Objective: To update the latest outcomes on the use of near infrared technology in sport medicine and the central nervous system. Materials and Methods: A review and analysis of present research on the achievements of Near infrared light emitting diode use in sport medicine and neuroscience was conducted. During the review medical books, journals, anecdotes, social networks, and magazines of current literature on the uses, and instruments, of Near Infrared light emitting diode were analyzed. Discussion: The update on Near infrared light emitting diode oxygen spectroscopy and the effects on wound healing, inflammation, neurodegenerative disease, and pain are presented. Current literature does not support major clinical outcome difference between Near infrared light emitting diode laser treatment and Near infrared light emitting diode treatment. The use of the Near infrared light emitting diode has significant differences regarding equipment location, economic benefits, availability, and the opportunity of immediate care and repetition of use at home by the patient's family.
