About

Muscle performance is largely influenced by modulations in gene expressions of muscle tissue. In this context, light-emitting diode therapy (LEDT) has been used to improve muscle performance in experimental models and human researches. Thereby, the investigators examined modulations in gene expression of muscle tissue as well as biochemical, biomechanic and histologic adaptations influenced by exercise associated to LEDT.

Full description

This study assessed muscle performance in isokinetic dynamometry and led press device, gene expression by RT-PCR, lactate, creatine kinase and morphology of muscle tissue by immunohistochemical analysis
