Key result
Pre-participation dominant hamstring/quadriceps ratio at 60º/s significantly predicted lower limb injuries in elite judokas (AUC 0.702; 95% CI 0.520-0.883; p=0.023).
Why the study?
The association between pre-participation knee muscle strength status and the occurrence of lower limb injuries needed investigation.
Does pre-participation knee muscle strength status predict lower limb injury occurrence in elite judokas?

Isokinetic knee muscle dynamometry is useful for predicting the likelihood of lower limb injuries in professional judokas during competitive activity.
May support pre-participation isokinetic testing for injury prediction in judokas; leaves open causal effects and intervention efficacy.
The association of pre-participation knee muscle strength status with lower limb injury occurrence was investigated. Knee extensors and flexors muscle strength status including the traditional hamstrings/quadriceps (H/Q), Q/Q, H/H, and the non-dominant H/Q: dominant H/Q, HQ:HQ, ratios were recorded before the 10 month judo activity. Fifteen lower limb sport injuries were recorded for 53 judokas during the follow-up questionnaires. Significant accuracy of dominant H/Q ratio 60º/s (AUC 0.702, 95% CI 0.520 to .883, p = 0.023), as well as HQ:HQ ratios 300º/s (AUC .318, 95% CI 0.138 to 0.497, p = 0.040), and 60 º/s (AUC 0.311, 95% CI 0.130 to 0.491, p = .033) were revealed discriminating between injured and uninjured judokas. The optimum cut-off of dominant H/Q ratio associated with belonging to uninjured judokas group was 43.2% (sensitivity, 0.974; specificity, 0.533). Isokinetic knee muscle dynamometry is useful for predicting the likelihood of lower limb injuries in professional judokas during competitive activity.

Darbandi et al. (2022) conducted a cohort in Lower extremity injuries (n=53). Pre-participation knee muscle strength status was evaluated on Lower limb injury occurrence (AUC 0.702, 95% CI 0.520 to 0.883, p=0.023). Pre-participation dominant hamstring/quadriceps ratio at 60º/s significantly predicted lower limb injuries in elite judokas (AUC 0.702; 95% CI 0.520-0.883; p=0.023).
