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).

Conditions

No Condition, Basic Science

Keywords

PAPE; Judo; Warm-Up

Outcome Measures

Primary Outcomes (1)

• Special judo fitness test (SJFT)

  Three sets of time-limited judo throws, assessing the number of throws

  15 seconds for the 1st set, 30 seconds for sets #2 and #3

Secondary Outcomes (2)

• Heart rate

  During the SJFT, immediately after the SJFT, and 1 minute after the SJFT

• Rate of perceived exertion

  30 minutes after each testing session

Study Arms (4)

Upper body PAPE protocol

EXPERIMENTAL

Half of the judo-specific protocol + 3 sets of 10-second hold isometric push-ups.

Other: Warm-up (specifically, Post-Activation Performance Enhancement)

Lower body PAPE protocol

EXPERIMENTAL

Half of the judo-specific protocol + 3 sets of 6 repetitions of standing broad jump.

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.

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).

Other: Warm-up (specifically, Post-Activation Performance Enhancement)

Interventions

Warm-up (specifically, Post-Activation Performance Enhancement) OTHER

Assess which intervention delivered the best acute performance enhancements.

Combined (Upper body+Lower body) PAPE protocol; Control (judo-specific) protocol; Lower body PAPE protocol; Upper body PAPE protocol

Model Details: 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.
