When the hip is extended, such as standing, the piriformis rotates the thigh outwards. When the hip is flexed , such as sitting, the piriformis abducts the hip (spreading the legs). The piriformis originates at the anterior surface of the sacrum , passes through the greater sciatic foramen , and inserts at the greater trochanter .
Perform the bicep curl, but with one arm at a time instead of curling both weights up together. Curl the right arm up first, then lower it down. Then curl the left arm up and lower it down.
Counterintuitively, continued exercise may temporarily suppress the soreness. Exercise increases pain thresholds and pain tolerance. This effect, called exercise-induced analgesia, is known to occur in endurance training (running, cycling, swimming), but little is known about whether it also occurs in resistance training. There are claims in ...
Typically, a bicep curl begins with the arm fully extended with a supinated (palms facing up) grip on a weight. A full repetition consists of bending or "curling" the elbow until it is fully flexed, then slowly lowering the weight to the starting position. The torso should remain upright instead of swinging back and forth, as doing so transfers ...
Manipulation of the shoulder under general anesthesia to break up the adhesions is sometimes used. Because adhesive capsulitis is a condition that produces stiffness and causes the capsule of the glenohumeral joint to become thickened and progressively contract, it is important to exercise regularly to increase the range of motion and decrease ...
Bicipital tenosynovitis is tendinitis or inflammation of the tendon and sheath lining of the biceps muscle. It is often the result of many years of small tears or other degenerative changes in the tendon first manifesting in middle age, but can be due to a sudden injury.
Dead arm syndrome starts with repetitive motion and forces on the posterior capsule of the shoulder. The posterior capsule is a band of fibrous tissue that interconnects with tendons of the rotator cuff of the shoulder. Four muscles and their tendons make up the rotator cuff. They cover the outside of the shoulder to hold, protect and move the ...
The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
