O efeito do exercício físico por meio de intervenção presencial e on-line na composição corporal, parâmetros antropométricos e nos marcadores inflamatórios em mulheres previamente sedentárias

Abstract

The growing number of people suffering from overweight and obesity increases the demand for the development of intervention models for lifestyle adjustments based on the regulation of energy balance and adipose tissue metabolism. The study aimed to verify the influence of inperson and on-line intervention model on adipose tissue metabolic markers in obese women; 40 obese adult volunteers aged between 20 and 45 years will be selected, who will undergo 12 weeks of in-person and on-line multidisciplinary therapy with physical assessment, and collection of biological material for biochemical analysis, along with on-line support through emails, WhatsApp®, social media, and obesity-themed videos on an on-line platform (www.#12weeksfor, eat, fit, live). At the beginning and the end of the study, the volunteers performed a physical assessment of body composition, biochemical analyzes (glucose, adiponectin, leptin, and PAI-l). Volunteers could ask questions daily via email or WhatsApp® and received information about diet and exercise. The results were analyzed using SPSS software – version 22.0, for OS. Data normality was obtained using the Kolmogorov Smirnov test and expressed as mean and standard deviation (SD). To compare the means found between groups and intragroup, ANOVA Two Way and Fisher's post-hoc were applied, adopting the value of “p”, and thus verifying the significance found between the values. The dependence behavior of the variables was verified by simple linear regression. Based on the findings, it was possible to conclude that 12 weeks of in-person and on-line therapy can be widely used to combat obesity in this population, which reinforces that, even in a short space of time, significant changes can occur in all components of the body composition, as well as in the leptin, adiponectin and PAI-1 fractions. However, more studies need to be carried out to confirm in the long term and through a cut-off study that can cover a larger number of participants, thus fully elucidating and understanding the exact mechanisms that are involved in the weight loss process, changes in body composition, changes in leptin, adiponectin and PAI-1 fractions.
