Core Endurance and Throw Performance in Young Judokas (JUDO-CORE)
Associations of Core Endurance With Medicine Ball Throw Performance and Static Balance in Young Male Judokas: A Cross-Sectional Study
Visão geral do estudo
Status
Descrição detalhada
Judo is a high-intensity combat sport that requires explosive power, postural control, balance, and efficient force transmission throughout the kinetic chain. Core musculature plays a central role in stabilizing the trunk and transferring force between the lower and upper extremities during sport-specific movements. In judo, throwing techniques such as ippon-seoi-nage, uchi-mata, and harai-goshi require substantial trunk stabilization and rotational force production.
Although previous studies have investigated the importance of core training and trunk muscle function in athletic performance, limited evidence exists regarding the association between core endurance and sport-related performance parameters in young judokas. Understanding these relationships may provide valuable insights for training program design in youth judo athletes.
Therefore, the purpose of this cross-sectional observational study is to examine the association between core endurance, medicine ball throw performance, and static balance in male judokas aged 10-13 years.
Twenty male judokas with at least two years of regular judo training experience will participate in the study. Core endurance will be evaluated using McGill's isometric core endurance test battery, including trunk flexion, trunk extension, right lateral bridge, and left lateral bridge tests. Explosive upper-body performance will be assessed using the backward overhead medicine ball throw test with a 2-kg medicine ball. Static balance performance will be evaluated using the Flamingo Balance Test.
Data collection will be conducted over two testing sessions separated by at least 48 hours. Spearman rank correlation analyses and regression analyses will be used to examine the relationships between variables.
The study hypothesizes that greater core endurance will be positively associated with medicine ball throw performance and static balance performance in young male judokas.

Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: judokas
A single group of 20 young male judokas (aged 10-13 years) who underwent physical performance testing, including core endurance, medicine ball throw, and static balance assessments.
|
Participants performed four isometric endurance tests: trunk flexor, trunk extensor, and right/left lateral bridge tests to assess core stability.
Used to measure explosive power.
Participants threw a 2 kg medicine ball backward over their head for maximum distance
A static balance test where participants stood on one leg on a metal beam for as long as possible
