Association Between Isokinetic Knee Strength Characteristics and Single-Leg Hop Performance In Healthy Young Participants
Objective
The purpose of this study was to determine the extent to which the mean peak moment (MPM) of knee flexors and extensors could predict performance in a group of healthy individuals.
Methods
Eighty-four healthy individuals—32 men and 52 women (mean age, 22.1 ± 3 years; range, 18-35 years)—participated in this study. Isokinetic unilateral concentric knee flexor and extensor MPM was assessed isokinetically at angular velocities of 60°/s and 180°/s. Functional performance was assessed using the single hop of distance (SHD).
Results
Positive moderate to good statistically significant correlations (r = .636 to r = .673) were found between knee flexor and extensor MPM at 60°/s and 180°/s for the SHD test. Knee flexor and extensor MPMs are strong predictors for the SHD test at 60°/s and 180°/s (R2 = .40 to R2 = .45).
Conclusion
Knee flexor and extensor strength was substantially correlated with SHD.
