Involvement of Autonomic Nervous System in Young Obese Males and Females
Journal Title: International Journal of Physiology - Year 2017, Vol 5, Issue 1
Abstract
Background: In obesity excessive adipose tissue accumulates and alters the metabolic profile with a variety of adaptations in cardiovascular functions. Method : 60 obese and 60 non obese healthy young adults aged 18-25 years were selected based on body mass index. Heart rate variability power spectral analysis and hand grip dynamometer tests were done to assess the sympathetic cardiovascular function. Results: HRV analysis found significantly lower values of TP, HF and significantly higher values of LF and LF/HF ratio among the obese group. Blood pressure response to an isometric exercise was reduced in obese group. Conclusion: Our data indicate that obese subjects have decreased parasympathetic activity seen as decrease in HF and increased sympathetic activity seen as increasing in LF and resting BP. BP response to isometric exercise was impaired in obese subjects due to lower sympathetic activation.
