The effect of tackling on shoulder joint positioning . Many muscles are involved in the joint actions listed above. However, because of the vast range of motion of the shoulder complex (the most mobile joint of the human body), dynamic stabilizers are crucial for a strong sense of neuromuscular control throughout all movements and activities involving the upper extremities. During flexing of the forearm, the triceps brachii is the antagonist muscle, resisting the movement of the forearm up towards the shoulder. Flexor Hall longus From Figure 2 we can see three of the RC muscles (teres minor, subscapularis, infraspinatus), in relation to their anatomical position and their muscle fiber direction from origin to insertion. Medicine & Science in Sports & Exercise, 21(4), 450-462.Fees, M., Decker T., Snyder-Mackler, L., Axe ,MJ. The glenohumeral jointcommonly referred to as the shoulder jointconsists of the attachment of the humerus bone to the scapula. Hip flexors. > Inhale during the lowering (eccentric) phase of the exercise. The moveable end of the muscle that attaches to the bone being pulled is called the muscles insertion, and the end of the muscle attached to a fixed (stabilized) bone is called the origin. antagonist: erector spinae, gluteus maximus traps (neck), subscapularis And as it attaches to scapula proximally, humerus distally, for effective adduction and extension it acts to pull humerus to the scapula (stable part), and hence this movement associated with scapula downward rotation and retraction. Such muscles to consider are the serratus anterior, serratus posterior, the trapezius (upper / middle / lower), the rhomboids, teres major, the levator scapulae, the latissimus dorsi and the flexibility and mobility of the thoracolumbar fascia.
