| Summary: | Background and Objectives: Increased sympathetic activity,
decreased parasympathetic activity and sympathovagal
imbalance (SVI) has been reported in obese individuals. However,
the SVI and its association with visceral fat in overweight health
care students have not been explored. Therefore, in the present
study, we have assessed heart rate variability (HRV) and its
association with visceral fat in overweight health care students.
Materials and Methods: Frequency domain parameters of HRV,
body fat distribution and baseline anthropometric parameters
were recorded in the control (n=40) and overweight (n=40)
individuals. Further, the association of visceral fat with HRV was
analysed.
Results: There was no significant difference in age and height
of overweight group and control group (p = 0.732). The baseline
heart rate and blood pressure (p<0.001) were higher in the
overweight group. Total body fat, subcutaneous fat and visceral
fat were higher in the overweight group (p<0.001). Among
frequency domain parameter of HRV, LFnu and LF: HF were more
in the overweight group (p<0.001). Further, HFnu was less in the
overweight group (p<0.001).
Conclusion: Sympathovagal imbalance due to increased
sympathetic activity and its association with visceral fat was
observed in overweight individuals. |
