Soreness can theoretically be avoided by limiting exercise to concentric and isometric contractions, [11]: 112 but eccentric contractions in some muscles are normally unavoidable during exercise, especially when muscles are fatigued.
The definition of eccentric contraction is almost the exact definition of muscle strengthening. Perceived muscle damage: There is a stipulation regarding eccentric contractions in that they actually cause muscle damage and injury. Eccentric contraction may result in delayed onset muscle soreness however; the contraction itself does not cause ...
Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]
What is muscle soreness? Muscle soreness is pain, discomfort, tenderness, and/or stiffness caused by micro-tears to muscle fibers, explains Carson Gantzer, M.S., C.S.C.S., performance physiologist ...
Muscle soreness may refer to: Acute muscle soreness (AMS), which appears during or immediately after exercise and lasts up to 24 hours.
That muscle soreness, specifically the delayed-onset muscle soreness (DOMS) you feel a day or two after a hard workout, is the result of small tears in your tissues, according to a study published ...
The resultant ischemia leads to necrosis (death of tissue) of the muscles and nerves. The process can begin with swelling of the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and/or the peroneus tertius muscles in response to strong eccentric contractions sufficient to produce postexercise soreness.

There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing. [citation needed]
