The purpose of this study was to assess the neuromuscular activation patterns of four synergistic muscles of the quadriceps femoris (QF), including the vastus intermedius (VI) muscle, during concentric and eccentric isokinetic knee extensions at 30, 90 and 120 deg/sec. Ten healthy men (age, 21.0 ± 0.6 year; height, 170.3 ± 4.8 cm; weight, 62.6 ± 6.4 kg) performed maximal voluntary isokinetic knee extension at knee joint angle from 80° to 160° (full extension = 180°). Surface electromyography (EMG) was recorded from the four individual muscles of the QF. The normalized EMG amplitude of the VI was significantly higher at knee joint angle between 80° and 100° during both the concentric and eccentric phases in all angular velocities compared to that of the rectus femoris (P < 0.05). The present results suggest that VI could highly contribute at the flexed position during concentric and eccentric phases of isokinetic knee extension as has been found in previous studies.
