- 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.
- Avaliação dos resultados da aplicação combinada do ultrassom e da drenagem linfática manual no fibro-edema gelóidePublication . Rodrigues, Elisa; Lopes, André; Adubeiro, Nuno; Faria, MiriamO fibro-edema gelóide (FEG), popularmente conhecido como celulite, é uma alteração comum da topografia da pele que reflete disfunções precoces nos sistemas vascular e/ou metabólico e conjuntivo, afetando milhões de pessoas no mundo, predominantemente mulheres. A partir de perspetivas em saúde cada vez mais holísticas e integrativas, poder-se-á usar o FEG como indicador precoce para doenças cardiovasculares e metabólicas. As terapias eficazes podem ser chaves no diagnóstico dos principais sistemas disfuncionantes envolvidos. Muitos métodos são utilizados no seu tratamento, entre os quais se incluem a drenagem linfática manual (DLM) e o ultrassom.
- Body mass index and visceral fat: correlation with serum lipid profile in healthy young adultsPublication . Moreira, Anabela; Noites, Andreia; Couto, Miriam; Vilarinho, Rui; Melo, Cristina; Sousa, Manuela; Monteiro, Pedro; Carvalho, Paulo; Adubeiro, Nuno; Nogueira, Luisa; Santos, RubimMetabolic and cardiovascular complications and obesity association is well described. Body mass index (BMI) is commonly used to assess obesity, but does not reflect body fat distribution. Abdominal obesity, namely visceral adipose tissue (VAT), is associated with greater risk for those metabolic impairments, including dyslipidemia, than adiposity in other regions of the body. Objective: To determine the correlation between serum lipid profile and anthropometric measures (BMI and VAT) in young healthy adults.
- Efeito da eletrolipólise no tecido adiposo abdominal: estudo pilotoPublication . Couto, Miriam; Noites, Andreia; Silva, Patrícia; Adubeiro, NunoO excesso de tecido adiposo abdominal associa-se a distúrbios cardiometabólicos. A microcorrente associada ao exercício físico aeróbio poderá auxiliar na estimulação da lipólise para diminuir a quantidade dessa gordura.
- Efeito e fatores preditivos da variação do glicerol sanguíneo induzido por eletrolipólise associada a exercício físico moderadoPublication . Couto, M; Noites, Andreia; Vilarinho, Rui; Melo, Cristina; Monteiro, Pedro; Moreira, A.; Cerqueira, Maria Manuela Amorim; Costa, D.; Adubeiro, Nuno; Nogueira, Luisa; Santos, RubimA acumulação de triglicerídeos no tecido adiposo abdominal acarreta risco acrescido para a saúde. Existem poucos estudos que demonstrem o efeito da eletrolipólise sobre o adipócito. A eletrolipólise poderá ser uma medida terapêutica coadjuvante ao exercício com o objectivo de potenciar a lipólise localizada. Assim torna-se pertinente reproduzir tais estudos, explorando se existem características individuais preditivas de mobilização lipolítica
- Effects of aerobic exercise associated with abdominal microcurrent: a preliminary studyPublication . Noites, Andreia; Nunes, Rita; Gouveia, Ana Isabel; Mota, Alexandra; Melo, Cristina; Vieira, Ágata; Adubeiro, Nuno; Bastos, José MesquitaTo analyze the short- and long-term effects of microcurrent used with aerobic exercise on abdominal fat (visceral and subcutaneous). Methods: Forty-two female students from a university population were randomly assigned into five group: intervention group (IG) 1 (n=9), IG2 (n=9), IG3 (n=7), IG4 (n=8), and placebo group (PG) (n=9). An intervention program of 10 sessions encompassing microcurrent and aerobic exercise (performed with a cycloergometer) was applied in all groups, with slightly differences between them. In IG1 and IG2, microcurrent with transcutaneous electrodes was applied, with different frequency values; 30-minute exercise on the cycloergometer was subsequently performed. IG3 used the same protocol as IG1 but with different electrodes (percutaneous), while in IG4 the microcurrent was applied simultaneously with the cycloergometer exercise. Finally, the PG used the IG1 protocol but with the microcurrent device switched off. All groups were evaluated through ultrasound and abdominal perimeter measurement for visceral and subcutaneous abdominal fat assessment; through calipers for skinfolds measurement; through bioimpedance to evaluate weight, fat mass percentage, and muscular mass; and through blood analyses to measure cholesterol, triglyceride, and glucose levels. After intervention sessions, visceral fat decreased significantly in IG1 compared with the PG. Subcutaneous fat was reduced significantly in all groups compared with the PG. After 4 weeks, almost all results were maintained. The addition of microcurrent to aerobic exercise may reduce fat more than does aerobic exercise alone.
