Neuromuscular fatigue is defined as “transient decrease in muscular performance usually seen as a failure to maintain or develop a certain expected force or power.” Fatigue can be peripheral, originating from the muscle fibers or central, originating from a reduction in motor unit activation and/or fire rate.
Neuromuscular fatigue can be evaluated using electromyography, which is a technique that measures the electrical activity of muscles during various activities, including exercise and sport (and is commonly used in medicine for diagnosing nerve and muscle diseases like lou gehrig’s disease).
It is known that folks with different training background affects neuromuscular fatigue, such as endurance athletes, sprinters, martial arts athletes, weight lifters.
What is not known is how it affects strength tasks such as squats and other resistance training exercises.
The authors of this study sought to assess max number of repetitions and total weight lifted, as well as neuromuscular activity in folks with different training backgrounds.
