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

January 15, 2013 updated by: Cleber Ferraresi, Universidade Federal de Sao Carlos
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.
