Comparison of Isokinetic Muscular Strength of the Knee Joint according to the Ankle Joint Position
Objectives: The purpose of the study was to investigate the effect of the position of the ankle joint on the isokinetic muscular strength of the knee joint. Methods/Statistical Analysis: The subjects of this study were 20 young and healthy adult females who were applied at random ankle joint positions and underwent the flexion and extension of the knee joint. Isokinetic muscle strength was measured for each process at an angle speed of 60°/sec with CSMI. The comparison of knee muscle strength for each ankle position was conducted by a one-way ANOVA. Post hoc tests utilized LSD. Findings: When the knee joint was extension at a 40° plantar flexion, it showed a significant difference regarding the neutral position and the position of the 20° dorsiflexion (p<.05). Knee flexion did not show a significant difference depending on the position of the ankle joint (p>.05). The muscle strength rate of the knee joint showed a significant difference for the neutral position and the position of the 20° dorsiflexion at the position of a 40° plantar flexion (p<.05). Improvements/Applications: We propose that the position of plantar flexion was the most effective at expressing maximum muscle strength when doing an isokinetic knee extension exercise.
