Efeitos da terapia de fotobiomodulação aguda sobre desempenho de testes específicos em atletas amadoras de futsal feminino

Abstract

The acute improvement of performance after photobiomodulation therapy (PBMT) has been reported in different types of exercises. However, the effect on high-intensity and intermittent exercise is unknown. To evaluate the effect of prior acute application of PBMT on high-intensity and intermittent exercise performance and physiological/perceptual indicators in amateur female futsal players. Thirteen female futsal players (24.1 ± 3.7 years, body (kg) = 63.6 ± 8.0, height (cm) = 1.61 ± 0.04, IMC = 24.3 ± 3.2 and percentage of fat (%) = 27.9 ± 4.4) cross-over and randomly on different days received either PBMT or SHAM and performed the CMJ, Illinois agility and YYIR1 tests, as well as responding to recovery status, perceived exertion, heart rate monitoring, and concentration of lactate analyzed. The distance walked on the YYIR1 did not differ (p = 0.93) between PBTM (353.8 ± 97.7m) and SHAM (350.8 ± 88.1m), as well as pre-CMJ height (18.5 ± 1.7 SHAM, 19.3 ± 2.8 PBMT) and post (18.9 ± 1.9 SHAM, 19.3 ± 3.0 PBMT) and between the best time, average and total time in the agility test, the variables intensity (lactate, RPE and HR) and acute recovery were also not statistically different between the two conditions The acute application of PBMT prior to exercises does not influence specific high-intensity and intermittent exercise performance, neither physiological and perceptual intensity in amateur female futsal players.
