• 1 other identifier: AN-003
• Study Type: interventional
• Target: 100
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study was to analyze microcurrent short term effects used with aerobic exercise on abdominal fat.

Conditions

Obesity, Abdominal

Keywords

Abdominal fat; Metabolic syndrome; Microcurrent; Aerobic exercise; Lipolysis

Outcome Measures

Primary Outcomes (3)

• Change in catecholamines and glycerol concentrations

  Blood analysis collection was carried out with help from an clinical analysis technician. The volunteers were not fasting.

  10 minutes before the interventions, after interventions (duration of interventions - 90 minutes) and after 24 hours

• Change in proportion of energy source

  K4b2 (COSMED ®) was used for analysis of cardiopulmonary gas exchange in real time.

  Immediately before (for 3 minutes) and during exercise (duration of exercise - 50 minutes)

• Change in electromyographic activity

  Recording the surface electrical activity produced by rectus abdominis and external oblique in front bridge and side bridge exercise, respectively.

  5 minutes before and after microcurrent

Secondary Outcomes (4)

• Subcutaneous abdominal fat and visceral abdominal fat

  20 minutes before the interventions

• Suprailiac, vertical and horizontal abdominal skinfolds

  20 minutes before the interventions

• Perimeters measurements

  20 minutes before the interventions

• Change in cholesterol, triglycerides and glucose concentrations

  10 minutes before the interventions, after interventions (duration of interventions - 90 minutes)

Other Outcomes (3)

• International Physical Activity Questionnaire

  30 minutes before the interventions

• Food Frequency Questionnaire

  30 minutes before the interventions

• Bioimpedance values

  30 minutes before the interventions

Study Arms (2)

Transcutaneous microcurrent

EXPERIMENTAL

This group performed aerobic exercise just after microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, intensity below the sensitivity threshold and a maximum of 1 milliampere (mA). Every 20 minutes changed from 25 hertz (Hz) to 10 Hz

Device: Transcutaneous microcurrent; Device: Aerobic exercise

Control group

PLACEBO COMPARATOR

Control group performed aerobic exercise just after microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, but microcurrent device was switched off.

Device: Aerobic exercise

Interventions

Transcutaneous microcurrent DEVICE

Microcurrent in the abdominal region with four transcutaneous electrodes in a parallel position, intensity below the sensitivity threshold and a maximum of 1 mA. Every 15 minutes changed from 25 Hz to 10 Hz.

Transcutaneous microcurrent

Aerobic exercise DEVICE

50 minutes of aerobic moderate-intensity exercise (45-55% of maximal oxygen consumption (VO2 max)) using Karvonen´s formula, performed on a cycloergometer. Were used Borg scale (12-13), Polar® heart monitors to control heart rate and K4b2 to analyze the quantity of oxygen (O2) consumption and carbon dioxide (CO2) produced during exercise.

Control group; Transcutaneous microcurrent

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• age between 18 and 30 years.

You may not qualify if:

• submitted to other fat reduce procedure, to show cardiovascular risk factors or diseases and/or any physical condition limiting aerobic exercise. To present any contraindications to microcurrent and/or aerobic exercise, to take medication that influence lipid metabolism, and to be pregnant.
