Effects of Phototherapy by Light-emitting Diode Therapy (LEDT) on Clinical, Biochemical and Biomechanical of Muscle Performance in Athletes

Not Applicable

Completed

• Conditions: Athlete
• Interventions: Device: Light-emitting diode therapy; Device: Placebo light-emitting diode therapy

• Registration Number: NCT01770977
• Lead Sponsor: Universidade Federal de Sao Carlos

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.
