Cerebral and Peripheral Electrical Stimulation on Isometric Quadriceps Strength

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation (NIBS) technique that has been investigated for the management of various health conditions. However, its ergogenic effect still has controversial results.

Peripheral electrical stimulation (PES) activates a complex neural network involving a series of neurotransmitters and receptors capable of promoting segmental and extrasegmental analgesia. Moreover, recent evidence has shown that PES can activate brain motor areas such as primary motor cortex.
