Dynamic Electrostimulation on the Abdominal Muscles in Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
To determine the immediate effects on the abdominal musculature, assessed by ultrasound (RUSI), due to the application of electrostimulation using whole body electrostimulation together with physical exercise in healthy people and to compare with the application of local EMS in the abdominal area and the same physical exercise session. The same intervention is carried out for the control group as the WB-EMS group but simulated.

Detailed Description
-----------------
Evaluation of the immediate changes in the thickness of the abdominal muscles (Transversus abdominis, Internal and External Oblique and Rectus abdominis) and in the Interrectus distance after the physical exercise session together with whole body electrostimulation or local electrostimulation assessed by ultrasound (RUSI) in healthy people.
