Brief summary: Light-emitting diode Therapy (LEDT) has been used to improve human muscle performance in experimental models and human researches. Now, the investigators used LEDT to increase muscle performance of professional athletes with high performance.

Detailed description: The study assessed muscle performance by vertical jump (height of jump and muscle power); creatine kinase; lactate; metabolism by resonance nuclear magnetic in urine; oxygen uptake (VO2) and its onset kinetic response.

Eligibility criteria: Inclusion Criteria:

* professional athletes aged between 14 and 16 years;
* professional athletes aged between 18 and 28 years

Exclusion Criteria:

* previous injury to the femoral quadriceps or hamstring muscles,
* osseous or articular disorder in the lower limbs,
* cardiovascular system disorders,
* systemic disease.
