The purpose of the present study was to investigate the electromyography (EMG)-knee joint angle relationship and the differences in activity among the four quadriceps femoris (QF) muscles during maximal voluntary isometric knee extensions. Ten well-trained healthy male volunteers (mean ± 1 standard deviation (SD) age 33 ± 11 years, height 1.83 ± 0.07 m, body mass 79 ± 4.7 kg) performed maximal isometric knee extensions in a seated position at four different knee joint angles (90º, 65º, 40º, and 15º of knee flexion). Myoelectric activity was simultaneously recorded from rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM), and vastus intermedius (VI) using fine-wire EMG. Root-mean-square (RMS) was calculated during a sustained ph...
