Introduction: Neuromuscular electrical stimulation (NMES) stimulates muscle and/or nerve fibers and with it causes muscular activation. Electrical stimulus is applied through the skin on to the muscle motor point with the help of the electrodes. NMES impacts strongly on the muscular metabolism and causes great physiological adaptations. The technique is used in sports, for improving muscular performance, and in medical rehabilitation, for improving muscular performance after injuries and surgeries. Even though the neuromuscular adaptations gained by the NMES are big in healthy and disused muscles, they are not bigger than the adaptations gained by voluntary muscle contraction. Some research suggests, that the long-term combination of NMES and voluntary muscle contraction, in healthy subjects, causes better neuromuscular adaptations, then NMES alone. Purpose: The purpose of this bachelor’s degree was to determine the effects of performance training with superimposed NMES performance in healthy subjects. Methods: The method used in this paper was a systematical review of literature. Research papers included in the review were selected based on a set of criteria. Results: Eight randomized controlled trials were included in the literature review. In all reviewed trials, it was found out that performance training with superimposed NMES helps in improving individual components of muscle performance. Discussion and conclusion: Performance training with superimposed NMES helps in improving explosive power and maximal voluntary isometric muscle contraction (MVIC). For explosive power improvement, the combination of plyometric training with high frequency of stimulation is needed, while MVIC improvement is achieved, with both resistance training superimposed with NMES and plyometric training superimposed with NMES.
