About this study
Official title: Effects of Post-activation Performance Enhancement Protocols Using Upper-body, Lower-body, or Combined Upper- and Lower-body Exercises on Judo-specific Performance: a Randomized Crossover Trial
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).
Read the 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.

| Study group | Role | What they receive |
|---|---|---|
| Upper body PAPE protocol | Experimental | Half of the judo-specific protocol + 3 sets of 10-second hold isometric push-ups. Receives: Other: Warm-up (specifically, Post-Activation Performance Enhancement) |

| Combined (Upper body+Lower body) PAPE protocol | Experimental | Half of the judo-specific protocol + 3 sets of 3 repetitions of standing broad jump + 3 sets of 5-second hold isometric push-ups. Receives: Other: Warm-up (specifically, Post-Activation Performance Enhancement) |
| Control (judo-specific) protocol | Active comparator | Judo-specific exercises that included 10 repetitions of ukemi drills (i.e., front, back, side, and rolling), 2 sets of 10 repetitions of "rapid" uchikomi drills (i.e., throwing drills), 2 sets of 1 minute of kumikata fight (i.e., grip fight), and 2 sets of 10 repetitions of nagekomi (i.e., practice throws). Receives: Other: Warm-up (specifically, Post-Activation Performance Enhancement) |

- 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.
