Figure 2. Maximal torque of dominant leg m. quadriceps obtained during maximal voluntary isometric contraction (MVC, a) and electrically evoked torque of m. quadriceps femoris using stimuli trains at 100 Hz (P100, c) and 20 Hz (P20, b) and expressed as 20/100 Hz torque (d) ratio immediately before (Pre) and 10 min after (Post) each of nine training sessions as well as 3, 10 and 17 days after cessation of training (group mean ± SD). * P < 0.05 compared to value before the first training session.
