Abstract
Uvod: Obsevanje z laserjem ima pozitivne učinke na mišično tkivo z vidika regeneracije skeletnih mišic, aktivira satelitske celice skeletnih mišic, povečuje njihovo proliferacijo in zavira diferenciacijo, poveča mišični metabolizem, zmanjša koncentracijo laktata v krvi ter poveča presek mišičnih vlaken in gostoto mitohondrijev. Nekateri rezultati študij kažejo, da nizko intenzivni laser zmanjša možnost nastanka mišičnih poškodb in upočasni mišično utrudljivost. Namen: Namen diplomskega dela je na podlagi pregleda strokovne in znanstvene literature predstaviti učinke obsevanja z nizko intenzivnim laserjem na zmogljivost mišic spodnjih udov. Metode dela: Literatura je bila pridobljena s pomočjo naslednjih podatkovnih zbirk: PubMed, PEDro in Springer Link. V pregled literature so bile vključene v celoti dostopne raziskave v angleškem jeziku v obdobju zadnjih 10 let, kjer so sodelovali zdravi preiskovanci. Rezultati: V pregled literature je bilo vključenih osem randomiziranih kontrolnih raziskav. V šestih raziskavah so ugotavljali učinke laserske terapije nizke intenzitete v kombinaciji z vadbo za vzdržljivost in v dveh raziskavah z vadbo za jakost. Rezultati vključenih raziskav so pokazali, da je prišlo do izboljšanja mišične zmogljivosti v vseh skupinah, ne glede na parametre laserske terapije in raznolikosti izvajanja vadbe. Razprava in zaključek: V kar sedmih raziskavah so dokazali statistično pomembno izboljšanje mišične zmogljivosti, ki je bilo opazno pri ponovitvenemu maksimumu in največji hoteni izometrični kontrakciji. Zaradi majhnega števila pregledanih raziskav in raznolikosti optimalnih parametrov ne moremo podati zanesljivih zaključkov, ali laserska terapija nizke intenzitete izboljša mišično zmogljivost. V prihodnosti bo potrebno izvesti več kvalitetnih kontrolnih raziskav, da bi lahko potrdili učinke laserske terapije nizke intezitete.

Title:Effects of low-intensive laser therapy on muscle performance of lower limb : literature review
Abstract:
Introduction: Laser radiation has positive effects on muscle tissue in terms of skeletal muscle regeneration; it activates skeletal muscle satellite cells, enhances their proliferation and inhibits differentiation, increases muscle metabolism, reduces post exercise blood lactate levels, increases cross-section of muscle fibres and mitochondrial density. Some results of studies indicate that a low-intensity laser reduces muscle damages and slows down muscle fatigue. Purpose: The purpose of the thesis was to present the effects of radiation with low intensity laser on muscle performance of the lower limb, on the basis of a review of professional and scientific literature. Methods: Literature was obtained using following databases: PubMed, PEDro and Springer Link. The review included researches in English language from the last 10 years. Results: The literature review included 8 randomized control studies. Six studies have identified the effect of low intensity laser therapy in combination with endurance exercise and two studies in combination with strength training. The results of the included studies have shown that there has been an improvement in muscle performance in all groups, regardless of the parameters of laser therapy and the variety of exercise. Discussion and conclusion: In seven researches there has been confirmed statistically important muscle improvement, which was noticeable in repetition maximum and maximum voluntary isometric contraction. Due to low number of researches and variety of optimal parameters we cannot conclude with certainty if low intensity laser therapy improves muscle performance. In the future more quality control researches should be done in order to confirm the effects of low-intensity laser therapy.

Keywords:laser therapy, low-intensive laser, muscle performance, exercise to improve muscle performance
