Abstract
Introduction: Cardiovascular diseases are a major public health problem and has contributed to high mortality rate in the adult population. One of the precursors factors of these diseases is low cardiac autonomic modulation. Thus, factors that may be related to increased cardiac autonomic modulation should be investigated in order to prevent cardiovascular diseases. One of these factors may contribute to increases in cardiac autonomic modulation is the practice of physical activity. However the studies that investigated this relationship has been controversial, often assessing physical activity by subjective methods, and there is no clarity to the different domains of physical activity are related differently with cardiac autonomic modulation. General Objective: To analyze the relationship of physical activity measured by direct measurement (accelerometer) with cardiac autonomic modulation in adults. Specific objectives: i) test the reproducibility of the Baecke habitual physical activity questionnaire confronted with physical activity data from the accelerometer; ii) Check through the Baecke questionnaire the different domains of physical activity (work, leisure and occupational activities) relate the same with the cardiac autonomic modulation; iii) analyze whether high levels of blood pressure and resting heart rate are related to low cardiac autonomic modulation regardless of nutritional status. Implications: The results of this study will support to clarify the relationship between physical activity and cardiac autonomic modulation considering a large sample of subjects (n = 214), as well as the different domains of physical activity are related to the autonomic modulation heart. These results may support to develop health promotion strategies.Key-words: Physical activity, heart rate variability; epidemiology, public health. (AU)
