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.
