fibers, therefore, may be recruited at lower forces than the smaller fibers, which may explain atypical changes in the frequency parameters of the surface electromyography with increasing force of contraction. 11 The authors found significant differences in median frequency parameters between lower back

Electromyographic amplitude of the VL and VM muscles was captured in accordance with the Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles. 17 The electromyographic assessment was conducted at the same time as the dynamometric
