Biceps isometric strength
elbow flexion angulation
Participants stood on top of the machine. The foot opposite to the arm executing the gesture was placed parallel to the cord, while the other foot was placed behind. Both feet were placed on the line marked by the width of the shoulders. The knees were semi-flexed at approximately 15° (0° = full knee extension), the back straight, the shoulders aligned, and the gaze always straight ahead. The elbow flexion angulation was 45° or 90° (0° = full elbow extension).
