Actual (reported)Interferential electrical stimulation (IES) increases local blood flow. It is not known whether increases in blood flow may be caused by inhibition of sympathetic activity, mediated by muscle metaboreflex activity. The purpose of this study was to evaluate the effect of IES on metaboreflex activation in healthy subjects.

Actual (reported)Muscle Metaboreflex Reflex
Calf blood flow
Participants will be followed for the duration of metaboreflex activity (up to 30 minutes)
The individuals are treated acutely with interferential electrical stimulation (IES) during 30 min, providing a continuous flow of symmetrical rectangular interferential current biphasic pulses using bipolar electrodes with two channels and a slope of 1/5/1. The fixed current is adjusted to 4000 Hz, with the current AMF at 100 Hz and an AMF variation of 25 Hz (25% of AMF).
The same instructions and electrode positions were provided to the placebo, although the equipment did not provide any stimulation current
