| description | Objectives: The purpose of this study was to investigate
the effect of transverse plane foot position on lower limb
kinematics during a single leg squat.
Methods: This was a cross-sectional study conducted
among highly-trained male athletes. Only participants
who showed normal knee valgus during a drop landing
screening test were recruited. Twelve junior athletes performed
single leg squats while maintaining a knee flexion
angle of 60�. The squats were executed in three foot positions:
neutral (0�), adduction (�10�), and abduction
(þ10�). Three-dimensional motion analysis was used to
capture the lower extremity kinematics of the participants’
preferred limb. The hip and knee kinematics in the
sagittal, frontal, and transverse planes during squatting
were compared across the three foot positions using oneway
ANOVA.
Results: The participants showed a normal range of dynamic
knee valgus (5.3��1.6). No statistically significant
differences were observed in hip flexion (p ¼ 0.322),
adduction (p ¼ 0.834), or internal rotation (p ¼ 0.967)
across different foot positions. Similarly, no statistically
significant differences were observed in knee flexion
(p ¼ 0.489), adduction (p ¼ 0.822), or internal rotation
(p ¼ 0.971) across different foot positions.
Conclusion: Small changes in transverse plane foot position
do not affect lower extremity kinematics during
single leg squat in highly trained adolescent males with
normal dynamic knee valgus. Our findings may provide
guidance on safer techniques for landing, pivoting, and
cutting during training and game situations. |
