Knee extensor maximum voluntary torque (MVT)– and QEMG_MVT–angle relationships during maximum isometric contractions performed at knee-joint angles of 35°, 50°, 65°, 80°, and 95°. Both relationships, MVT–angle (a) and QEMG_MVT–angle (b), showed a main effect of angle (one-way ANOVA P < 0.001) with post-hoc differences denoted by: *higher than the other angles, ^§lower than the other angles, ^†lower than 50° and 80°, ^≠higher than 35°, 50°, and 65°, and ^‡higher than 65°. Data are mean ± SD (n = 28). M_MAXP–P supramaximal M-wave peak-to-peak amplitude, QEMG_MVT quadriceps femoris EMG at maximum voluntary torque
