Localized Fatigue Changes Neuromuscular Activity during Lifting

Prolonged lifting may be associated with an incrase injury risk due to fatigued muscles being less capable of reacting to any perturbations that occur during a lift. Repetitive muscle use leads to reduced functional capacity, known as fatigue. In lower force tasks, fatigue is an ongoing process which may result in increased perceived effort and a reduction in the maximal force generating capacity of a muscle [1]. This study investigated the neuromuscular changes in a general and two local fatiguing lifting protocols.
