These terms come from Latin words with similar meanings, ab-being the Latin prefix indicating ' away ', ad-indicating ' toward ', and ducere meaning ' to draw or pull '. [b] Abduction is a motion that pulls a structure or part away from the midline of the body, carried out by one or more abductor muscles.
The muscle redundancy problem is a result of more muscle vectors than dimensions in the task space. Muscles can only generate tension by pulling, not pushing. This results in many muscle force vectors in multiple directions rather than a push and pull in the same direction.
[5] Agonist muscles are also called prime movers since they produce most of the force, and control of an action. [6] Agonists cause a movement to occur through their own activation. [7] For example, the triceps brachii contracts, producing a shortening (concentric) contraction, during the up phase of a push-up (elbow extension).
Dorsiflexion of the foot: The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius. The range of motion for dorsiflexion indicated in the literature varies from 12.2 [8] to 18 [9] degrees. [10]
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be
Muscle strength is a result of three overlapping factors: physiological strength (muscle size, cross sectional area, available crossbridging, responses to training), neurological strength (how strong or weak is the signal that tells the muscle to contract), and mechanical strength (muscle's force angle on the lever, moment arm length, joint ...

This action causes them to push downwards with their feet and exert pressure, additionally to their bodyweight, onto the plate. [5] Dynamometer: A dynamometer is a device which involves two handles being pushed, pulled or squeezed together, or pushed or pulled apart, in order to register a reading. As the handles are typically extremely stiff ...
