Abstract

Uvod: Živčno-mišična električna stimulacija (angl. neuromuscolar electrical stimulation – NMES) stimulira mišična in/ali živčna vlakna in s tem povzroča mišično aktivacijo. Električni dražljaj je apliciran prek kože na mišično motorično točko s pomočjo elektrod. NMES močno vpliva na mišični metabolizem in povzroča velike fiziološke adaptacije. Tehnika se uporablja v športu za izboljšanje mišične zmogljivosti in v medicinski rehabilitaciji za izboljšanje mišične zmogljivosti po poškodbi ali operaciji. Čeprav so živčno-mišične adaptacije pridobljene z NMES v zdravih in neoživčenih mišicah velike, niso večje kot adaptacije pridobljene s hoteno mišično kontrakcijo. Določene raziskave navajajo, da dolgotrajna kombinacija NMES in hotene mišične kontrakcije pri zdravih posameznikih povzročajo boljše živčno-mišične adaptacije kot pa samo vadba z NMES. Namen: Namen diplomske naloge je bilo ugotoviti učinke vadbe za izboljšanje mišične zmogljivosti, v kombinaciji z NMES, na mišično zmogljivost zdravih posameznikov. Metode dela: Kot metoda dela je bil uporabljen sistematičen pregled literature. V pregled so bile vključene raziskave, ki so bile izbrane na podlagi postavljenih kriterijev. Rezultati: V pregled literature je bilo vključenih osem randomiziranih kontroliranih raziskav. V vseh pregledanih raziskavah so avtorji ugotovili, da vadba za izboljšanje mišične zmogljivosti, v kombinaciji z NMES, pripomore k izboljšanju posameznih komponent mišične zmogljivosti. Razprava in sklep: Vadba za izboljšanje mišične zmogljivosti, v kombinaciji z NMES, pripomore k izboljšanju eksplozivne moči in največje hotene izometrične kontrakcije (angl. maximum voluntary isometric contraction – MVIC). Za izboljšanje eksplozivnosti moči je potrebna kombinacija pliometrične vadbe z visokimi frekvencami stimuliranja, medtem ko izboljšanje MVIC dosežemo tako s kombinacijo vadbe proti uporu in NMES kot tudi s kombinacijo pliometrične vadbe in NMES.

Secondary title: Effects of performance training with superimposed neuromuscolar [!] electrical stimulation on muscle performance in healthy subjects - systematic literature review
Secondary abstract: 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.
