| description | injuries. However, studies on the top down kinetic chain of lower limb mechanics during dynamic motions
such as single leg squat (SLS) among trained males were scarce.
Objective: The objective of the study was to evaluate the relationship between isokinetic hip and knee strength
and frontal plane projection angle (FPPA) of the knee joint during SLS.
Methods: Thirty-two male junior athletes (twelve cyclists, ten runners and ten squash players) were screened
for excessive dynamic knee valgus (DKV) prior to participation. Only those within the normal value of DKV were
included. Their hip and knee isokinetic strength in sagittal plane were evaluated at 60º/s of angular velocity
for both legs using dynamometer. Two dimensional knee FPPA was evaluated during SLS at 60º of knee flexion.
Pearson correlation was evaluated between knee FPPA during SLS and isokinetic leg strength.
Results: Correlations between knee FPPA and hip and knee isokinetic strength were not statistically significant
except between knee flexion peak torque/body weight (r = -0.35, p = 0.05) and hamstring to quadriceps ratio
(r = -0.39, p = 0.03) of non-dominant leg.
Conclusions: Isokinetic hip and knee strength and knee FPPA during SLS was correlated only for non-dominant
leg during SLS among male junior athletes. DKV during SLS may be reduced through strengthening the muscles
around hip and knee joints. |
