Deficits in these forces, for example, insufficient activation of rotator cuff /deltoid muscles or an over activation of the muscles, can lead to a narrowing of the sub-acromial space (Figure 3). Assist: obturator externus, Gluteus medius and minimus It is the main agonist muscle for this movement during the first 15 . The bench press is one of the most popular exercises in the fitness and sports community and is often used as a measuring stick for evaluating upper body strength (Robbins 2012; Bianco, Paoli & Palma 2014). Lower trapezius: along with the serratus anterior muscle, they are a primary upward rotators of the scapula. The athlete contracts the antagonist isometrically against resistance provided by the therapist for 6-10 seconds. Fitness Muscles that have their origins in the anterior (front of) shoulder joint tend to flex the arm (pectoralis major, coracobrachialis and anterior fibres of the deltoid). sartorius . > Aim to perform the exercise through a full range of motion unless mobility/flexibility deficits restrict motion or pain/pinching sensations are felt in the shoulder region. Erector spinae spinalis Agonist Muscles (prime movers); the main muscles that cause movement at a joint Antagonist Muscles oppose and cause the opposite movement of agonist muscles Muscles work in. Resistance training exercises can promote neural and structural modifications to the shoulder complex[23][24] and can increase the sensory, biomechanical, and motor-processing patterns[25] (such as to the cervico-thoracic spine, the shoulder complex and the upper extremities as a whole). Teres major has the same action of latissimus dorsi of adduction, extension, internal rotation. extensor hallucis longus However, this position may place the shoulder in a vulnerable position (Green, 2007). > Anterior Deltoid (front of shoulder muscle). Blood supply to the Supraspinatus is the suprascapular artery. agonist: TFL & gluteus medius brachioradialis, extensor carpi radialis longus From Figure 1 and 2, we can consider the deltoid and rotator cuff muscles as a collective force coupling for the movements associated with the glenohumeral joint. Presence of tight muscles due to postural stress and neurological hyperactivity (such as the presence of trigger points). Similarly, abduction and adduction at the wrist moves the hand away from or toward the midline of the body. Lam, Jonathan; Burdoni, Bruno. Continue with Recommended Cookies.
