- Acute effects of physical exercise with microcurrent in the adipose tissue of the abdominal region: A randomized controlled trialPublication . Noites, Andreia; Moreira, Anabela; Melo, Cristina; Faria, Miriam; Vilarinho, Rui; Freitas, Carla; Monteiro, Pedro; Carvalho, Paulo; Adubeiro, Nuno; Sousa, Maria; Santos, Rubim; Nogueira, LuisaIncreased abdominal fat and sedentary lifestyles contribute to cardiovascular disease risk. Low-intensity electrical current (microcurrent) on the abdominal region, associated with physical exercise, appears to be an innovative method to increase the lipolytic rate of abdominal adipocytes, in order to reduce abdominal fat. This study aimed to analyze the acute effects of microcurrent associated with an aerobic exercise program in healthy subjects in lipolysis. A double-blinded, randomized controlled trial was developed and conducted in a higher education school. Eighty-three healthy subjects, aged between 18 and 30 years old and with a 18.5 to 29.9 kg/m2 body mass index were randomly assigned either to an experimental or to a placebo group. Subjects received a trans-abdominal microcurrent stimulation for 40 min with (experimental group) or without (placebo group) electrical current, followed by a single aerobic exercise session (60 min at 45–55% VO2max intensity). Lipolytic activity (serum glycerol), abdominal fat (waist circumference, abdominal skinfold, ultrasonography), and serum lipid profile (serum triglyceride, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol) were evaluated in all subjects. Physical activity (International Physical Activity Questionnaire) and dietary intake (food-frequency questionnaire) questionnaires were applied. After the intervention, lipolytic rate was significantly higher (p = 0.003) in the experimental group (mean = 0.15) than in the placebo group (mean = 0.09). Glycerol results showed a statistically significant increase between baseline and after the intervention for both experimental group (p = 0.001) and the placebo group (p = 0.001). Combined use of microcurrent and physical aerobic exercise had an acute effect enhancing lipolytic rate comparing to exercise alone, in young healthy subjects.
- Effects of combining shockwaves or radiofrequency with Aerobic Exercise on subcutaneous adipose tissue and lipid mobilizationPublication . Marques, Leila; Neves, Joana; Pereira, Ana; Santiago, Ana; Troia, Sara; Vilarinho, Rui; Amorim, Maria Manuela; Noites, Andreia; Noites, Andreia; Vilarinho, RuiReducing abdominal subcutaneous fat is a common concern among women, with evidence suggesting that combining aerobic exercise with external shock waves or radiofrequency may enhance fat reduction. This study aimed to assess the effects of six sessions of external shock wave therapy or radiofrequency combined with an aerobic exercise program on abdominal subcutaneous fat and lipid mobilization, compared to the effects of an aerobic exercise program alone. Thirty-one women (aged 18–60) were randomly assigned to three groups: EG1 (shockwave therapy + aerobic exercise), EG2 (radiofrequency + aerobic exercise), and CG (aerobic exercise only). Body composition measures, mean temperature, adipose tissue thickness, lipid profile, and glycerol and interleukin-6 levels were assessed before and after intervention. A significant decrease in the EG groups compared to the CG was observed in the subcutaneous abdominal thickness (p < 0.001, effect size of η 2p = 0.446) and waist–hip ratio (p ≤ 0.001, effect size of η 2p = 0.408). No significant changes were verified in the levels of lipolytic activity, lipid profile, and interleukine-6. Six sessions of shockwave or radiofrequency therapy combined with aerobic exercise reduced subcutaneous fat thickness and improved hip–waist ratio more effectively than aerobic exercise alone, without affecting lipid mobilization by changes in lipid profile, lipolytic activity, or interleukin-6 levels.
