Effetto della fotobiomodulazione di tutto il corpo sul miglioramento delle prestazioni muscolari. (WBPME)
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.

Descrizione dettagliata
Participants will be allocated into 3 balanced randomized groups, as follows: 1) PBMT post muscle damage protocol (PBMT-post); 2) PBMT pre (PBMT-pre) and 3) PBMT placebo (PBMT-sham). All groups will be submitted to a) anamnesis; b) measurement of blood levels of creatine phosphokinase (CK); c) delayed onset muscle soreness (DOMS); d) muscle performance tests (Squat Jump test (SJ) and Counter Movement Jump (CMJ)); e) dynamometry of the knee extensor muscles. Whole body PBMT will be applied according to the groups, during 10 min (sham or effective), with an effective dose of 48.97 J/cm2 and irradiance of 81.62 mW/cm2. Muscle damage protocol will consist of 8 exercises for lower limb muscles, with 3 sets of 10 repetitions each, 1 minute of rest between sets, and 2 minutes of rest between exercises. Next, participants will be evaluated for levels of CK, DOMS and muscle performance (SJ, CMJ, dynamometry) at 24, 48 and 72 hours after muscle damage protocol. Data will be analyzed and compared between groups with a significance level of 5%.

Sperimentale: PBMT post muscle damage protocol (PBMT-post)
Group submitted to pre-exercise Sham (placebo) photobiomodulation therapy (PBMT), and post-exercise active 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 mW/cm². |
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).

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. |
