Interesting Research Article: Effects of Pubertal Maturation on ACL Forces During a Landing Task in Females
Effects of Pubertal Maturation on ACL Forces During a Landing Task in Females Nasseri et al: American Journal of Sports Medicine Sept 2021 Rates of anterior cruciate ligament (ACL) rupture in young people have increased by >70% over the past two decades. Adolescent and young adult females aged 15-19 years are at higher risk of ACL injury as compared with their prepubertal counterparts. On the basis of the Tanner classification system, 19 pre-, 19 early-/mid-, and 24 late-/postpubertal females performed a standardized drop-land-lateral jump while 3-dimensional body motion, ground-reaction forces, and surface electromyography data were acquired. The data were used in a validated computational model to estimate ACL loading. Results: When compared with pre- and early-/midpubertal females, late-/postpubertal females had significantly higher ACL force. No differences were found between pre- and early-/midpubertal groups in ACL force or its contributors. Gr...
