conditions by being assessed through Inertial Measurement Units (IMU) and force
TAI WING YI plates?
2. Is there an interaction effect between subject groups within task conditions in ACL

To perform a SLDL, begin by raising the dominant leg off the ground. Then, bend the
knee and hip to effectively absorb the impact. Throughout the movement, engage the
core muscles to enhance balance and stability.
OBJECTIVES During the dual-task scenario, participants will be instructed to assume the appropriate
position and anticipate catching a regulation-size basketball at chest level. The
The study will specifically concentrate basketball will be thrown by the researcher without any predetermined bias towards

ABOUT THE INVESTIGATOR
Hello, I'm Zoey. I am dedicated to becoming a professional sports therapist. Under the
guidance of my FYP supervisor, Mr. Indy HO, I am actively developing my skills and
knowledge in this field. I am fascinated by the intersection of sports, rehabilitation,
and performance. My goal is to help athletes recover from injuries, optimize their
performance, and support their overall well-being. I am excited to make a positive
impact on the lives of athletes and contribute to the field of sports therapy.
