Functions and Movement of the Elbow Muscles
Functions:
Biceps
The biceps are a 2 joint muscle – shoulder and elbow joints; it is weak in any actions at the shoulder joint and is the most powerful flexor of the elbow joint. Flexion of the forearm, known as ‘curling’ with a barbell in the hands is an excellent exercise to develop the bicep brachii.
Brachialis
The brachialis is used along with other flexor muscles , whether in pronation or supination. It pulls on the ulna, which does not rotate, thus making this muscle the only pure flexor of this joint.
Triceps:
Typical action of the triceps is shown in press-ups when there is powerful extention of the elbow. It is used in any pushing movements. Pressing a barbell upward with weights is an excellent exercise to develop this muscle
