Abstract
We examined the effects of a four week ACL injury risk reduction training intervention program on ground reaction force, knee flexion and knee valgus during landing in female high school soccer players. Twenty three female soccer players (Age = 16 + or - 1 yrs) completed 8 sessions with a member of the research team consisting of a 20-30 min warm-up protocol designed to improve balance, coordination, agility, lower body strength and flexibility. Emphasis during training was placed on landing lightly on the balls of their feet, in a flexed knee position and with knees shoulder width apart. The athletes had been playing soccer for 10 + or - 2 yrs, had a BMI of 22 + or - 3 kg/cm super(2) and all except 2 had normal menstrual cycles. There were no injuries sustained during practice or games during the study period.
