Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Nevertheless aerobic exercise practice reduce globally lipidic sources and not locally . Electrolipolysis using microcurrent has been used in clinical practice as a technique to reduce abdominal fat. This technique can be applied transcutaneously or percutaneously seeming that the former is not so effective as skin can be an obstacle to the current effect on visceral and subcutaneous fat .
Abdominal fat excess is associated with cardiometabolic diseases and can be prevented using microcurrent and aerobic exercise to stimulate lipolysis.

Exercise after, Transcutaneos, 25-10Hz
Experimental group 1 performed aerobic exercise just after microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, intensity below the sensivity threshold and a maximum of 1 mA. Every 15 minutes changed from 25Hz to 10 Hz.
