- Effect of an aerobic exercise session combined with abdominal radiofrequency on lipolytic activity in women: Randomized control trialPublication . Noites, Andreia; Vale, Ana Luísa; Pereira, Ana Sofia; Morais, Andreia; Vilarinho, Rui; Carvalho, Paulo; Amorim, Manuela; Moreira, Teresa; Mendonça, AdrianaAbdominal adiposity is a cardiovascular risk factor; it is assumed that the combination of radiofrequency and physical exercise may decrease this excess of adipose tissue. To understand whether an aerobic physical exercise session associated with abdominal radiofrequency increases the level of lipolytic activity. The study analyzes the effect of a combined aerobic exercise session with radiofrequency. Participants were 30 healthy female volunteers, aged 18-28 years, randomly assigned to an experimental group and placebo group. They were characterized by a sociodemographic questionnaire, the International Physical Activity Questionnaire and the Food Frequency Questionnaire. The groups performed an abdominal radiofrequency session followed by moderate aerobic exercise, assessing glycerol concentration and lipid profile values before and after the intervention. In the experimental group, a percentage of potency was used that allowed to maintain the temperature between 40º C and 42º C to the epidermis. In the placebo group, the power of the radiofrequency was 0 Watt. To compare results, Student's t test was used for a significance level of 0.05. There were no significant changes in glycerol concentrations between groups (P > 0.05). There were no changes in the lipid profile of both groups after the intervention (P > 0.05). The association of exercise with radiofrequency did not present an increased effect on lipolytic activity when compared to the isolated exercise. The application of this technique is a safe intervention.
- Effect of four sessions of aerobic exercise with abdominal radiofrequency in adipose tissue in healthy women: Randomized control trialPublication . Vale, Ana Luísa; Pereira, Ana Sofia; Morais, Andreia; Carvalho, Paulo; Vilarinho, Rui; Mendonça, Adriana; Noites, AndreiaAbdominal adiposity is a cardiovascular risk factor; it is assumed that the combination of radiofrequency and physical exercise may decrease this excess of adipose tissue. To analyze the effect of four intervention sessions on abdominal adipose tissue. The study analyzes the effect of four sessions of aerobic exercise combined with radiofrequency. Participants were 28 healthy female volunteers, aged 18-28 years, randomly assigned to an experimental group and a placebo group. They were characterized by a sociodemographic questionnaire, the International Physical Activity Questionnaire and the Food Frequency Questionnaire. The groups performed four sessions of abdominal radiofrequency followed by moderate aerobic exercise, assessing body mass, body mass index, fat mass, waist circumference, waist/height ratio, subcutaneous adipose thickness, and horizontal abdominal adipose fold at the first and fourth sessions. In the experimental group, a percentage of potency was used that allowed to maintain the temperature between 40°C and 42°C to the epidermis. In the placebo group, the power of the radiofrequency was 0 W. To compare results, Student's t test was used for a significance level of 0.05. There was a statistically significant decrease in waist circumference, abdominal subcutaneous adipose thickness, and horizontal abdominal fold in the experimental group compared to the placebo group (P < 0.05).
- Effects of radiofrequency on adipose tissue: A systematic review with meta-analysisPublication . Vale, Ana Luísa; Pereira, Ana Sofia; Morais, Andreia; Noites, Andreia; Mendonça, Adriana Clemente; Martins Pinto, Juliana; Vilarinho, Rui; Carvalho, PauloEquipment that acts in the reduction in adipose tissue are becomingwidely investigated. One of the resources that begin to gain recognition is radiofre-quency. To verify the existence of scientific evidence and the methodological qualityof the articles on the effects of radiofrequency in the reduction in adipose tissue. Systematic review with meta‐analysis on the effects of radiofre-quency on adipose tissue. The research was carried out using several databases andincluding experimental studies only in humans. The evaluation of the methodologicalquality of the articles was done based on the PEDro Scale. Twelve articles related with adipose tissue and cellulitis were included.There was a great variability of protocols, and the methodological quality was gen-erally low and the methods most used for the evaluation of results were anthro-pometry, photography, and histopathology. Clinical results suggest a positive effectof radiofrequency on the reduction in adipose tissue, proving an increase in adipo-cyte lipolysis. After statistical analysis, it was verified that the anthropometry pre-sented questionable results. The clinical results of the studies point to the positive effects ofradiofrequency on the reduction in adipose tissue; however, the low methodologicalmake this topic still debatable, requiring more controlled studies.
