Prior to the application of the stimulating and electromyography (EMG) electrodes, the underlying skin was prepared by shaving, lightly abrading, and cleansing (using isopropyl alcohol.) Peak twitch force of the triceps surae muscle group was evoked using bipolar surface electrodes placed on the popliteal fossa overlying the medial popliteal nerve (cathode) and ~2 cm below the distal border of gastrocnemius (Hamada et al., 2000b).

legs on the ground, at an arm's length from the wall, body is slightly bent forward, keeping it straight in the front; from this position is made the return to vertical position by contracting the triceps surae muscle 2 x 10 repetitions with the injured limb, and then with the uninjured one;

However, tight controls over many exercise parameters such as comfortable body support, isolation of the triceps surae muscle group, controlled range of motion, and measurement of work and power are lacking.
(Figure 1) Together with the gastrocnemius, and soleus, they are collectively referred to as the triceps surae muscle. The muscle originates from the lateral supracondylar line of the femur just superior and medial to the lateral head of the gastrocnemius muscle as well as from the oblique popliteal ligament in the posterior aspect of the knee.
The muscle force of the GM was estimated by multiplying the measured torque by the relative contribution of the physiological cross-sectional area of the GM (18%) within the plantar flexor muscles (Kubo et al., 2002; Mahieu et al., 2009), and dividing by the moment arm (MA) of the triceps surae muscle, which was individually measured by tape measure as the distance between the malleolus lateralis and the Achilles tendon at rest at neutral ankle position (90[degrees]) (Konrad and Tilp, 2014a; Konrad and Tilp, 2014b; Konrad et al., 2015).
When combining the EMG amplitudes from all the conditions (Figure 4), the dominant leg elicited greater normalized EMG activity compared to the non-dominant for each triceps surae muscle (P=0.021(1), F=3.292, power: 0.749) and in when the triceps surae EMG data were summated within leg (P=0.05(1), F=7.877, power: 0.799).
