Introduction and objective:
Aspects of muscle function (AoMF), such as strength, power, torque, local muscle endurance, and hypertrophy, have a major influence on physical fitness and functional performance. Photobiomodulation (PBM) has been used to improve performance in resistance exercise. The aim of this study was to identify the effects of PBM on the AOMF, and to verify the dosimetric parameters of the intervention.

Review methods:
The review followed the PRISMA guidelines. The databases used were PubMed, Web of Science, Scopus, Embase, Lilacs, Cochrane, LIVIVO, CINAHL, PeDro, Open Grey, Google Scholar, and CAPES Thesis and Dissertation. To be included, the studies had to be applied to healthy humans of either grender or age group, report the effects of PBM, present variables of muscle strength, torque, power, and hypertrophy.

Brief description of the state of knowledge:
The database search resulted in 3,092 records, as well as additional records identified through other sources – PEDro with 793 records and Capes Thesis and Dissertation with 1,492 records, a total of 5,377 records. After removing duplicates, 4,796 records remained. After reading the titles and abstracts, 56 records remained, which were read in full and evaluated according to the review criteria. 29 studies were eligible for inclusion based on the inclusion and exclusion criteria of this scoping review.

It was possible to observe similarities in the studies, especially the moment of application being the pre-exertion moment, the dose of energy applied per point was 30J, and the wavelength – 808–810nm.
