This study looks at whether the physical fitness of young judo athletes before a match can help predict how their bodies and effort perception respond after a match. Judo matches are short, intense and tiring. After a match, athletes show higher blood lactate (a marker of intense effort), weaker grip strength and lower jump height. Not much is known about whether baseline tests of core endurance, throwing power, speed, agility and force-velocity profile can predict these changes in young athletes. Male judo athletes aged 10-13 years will complete these baseline tests in one session and then take part in one 3-minute simulated judo match with a training partner of similar body mass. Blood lactate, vertical jump height and grip strength will be measured before and right after the match, and athletes will rate how hard the match felt. The study will examine how the changes after the match relate to the baseline test results. The findings may help coaches monitor training load and plan conditioning for young judo athletes.
Judo is a high-intensity intermittent combat sport. Matches produce marked blood lactate accumulation, loss of handgrip strength, and reduced lower-body power. Baseline physical profiling is widely used to monitor athletic development, but its ability to predict individual physiological and perceptual responses to a judo match in young athletes is not well understood.
This is a single-group, pre-post study. Fifteen male judo athletes aged 10-13 years will be recruited in Malatya, Turkey. Written informed consent will be obtained from parents or legal guardians, and assent from participants. About one week before testing, participants are familiarized with the procedures and the Borg 6-20 rating of perceived exertion (RPE) scale. Participants avoid high-intensity training, caffeine and ergogenic supplements for 48 hours before testing. Testing takes place in a climate-controlled hall (20-22 °C).
Test day: After anthropometric measurements, baseline profiling is performed: McGill core endurance tests (trunk flexion, trunk extension, right and left lateral bridge), a 2-kg backward overhead medicine ball throw, a 20-m sprint, the pro-agility test, and a force-velocity profile using Samozino's field method (MyJump2 app, 240 fps video). After a standardized 10-minute warm-up (low-intensity jogging, dynamic stretching, breakfalls), pre-match measures are taken: blood lactate (finger-prick capillary sample, single-use lancet), countermovement jump height (contact mat) and handgrip strength (hand dynamometer).
Athletes then complete one 3-minute simulated judo match (randori) under International Judo Federation rules with a training partner of similar body mass (±5 kg), supervised by a coach. Immediately afterwards, blood lactate, jump height, grip strength and RPE are measured in this order within about 3 minutes.
Pre- and post-match values are compared with paired-samples t-tests (Cohen's d). Change scores (post minus pre) for lactate, jump height and grip strength, and RPE, are related to baseline variables using Pearson correlation and simple linear regression. The sample size (minimum 15) was calculated with G*Power for a paired t-test (d = 0.80, alpha = 0.05, power = 0.80).

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Male judo athletes aged 10-13 years complete baseline physical profiling, followed by one standardized 3-minute simulated judo match. Blood lactate, jump height, grip strength and perceived exertion are measured before and immediately after the match.
Other: Simulated Judo Match · Diagnostic Test: Baseline Physical Performance Profiling
One 3-minute simulated judo match (randori) performed under International Judo Federation rules against a training partner of similar body mass (±5 kg), supervised by a coach. Athletes are instructed to fight at maximal competitive intensity.
Also known as: Randori
McGill core endurance tests, 2-kg backward overhead medicine ball throw, 20-m sprint, pro-agility test and force-velocity profile (Samozino's field method). Followed by pre- and post-match measures of blood lactate, countermovement jump height, handgrip strength and rating of perceived exertion.
Change in Blood Lactate Concentration After a Simulated Judo Match
Change (post-match minus pre-match) in capillary blood lactate concentration (mmol/L), measured from a finger-prick sample with a portable lactate analyzer. The relationship of this change with baseline physical performance variables is also analyzed.
Time frame: Immediately before and within 3 minutes after the simulated match (single test session)
Change in Countermovement Jump Height After a Simulated Judo Match
Change (post-match minus pre-match) in maximal isometric handgrip strength (kg) of the dominant hand, measured with a hand dynamometer (best of two trials).
Time frame: Immediately before and within 3 minutes after the simulated match (single test session)
Rating of Perceived Exertion (RPE) After a Simulated Judo Match
Perceived effort of the simulated match rated on the Borg 6-20 RPE scale (6 = no exertion, 20 = maximal exertion).
Time frame: Within 30 seconds after the simulated match (single test session)
Change in Handgrip Strength After a Simulated Judo Match
Change (post-match minus pre-match) in maximal isometric handgrip strength (kg) of the dominant hand, measured with a hand dynamometer (best of two trials).
Time frame: Immediately before and within 3 minutes after the simulated match (single test session)
Plan to share: No — Individual participant data will not be shared, because participants are minors and the consent forms state that data will be used only for the purposes of this research and kept confidential. Aggregate results will be published.
Start is estimated for Jan 2027; primary completion for Feb 2027, 1 month later.
Of 936 non-industry interventional studies with no phase under Fatigue, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 27. This study's planned 1 month is below that.
Counting every sponsor, half of 989 studies reached it within 11 months; a quarter within 5 and three quarters within 27.
