- W2013115009 abstract "1036 The purpose of this study was to assess linear and parallel activation of the 3 superficial heads of the quadriceps femoris muscles during sub-maximal isometric contractions. 30 healthy, volunteers were assessed for isometric EMG activity of the vastus medialis (VM), vastus lateralis (VL), and rectus femoris (RF) muscles with the knee at 60 deg of flexion. Subjects performed 5 s isometric contractions equivalent to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% of the average of three maximal voluntary contractions (MVC), in a random order. Full-wave rectified and integrated EMG signals over the middle 3 s of each contraction were expressed as a percentage of the activity recorded during the averaged MVC's. One sample t-tests and 95% confidence intervals were calculated at each relative torque level. A 2 factor ANOVA (muscle by intensity) with repeated measures was performed to evaluate parallel activation across the intensity levels. Activation linearity was assessed via regression analysis for each muscle. VM activation was shown to be significantly lower than the expected %MVC at 20% to 70%. VL and RF activation were significantly higher than expected at 10% MVC, and RF EMG was less than expected at 40% to 70% MVC. VM EMG was shown to increase significantly more than the VL and RF from 80% MVC to 90% MVC. Significant linear and quadratic relations were also demonstrated for all 3 muscles. Parallel activation of the superficial quadriceps muscles was observed from low to moderate intensities, while convergence was noted at near maximal intensities." @default.
