Fig 2. Time course changes in joint torque, joint angle, and timing of electrical stimulation in three contraction conditions.

Fig 2

The vertical dotted line shows the onset of electrical stimulation. The filled circles show the timing of joint toque measurement (DF5°, PF0°, and PF5°, respectively). CON; concentric contraction without preliminary contraction, ECC; concentric contraction after preliminary eccentric contraction, ISO; concentric contraction after preliminary isometric contraction, DF; dorsiflexion, PF; plantarflexion.
