Effect of Whole-body Photobiomodulation on Muscular Performance Enhancement.
Sponsor: Universidade Federal de Sao Carlos
Summary
Introduction: Photobiomodulation therapy (PBMT) is based on the emission of light ranging from red to near-infrared spectra by different devices based on diode lasers or light-emitting diodes. These devices emitting different wavelengths can increase mitochondrial activity and energy synthesis (ATP - adenosine triphosphate) that in turn can help to prevent muscle damage, decrease muscle fatigue and enhance muscle performance. Thus, PBMT can be a promising therapeutic resource in the sports field. Objectives: The aim of this study is to verify the effect of PBMT on the muscle performance and prevention of muscle damage and delayed onset muscle soreness (DOMS) in professional soccer players submitted to a muscle damage protocol. Methodology: The present study is a randomized sham-controlled clinical trial following the CONSORT guidelines.

Interventions
Muscle damage protocol training
The adopted protocol of muscle damage will follow the recommendations from American College of Sports Medicine (ACSM) in 2009 for trained individuals. It consists of 8-12 repetitions above 70% of 1 Repetition Maximum (1RM) with 1 minute of rest between sets and 2 minutes between exercises. The protocol will be composed as follows: 3 sets of 10 repetitions for each exercise, with an emphasis on producing microlesions in the muscle tissue (muscle damage protocol).
Photobiomodulation therapy (PBMT)
PBMT will be administered using a whole-body irradiation system (Joovv Elite System, Joovv Inc.), consisting of 6 panels with 76 red LEDs (660 ± 10 nm) and 74 infrared LEDs (850 ± 10 nm), totaling 900 LEDs covering an area of 12,193 cm². Athletes will stand 20 cm in front of the device, wearing only swim shorts to expose their thigh muscles and other body areas to the light. The total irradiation time will be 20 minutes, with 10 minutes (600 seconds) of irradiation for the anterior region and another 10 minutes (600 seconds) for the posterior region. The active PBMT dose applied in each region (anterior or posterior) will be 48.97 J/cm², with an irradiance of 81.62 milliwatt (mW)/cm². The PBMT Sham dose applied in each region (anterior or posterior) will be 0 J/cm², with an irradiance of 0 mW/cm².
