Sponsor's own description

Athletes experience an exhaustive routine of training, associated with the reduced time of rest, facilitates the appearance of muscle fatigue, which increases the risk of muscle injuries, especially during the execution of the jump. Low Level Lasertherapy is a technique that has been increasingly improved due to the physiological effects it provides in the muscle recovery process. However, there is still a lack of studies focused on the use of this technique in functional improvement, especially in jumping sports. Objectives: To evaluate the immediate and short-term effects of low-level laser on the functional performance of lower limbs of jumping athletes and to evaluate the short-term effects of low-level laser on the activation of the gluteus medius and quadriceps muscles. Methods: This is a brief, double-blind, randomized, placebo-controlled clinical trial. Will be recruited 24 handball and volleyball players aged between 18 to 35 years. The primary outcome of our study is functional performance (modified hop test and modified SEBT), and as a secondary outcome (level of electromyographic activity). After the baseline assessments, the athletes will be randomized and allocated into two groups: Intervention Group (IG, n=12) and Control Group (CG, n=12) and submitted to a fatigue protocol, followed by laser therapy or placebo.
