Context: The presence or absence of biomechanical differences between the sexes before puberty may provide clues about the onset of adult landing pattern differences, which may help to explain the greater number of anterior cruciate ligament injuries in females than in males and provide the basis for interventions to reduce those injuries. Objective: To identify developmental sex-related and biomechanical differences during vertical jump landings. Design: A 2 3 2 developmental stage (prepubescent or postpubescent) 3 sex (male or female) between-subjects design. Setting: Controlled laboratory setting. Patients or Other Participants: Thirty prepubescent subjects (15 boys, age 5 9.63 6 0.95 years; …
