Abstract:
BACKGROUND:Skeletal muscle fiber damage that is induced by prolonged or high-intensity exercise directly cause muscle injury. OBJECTIVE:To propose the existence of a relationship between delayed onset muscle soreness and muscle satel ite cel s after skeletal muscle injury from the objective reality. METHODS:A retrieval of CNKI and PubMed databases was done for relevant literature published from February 1961 to February 2015 using the keywords of“delayed onset muscle soreness;skeletal muscle injury;satel ite cel s, skeletal muscle;myogenic regulatory factors”in Chinese and English, respectively. Final y, 59 articles were included to explore the mechanism of skeletal muscle injury accompanied by delayed onset muscle pain. RESULTS AND CONCLUSION:Skeletal muscle micro-injury mainly refers to ultrastructural destroy and metabolic disorders, involving muscle cel membrane, cytoskeleton, sarcomere and mitochondria, thereby leading to skeletal muscle contraction dysfunction that is often accompanied with delayed onset muscle soreness. Eccentric exercise can cause the severest microdamage to the skeletal muscle fibers. The occurrence of delayed onset muscle soreness can stimulate the secretion of growth factors from skeletal muscle satel ite cel s to a certain extent, and the time series of delayed onset muscle soreness triggered by sustained high-intensity eccentric exercise has a certain correlation with the time series of the proliferation of skeletal muscle satel ite cel s.
