Abstract

Recent studies have used the phototherapy by low-level laser therapy (LLLT) to improvement muscle performance in humans, decreasing fatigue and increasing muscle torque. Aligned to these effects, LLLT possibly promotes structural changes in muscle tissue such as transition between fiber types, increased vascularization, mitochondrial density and satellite cells, pointing as some of the possible mechanisms that explain the good results of this therapy. Thus we have the prospect of representing the effects of phototherapy by LLLT on human muscle performance in strength exercises, investigating mainly adaptations on indicators of muscle performance, immunohistochemical and genetic. To achieve these objectives, the randomized clinical trial (FAPESP 2010/07194-7 process) is being performed. This study involves 30 volunteers (young and healthy men) who underwent physical strength training in leg press associated with LLLT. In addition for signaling pathways of genes related to hypertrophy and atrophy, satellite cells and mitochondrial biogenesis, now we have new perspective to analyze the whole human transcriptome (microarray analysis) in association with possible structural changes of muscle fibers (immunohistochemical analysis). This cooperative study between the UFSCar and Harvard Medical School will allow the understanding of all adjustments described above, which are extremely important to elucidate some mechanisms of action of the LLLT on muscle performance as reported in previous studies. Also, this study represents a major advance in knowledge in biotechnology, physiotherapy and sports medicine. (AU)
