What to Do When Your Shoulders Refuse to Grow and It's a Problem for Many Fitness Enthusiasts

The muscles of the shoulder girdle are crucial for individuals aiming for an aesthetic appearance. What can cause difficulties during the development of the muscles of the shoulder girdle, and what are the solutions? Physical exercises lead to a series of processes in the body, resulting in muscle growth. The main mechanisms for these changes include: - mechanical stress and increased muscle tension, - metabolic stress and local growth factors. The former is caused by heavy loads applied in multi-joint exercises, while the latter mechanism is primarily due to isolated exercises and prolonged time under tension. High muscle tension causes a series of changes and enhances the effect of the hormonal system (release of the strongest anabolic hormones in the body). Testosterone, growth hormone, insulin, IGF-1, and other hormones cause muscles to grow. Focusing on this mechanism is essential when the goal is muscle development.

Training parameters such as the number of sets, repetitions, tempo (tempo and repetition count make up the time under tension - TUT) and rest time mainly depend on the goal, muscle fiber morphology, and type of exercise. Research shows that the limb muscles have a similar number of muscle fibers with only slight variations between individual acts. With this information, training parameters can be selected appropriately. There are two mechanisms that contribute to muscle growth: muscle tension and metabolic stress. Muscle tension increases with increasing load, and the load that can be lifted is greater if someone is stronger. To increase strength in muscles with the same number of muscle fibers, 5 sets of 4 repetitions or 3 sets of 6 repetitions should be performed. The tempo for exercises focused on strength development should be relatively fast - the total time under tension of about 20 seconds, so the tempo could be 2 0 1 0, 1 0 1 0 with a rest time of more than 120 seconds. It is important to apply these training parameters to exercises where a high load can be lifted, such as push-ups or landmine press. To induce metabolic stress, 3 sets of 13 repetitions or 4 sets of 10 repetitions should be performed with a time under tension of up to 50 seconds, which corresponds to a tempo of 3 0 1 0, 4 0 1 0 with a rest time of 30-60 seconds. For these parameters, isolated exercises such as curls or dumbbell presses are highly suitable.

During training of the upper extremity muscles, many mistakes can be observed, the first of which is the incorrect positioning of the elbows and wrists when performing the pressing movement.

Jpg When it comes to overhead press, there are several ways to perform this exercise. The best option is the one that least strains the structures of the shoulder joint, especially the supraspinatus muscle. This is the version where the hands are positioned in external rotation (thumb slightly pointed up) - the movement pattern of the exercise is demonstrated in the following video.

Superior intersecting disorder is a disturbance of the bone and muscular system, where some muscles exhibit excessive tension while others are weakened, resulting in an increase and disruption in the natural curvature of the spine, consequently altering body posture.

The intricate shoulder joint system comprises three smaller joints: the shoulder joint, the sternoclavicular joint, and the acromioclavicular joint, as well as rib-scapula connections. The shoulder joint has the greatest range of motion of all joints, but its construction is not very stable. To ensure stability, the body develops certain structures called local stabilizers, which are mainly the muscles of the rotator cuff, consisting of the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. If these muscles are weakened, the shoulder muscles must generate more force, both for shoulder joint movement and its stabilization. To determine if there is a problem with the strength or endurance of these muscles, specialized tests can be performed.
