Comparação entre a terapia por fotobiomodulação e a crioimersão na recuperação pós jogo em atletas de alto rendimento de futebol: análise de marcadores bioquímicos de recuperação e estresse oxidativo muscular

Abstract

High-performance soccer requires great physical ability of the athlete. The type of metabolism, motor actions with changes of direction, eccentric contractions, associated to the short periods of recovery between the games, favor the risk of injuries, reducing homeostasis and athletic performance. Therefore, strategies and recovery methods are important in minimizing fatigue and oxidative stress in high-level athletes. Cold Water Immersion (CWI) is widely used in soccer with good efficacy in attenuating some markers of muscle damage, such as creatine kinase (CK), lactate dehydrogenase (LDH) and late muscle pain. There are many studies on photobiomodulation therapy (PBMT) in the repair of injured tissues and also on muscle recovery. Clinical studies point to the efficacy of PBMT in attenuating biochemical markers on oxidative stress, with thiobarbituric acid (TBARS) as an oxidizing enzyme and superoxide dismutase (SOD), and catalase (CAT) as antioxidant enzymes. The present study is a blinded randomized clinical trial for the evaluators that promoted the analysis of the TBARS, SOD and CAT oxygen reactive species in addition to the enzymes for CK and LDH muscle damage in the comparison between the two recovery techniques after games of soccer, through cross-over of the sample of 12 athletes soccer players between 16 and 17 years of a soccer club of São Paulo. PBMT was shown to be more effective in decreasing markers of CK, LDH and TBARS oxidant enzyme damage and increased antioxidant enzymes SOD and CAT compared to CWI in immediate and late recovery 48 hours after soccer play in high-performance athletes.
