Objective: To ascertain the relationship of age, body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (PAD) and heart rate at rest with vagal cardiac index (VCI) verified through 4 Seconds Exercise Test (T4s). Methodology: Attended in this study 47 males divided between two groups: Sympathotonic (n = 17; 35.12 ± 14.5 years; 178 ± 6.86 cm; 81.47 ± 12.93 kg and 1.11 ± 0.04 to VCI ) and Normal ( n = 30; 24.37 ± 7.45 years; 177.5 ± 7.38 cm; 78.36 ± 10.70 kg and 1.39 ± 0.15, VCI ). The vagal cardiac index (VCI) was determined by digital electrocardiogram during the 4 Seconds Exercise Test. The blood pressure and heart rate were measured after 5 minutes of rest in dorsal decubitus through sphygmomanometer of mercury column and Polar S810 heart rate monitor respectively. Result: When the associated values of BMI, blood pressure at rest and heart rate at rest and chronological age between the two groups (Normal and Sympathotonic), the Sympathotonics showed values of age and BMI significantly higher compared with Normal subjects. In another variables there were not different between groups. Conclusion: we found that Sympathotonic individuals (VCI <1.20) had higher chronological age and BMI compared with Normal individuals (VCI > 1.20).
