Microtrauma

Microtrauma

Microtrauma refers to small, repetitive injuries or damage to muscles that occur at a rate faster than the body's ability to heal, often resulting from overuse or increased tension during lengthening muscle actions. These injuries are characterized by a transient disruption of sarcomeres and sarcolemma.From: Orthopaedic Biomechanics [2019], Whey protein supplementation does not accelerate recovery from a single bout of eccentric exercise [2021]

Disorders such as Carpal Tunnel Syndrome, Tendinitis, Tenosynovitis, DeQuervain’s Syndrome, and Thoracic Outlet Syndrome are just a few of the many dysfunctions that rarely result from single incidents. These problems tend to occur as a result of what has been termed “microtrauma.” Microtraumas are the result of frequent repetitions of motions and forces associated with workplace manipulative tasks. Many terms have been used to describe the syndromes that result from microtraumas. Terms such as repetitive motion injuries, repetitive strain injuries, cumulative trauma disorders, and even occupational overuse syndrome (the term currently used in New Zealand) attempt to emphasize the chronic nature of these “illnesses.”

Unaccustomed eccentric exercise results in microtrauma to myofibers and the surrounding extracellular matrix. This microtrauma, or muscle damage, is characterized by a transient disruption of sarcomeres and sarcolemma resulting from an increase of tension during lengthening muscle actions (Hyldahl & Hubal, 2014). This muscle damage is further exacerbated when exercise is performed with higher forces and a greater range of motion (Owens et al., 2019).
