 4 years of judo training and competition experience.
* Actively practicing the sport and preparing for a competition during the time of data collection
* Proficient at performing the ippon seoi-nage throwing (judo) technique

Exclusion Criteria:

* Disease or serious injury that inhibited participating in the warm-up protocols and subsequent testing sessions.

Primary outcomes:

Secondary outcomes:
