The purpose of this experiment was to determine
biomechanical risk factors for knee injury between horizontal
and vertical landing conditions. This experiment was
performed using a 3 dimensional motion camera system,
reflective markers, and two force plates. There were twelve
participants who were all physically active females age 18-25.
They each performed three vertical and three horizontal
landing trials. The variables analyzed included ground
reaction force which was used to calculate loading rate, knee
orientation angle, and sagittal and frontal joint knee
moment. It was found that loading rate was higher in the
horizontal component; there was greater knee flexion angle
in the vertical direction. Varus knee moment was greater in
the horizontal direction, and greater knee extension moment
in the horizontal direction. In conclusion, the horizontal
landing conditions result in greater risk of knee injury.
