    BACKGROUND: Neuropsychological capabilities in athletes may be associated with a predisposition to anterior cruciate ligament (ACL) injuries. OBJECTIVE: Assess differences between male and female athletes in jump-landing technique in relation to their neuropsychological capabilities. DESIGN: Experimental. SETTING: Laboratory. PARTICIPANTS: 31 recreational athletes, free from lower extremity injuries, participated (females: n=16, age=21.01.71 years, mass=65.15.6 kg, height=174.268.9 cm; males n=15, age=22.32.2 years, mass=77.98.9 kg, height=185.778.7 cm). ASSESSMENT OF RISK FACTORS: Reaction time (RT) under stress was measured. Furthermore, participants conducted anticipated (ANT) and unanticipated (UNANT) double-legged drop-jumps, followed by running at 4.5-5.5 m/sec 45$^rc$ to the left, straight, or 45$^rc$ to the right, depending on the light indication prior to landing on the force plates. MAIN OUTCOME MEASURES: RT and joint kinematics (trunk flexion-TF, ankle flexion-AF) and kinetics (knee abduction moment-KAM, ankle extension moment-AEM) at peak vertical ground reaction force (vGRF,N/kg). Moments are expressed as external moments (Nm/kg). Pearson product-moment correlation between RT and joint biomechanics. RESULTS: During UNANT, KAM became significantly larger (P=.010) in females (-0.370.1) than males (-0.160.1). TF was greater in the AT (29.7$^rc$3.3$^rc$) than UNANT (46.1$^rc$3.1$^rc$) regardless of gender (P
