MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Autonomic modulation and cardiorespiratory variables are influenced by numerous factors. Abdominal fat tissue is a relevant variables related to metabolic and cardiovascular disorders, including diabetes mellitus, dyslipidemia and hypertension, which are associated to increased risk of morbidity and mortality.
We evaluated cardiorespiratory variables and autonomic nervous system before and during recovery from exercise in healthy physically active men divided according to with waist-stature ratio (WSR): G1 – between 0.40 and 0.449 (N = 19), and G2 – between 0.45 and 0.49. This metholodigcal procedure is able to provide important information regarding the risk for developing cardiovascular disease in the future.
Our main findings indicated that healthy physically active men with waist-stature ratio values close to the risk limit (between 0.449 and 0.5) presented slower return of autonomic and cardiorespiratory variables to baseline values after moderate exercise. It suggests that this group present an elevated probability of developing cardiovascular disease in the future compared to the groups with lower values of waist-stature ratio.
MedicalResearch.com: What should readers take away from your report?
Response: Readers need to take care of their health even if they are considered healhty and physically active, they should go to the doctor every year in order to verify their health status, mainly if there is a family history of cardiovascular and metabolic disorder.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: Our group evaluates risk factors involved with cardiovascular diseases, the leading cause of all mortality in the world. In this sense, we recommend laboratories to endeavor to detect variables that may be related to cardiovascular and metabolic disorders development in healthy people.
Disclosures: The study was conducted at Paulista State University, UNESP, Marilia, SP, Brazil with collaboration of Oxford Brookes University, London, UK and received financial support from the São Paulo Research Foundation, FAPESP, São Paulo, SP, Brazil.
