Summary

In recent years, photobiomodulation has been studied as a means of increasing muscle performance in athletes and healthy individuals. This is possible due to the physiological changes that photobiomodulation therapy can promote. Moreover, given a large number of existing studies on the subject, some directions for future research have been established. For example, future research was established, the relationship between power and time because with high power, it will achieve the same energy with shorter application times. However, irradiation may not be offered for the minimum recommended time. Therefore, this study aims to compare different powers and, consequently, different application times for muscle performance in healthy individuals. For this, 42 participants will be recruited, males between 18 to 40 years old, without recent musculoskeletal injury or cardiorespiratory problems. The participants will participate in 3 evaluations containing functional and physiological variables and ten training sessions of lower limbs with previous photobiomodulation therapy application, comparing devices with a power of 0.864W and 1.864W. 0.864W and 1.2W. Lower limbs training will be composed of stiff and squat exercises twice a week, for five weeks. In the pre- and post-intervention evaluations, the following parameters will be evaluated isokinetic apparatus, body composition, and functionality of the vertical jump. For data analysis, we will use a normality test to verify the distribution and statistical tests will be used for intra and intra and intergroup comparisons, considering two factors in the comparisons time and group. A significance level of 5% will be adopted.
