Effects of Photobiomodulation Therapy Combined With Static Magnetic Field in CrossFit® Athletes

A cluster with 20 diodes, manufactured by Multi Radiance Medical® (Solon, OH, USA), will be used: 4 diodes of 905 nm (1.25 average power, 50 W of peak power for each diode), 8 diodes of 850 nm (40 mW of average power for each diode) and 4 diodes of 633 nm (25 mW average power for each diode). Effective PBMT/sMF will be applied in direct contact with the skin and light pressure in: 4 sites in the knee extensor/hip flexor muscles, 3 sites in the knee flexor/hip extensor muscles and 1 site in the plantar flexor muscles. The effective PBMT/sMF will be applied to both lower limbs. The dose used for applications will be approximately 270 J for knee extensors/hip flexors, 180 J for knee flexors/hip extensors, and 60 J for plantar flexors.

A cluster manufactured by Multi Radiance Medical® (Solon, OH, USA) with 20 diodes will be used: Placebo PBMT/sMF will be applied in direct contact with the skin and light pressure in: 4 sites in the knee extensor/hip flexor muscles, 3 sites in the knee flexor/hip extensor muscles and 1 site in the plantar flexor muscles. The placebo PBMT/sMF will be applied to both lower limbs. The dose used for applications will be approximately 0 J per diode. The sounds and signals emitted from the device as well as the information displayed on the screen will be identical, regardless of the type of treatment (active or placebo).
