Key result
Female and male elite judokas showed no differences in Single Leg Squat test performance or hip external rotation, but differed in hip internal rotation, which may affect ACL injury risk.
Why the study?
ACL injury is the most serious injury in judo and typically more prevalent in women, prompting investigation into whether movement patterns differ between sexes among elite judokas to identify those at higher risk.
Are there sex-based differences in movement patterns related to ACL injury risk among elite judokas?
Cross-Sectional
Are there sex-based differences in movement patterns related to ACL injury risk among elite judokas?
Elite judokas show sex-based differences in hip internal rotation, which may relate to ACL injury risk, but not in other movement patterns like the Single Leg Squat test.
Answers are grounded in this paper and cite their sources.
Sex differences limited to hip internal rotation in elite judokas are hypothesis-generating for ACL risk; cross-sectional data leave causal and clinical implications open.
The anterior cruciate ligament (ACL) injury is the most serious injury in judo. Therefore, its prevention is of great importance. The main mechanism of injury is the collapse of the knee in valgus, which usually occurs when there are deficits of strength and neuromuscular control of the core, external rotators and hip abductors, as well as limitations of ankle and hip mobility. In most sports there is a difference in the prevalence of this injury between both sexes, being more common in women. Therefore, in the present study we observed this possible intersexual disparity in the difference of movement patterns among elite judokas according to their sex, in order to identify those athletes with a higher risk of ACL injury. In addition, it was not observed differences between sexes in the performance of the Single Leg Squat test (SLS test); There was worse neuromuscular control of the non-dominant leg in men and women; No differences were observed in in the range of motion of ankle dorsiflexion and hip external rotation between men and women, but there were differences in internal rotation, a movement whose restriction may be related to an increased risk of ACL injury.

Prados-Barbero et al. (2023) conducted a cross-sectional in Anterior Cruciate Ligament (ACL) injury risk. Female sex vs. Male sex was evaluated on Differences in movement patterns (Single Leg Squat test, neuromuscular control, range of motion). Female and male elite judokas showed no differences in Single Leg Squat test performance or hip external rotation, but differed in hip internal rotation, which may affect ACL injury risk.
