Dynamic Electrostimulation on the Abdominal Muscles in Healthy Individuals

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.

About this study

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.

Treatment and study plan

WB-EMS (Whole body electrostimulation)

Device

Application of physical exercise and electrical stimulation on the abdominal muscles through the WB-EMS during 20 minutes training session with specific exercise (CORE)

EMS

Device

Application of physical exercise and electrical stimulation on the abdominal muscles through the EMS during 20 minutes training session with specific exercise (CORE)

WB-EMS off

Device

Application of physical exercise without electrical stimulation on the abdominal muscles through the WB-EMS off during a 20 minutes training session with specific exercise (CORE).

Other names: Control group

Primary outcomes

  1. Measurement of muscle thickness of the abdominal muscles by ultrasound through the technique "Rehabilitative Ultrasound Imaging" (RUSI).

    Time frame: One day

    Measure muscle thickness before and after exercise with electrostimulation

  2. Measurement of the Distance between Rectus abdominis using ultrasound (RUSI)

    Time frame: One day

    Measure the distance between Rectus abdominis before and after exercise with electrostimulation

Secondary outcomes

  1. International physical activity questionnaire (IPAQ)

    Time frame: One day

    Classification according to low, moderate or high physical activity level

  2. Nijgemen questionnaire

    Time frame: One day

    A level of respiratory distress equal to or higher than 23 points is an exclusion criterion for exclusion from the study

  3. Body height

    Time frame: One day

    Body height in meters

  4. Body weight

    Time frame: One day

  5. Body mass index

    Time frame: One day

    Calculation of body mass index in Kg/m2 according to Queletet method

  6. Heart frequency

    Time frame: One day

    Measurement of the heart rate (beats per minute)

  7. Blood pressure

    Time frame: One day

    Measurement of systolic and diastolic blood pressure using a sphygmomanometer

  8. body temperature

    Time frame: one day

    Measurement of body temperature in Celsius with a digital thermometer
