Myoelectrical manifestations of localized muscular fatigue in humans.

摘要: Fatigue may be described as the decline in ability of an individual to maintain a level performance. However, issue fatigue man is complex due various physiological and psychological phenomena which contribute it. This article limited discussion appertaining that associated with changes processes, specifically caused by sustained or repeated muscle contractions. It has long been known during contractions frequency spectrum myoelectric signal undergoes shift. Recently, several analyses investigations have reported on applicability this phenomenon for supplying objective noninvasive measurements localized fatigue. The essence results pertinent publications are discussed emphasis relationship between spectral shift signal, conduction velocity fibers, pH interstitial fluid blood flow within muscle.
