EXPLORING GENDER DIFFERENCES AND
BIOMECHANICS OF ACL INJURIES DURING
SINGLE-LEG LANDINGS AND INTERNAL
ROTATION LANDINGS USING INERTIAL
MEASUREMENT UNITS AND FORCE PLATES
ABSTRACT
RESEARCH BACKGROUND
Anterior Cruciate Ligament (ACL) injuries not only require lengthy recovery periods but
also pose a risk of long-term joint degeneration. Dynamic knee valgus and high vertical

ACL injuries. Understanding biomechanical differences between landing techniques

Recreation Management study aims to explore these differences to enhance training protocols and reduce the

METHODOLOGY
A repeated measurement study was used for the experiment, with a total of 30
OBJECTIVES participants (15 males and 15 females) aged between 18-30. The subjects wore Inertial
Measurement Units (IMUs) to capture knee valgus joint angle and landing of a force

biomechanical adaptations may have converged across males and females, likely due
to comparable training intensities and landing techniques.
ABOUT THE INVESTIGATOR
I am passionate about basketball and dedicate my free time to studying strength and
conditioning. My ambition is to become a professional sports therapist, where I plan
to go beyond traditional methods and develop specific protocols and training plans to
enhance athletic performance and reduce injury risks. My previous experiences in this
field have further fueled my motivation to pursue a career as a sports therapist. Mr. HO
