Recording set-up per Konrad 2005: Inter-electrode distance 2 cm (centre to centre) · Skin impedance 5–50 kΩ, aim low · Band-pass 10–500 Hz · Sampling ≥ 1000 Hz · no notch filter

S1 M. Triceps Brachii Caput Longum Triceps Brachii (Long Head) · left · Upper Arm SENIAM

Position: 50% on line between posterior crest of the acromion and olecranon, 2 finger widths medial to the line
Orientation: Parallel to line posterior crest of the acromion–olecranon
Signal check: Extend the forearm against resistance.
Crosstalk from: biceps brachii · posterior and middle deltoid
MVC test: Same set-up as the biceps test: seated or kneeling, elbow at about 90°, upper arm slightly abducted.
Fixation: Elbow and trunk fixed as for the biceps.
Resistance: Rigid resistance from above on the wrist (fixed bar or manual), elbow extension against it.
