Fotobiomodulação pré-jogo é eficaz na recuperação muscular em atletas profissionais de futebol, ensaio clínico, aleatorizado, placebo controlado, cross-over e triplo cego

Abstract

The present study aims to develop a research protocol, as well as a systematic review on therapeutic resources in muscle recovery and check the influence of the application of photobiomodulation pre game about recovery and muscle performance. A systematic review was conducted in the various databases in the years 2012 to 2017 and later applied the PEDro scale to assess the methodological quality of the studies selected and a randomised clinical trial, placebo-controlled and triple-blind. Participated in the clinical trial 30 professional athletes of the same football team, with an average age of 17 years, allocated in 2 groups. First was held the collection and measurement of the enzyme creatine kinase (CK), evaluation of the subjective perception of fatigue and then were allocated random way in the group, which has received application of active photobiomodulation and Group B, which received the application photobiomodulation placebo. During the match the athletes used a device called the global positioning system Global Position System (GPS) for further analysis of the variables corresponding to muscle performance. At the end of the match and after 48 hours the athletes were evaluated. A week after the first game, the relocation of the groups. As a result of the systematic review can be observed that articles with good methodological quality, obtained positive results: 40% of the studies with compression therapy; 28.5% of the studies with cryotherapy and 61.5% of the studies with photobiomodulation. With respect to the clinical trial showed that there was a reduction in the concentration of CK and improvement on subjective perception of tiredness after 48 h and difference in the number of shares at high speed and the total distance travelled between the groups. Thus it can be concluded that the photobiomodulation is the resource that presents better results in the literature regarding post workout muscle recovery, and photobiomodulation pre game is effective in improving muscle recovery (subjective perception of fatigue and concentration of Creatine Kinase p 0.05) and in some < parameters of muscle performance (number of shares in high and total distance travelled p < 0.05).
