SJFT Performance, Inhibitory Control, and Attention in Young Judokas
The Relationship Between Special Judo Fitness Test (SJFT) Performance and Inhibitory Control and Selective Attention in Young Judokas
This study will examine the relationship between judo-specific physical fitness and cognitive performance in young male judo athletes and will evaluate the immediate effects of the Special Judo Fitness Test (SJFT) on attention and inhibitory control. Licensed male judo athletes who train regularly at least three days per week will be compared with male participants who do not actively participate in sports.
Judo athletes will complete a standardized warm-up followed by the SJFT, a judo-specific high-intensity fitness test involving repeated throws performed over three short exercise periods separated by brief rest intervals. Heart rate will be measured immediately after the SJFT and again one minute later.
Cognitive performance will be assessed using a computerized Flanker Task, which will measure reaction time and response accuracy while participants respond to relevant visual information and ignore distracting information. Judo athletes will complete the Flanker Task approximately one minute before and one minute after the SJFT. Participants in the control group will complete the same cognitive assessment twice over a similar time interval without performing the physical exercise.
The study will aim to determine whether judo-specific physical fitness and judo experience are associated with attention and inhibitory control and whether a single high-intensity judo-specific exercise session will produce an immediate change in cognitive performance.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: Judo Group
Participants in the judo group will complete a standardized warm-up followed by the Special Judo Fitness Test (SJFT).
Cognitive performance will be assessed using the Flanker Task approximately one minute before and one minute after the SJFT.
|
The Special Judo Fitness Test is a judo-specific high-intensity exercise test consisting of three exercise periods: 15 seconds, 30 seconds, and 30 seconds, with 10-second rest intervals between periods.
During the test, the participant will perform as many ippon-seoi-nage throws as possible using two partners positioned six meters apart.
|
|
No Intervention: Control Group
Participants in the control group will not perform the SJFT or any other exercise intervention.
They will complete the Flanker Task twice over a similar time interval while remaining at rest.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Flanker Task Correct Responses
Time Frame: Approximately 1 minute before and 1 minute after the intervention
|
Response accuracy will be assessed using a computerized Flanker Task.
The number of correct responses will be recorded separately for congruent and incongruent trials.
Higher numbers of correct responses indicate greater response accuracy.
|
Approximately 1 minute before and 1 minute after the intervention
|
|
Change in Flanker Task Reaction Time
Time Frame: Approximately 1 minute before and 1 minute after the intervention
|
Reaction time will be assessed for congruent and incongruent trials using a computerized Flanker Task.
Lower reaction times indicate faster cognitive responses.
|
Approximately 1 minute before and 1 minute after the intervention