- A influência da electrolipólise associada ao exercício físico na atividade metabólicaPublication . Noites, Andreia; Couto, Miriam Faria; Monteiro, Pedro; Vieira, Ágata; Adubeiro, Nuno; Carvalho, Paulo; Gouveia, Ana; Nunes, Ana; Mota, Alexandra; Leal, Carla; Rodrigues, Cláudia; Sousa, Gisela; Silva, PatríciaO excesso de gordura abdominal associa-se a patologias cardiometabólicas. A microcorrente poderá ser coadjuvante ao exercício aeróbio na estimulação da lipólise, prevenindo riscos de saúde. O exercício físico aeróbio constitui uma modalidade capaz de diminuir o tecido adiposo, por estimular a lipólise através da elevação do nível de catecolaminas, resultantes do aumento da actividade do sistema nervoso simpático. O tipo de exercício físico mais adequado para consumo predominante de lípidos é o exercício aeróbio prolongado e de intensidade moderada. No entanto, na prática de exercício físico as fontes lipídicas são globais o que sustenta a utilidade de procedimentos que promovam o gasto de gordura localizada na região abdominal. A electrolipólise, que pode ser realizada pela aplicação de microcorrente de baixa frequência, poderá ser usada com este intuito, uma vez que a activação do sistema nervoso simpático, juntamente com a alteração da polaridade da membrana celular dos adipócitos e o aumento do fluxo sanguíneo, parecem ser os responsáveis pela promoção da lipólise e aumento do metabolismo local. Para além destes mecanismos, a microcorrente favorece a degradação de triglicerídeos ao promover a activação das enzimas triglicerídeo lípase e lípase hormono-sensível. Após a hidrólise de triglicerídeos torna-se fulcral o exercício físico para que os ácidos gordos em circulação sejam utilizados como fonte de energia. Porém não existe evidência científica que comprove os efeitos da electrolipólise associada ao exercício físico bem como consenso nos parâmetros que devem ser utilizados para electrolipólise, neste sentido vários estudos tem sido realizados no âmbito da linha de investigação de sistema tegumentar e metabólico da ESTSP.
- Plaster body wrap: effects on abdominal fatPublication . Moreira, Juliana Santos; Melo, Ana Sofia; Noites, Andreia; Couto, Miriam F.; Melo, Cristina; Adubeiro, NunoAbdominal fat is associated with metabolic disorders, leading to cardiovascular risk factors and numerous diseases. This study aimed to analyze the effect of plaster body wrap in combination with aerobic exercise on abdominal fat. Methods: Nineteen female volunteers were randomly divided into intervention group (IG; n = 10) performing aerobic exercise with plaster body wrap, and control group (CG; n = 9) performing only exercise. Subcutaneous and visceral fat were measured using ultrasound; subcutaneous fat was also estimated on analysis of skinfolds and abdominal perimeters. At the end of the 10-sessions protocol, the IG demonstrated a significant decrease (p ≤ 0.05) in subcutaneous fat at the left anterior superior iliac spine (ASIS) level and in iliac crest perimeter measurements. A large intervention effect size strength (0.80) was found in subcutaneous fat below the navel and a moderate effect size strength on the vertical abdominal skinfold (0.62) and the perimeter of the most prominent abdominal point (0.57). Comparing the initial and final data of each group, the IG showed a significant decrease in numerous variables including visceral and subcutaneous fat above and below the navel measured by ultrasound (p ≤ 0.05). Plaster body wrap in combination with aerobic exercise seems to be effective for abdominal fat reduction.
