For example, in a biceps curl the action of lowering the dumbbell back down from the lift is the eccentric phase of that exercise – as long as the dumbbell is lowered slowly rather than letting it drop (i.e., the biceps are in a state of contraction to control the rate of descent of the dumbbell).
The responses from these pathways are often termed medium or long latency stretch reflexes, because the time course is longer due to distance it needs to travel. [7] The central nervous system can influence the stretch reflex via the gamma motoneurons, which as described above control the sensitivity of the reflex.
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.

Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) [1] that examines the function of the C5 reflex arc and the C6 reflex arc. [2] The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon [ 3 ] as it passes through the cubital fossa .
Standing long jump performance is shown to be improved by swinging arms forward during the onset of the jump and back-and-forth during landing since the linear momentum of the body can be adjusted with the help of moving arms. [9] Use of arms in adjusting the rotational and linear momentum is also a common practice in somersaulting and gymnastics.
Athetosis is a symptom characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue. [1] Movements typical of athetosis are sometimes called athetoid movements.
