Summary

Background: Photobiomodulation has been explored for years, with wide clinical use for wound healing and analgesia in varied orthopedic conditions, but the number of research and clinical use has increased during the last decade. Furthermore, considering the performance, the current literature is conflicting and restricted, with divergences in wavelength, power and energy density applied. Therefore, analyze different doses for a answer in short and long time, associated with capacities of strength, fatigue resistance and functional performance of handball players and healthy individuals becomes necessary. Objective: To analyze the effects of the application of LED photobiomodulation on the capacities of strength, functional efficiency, temperature and fatigue resistance of handball players and healthy individuals. Method: The study sample will be composed of 56 male individuals randomly allocated into four groups: LED 50J (G-50J), LED 240J (G-240J), LED 50-240J (G-50-240J) - progressive dose and Sham (G-S). The volunteers will be submitted to an evaluation of muscle performance and functional performance, metabolic, and physiological evaluation. After initial tests, in five consecutive weeks, the LEDT (940nm - infrared) will be applied to the quadriceps femoris muscle and hamstrings, bilaterally, associated with a muscle strength protocol. After 24 hours of the last application TLED, the tests will be repeated. Seven days after the last intervention will be performed a follow-up. For analysis, normality tests will be used to verify the distribution and adequate statistical tests for the appropriate intra and intergroup comparisons, being considered two factors in the comparisons, time, and group. A significance level of 5% will be adopted.

Photobiomodulation

An LED blanket with 267 infrared lamps with predetermined doses will be used, given a wavelength of 940nm, for 5 weeks, it will be applied by all extension of the quadriceps and hamstrings bilaterally, just before the force training protocol for the groups intervention or simulation for the sham group. Photochemical or photophysical effects are expected from its application.
