Two groups (10 each) of healthy men in the age group of 2344 years participated in the study. Group A consisted of fresh inductees to Antarctica for conducting scientific research during austral summer. Group B consisted of winter team members who had already completed 14 months of stay at Antarctica. The HRV experiments were conducted at New Delhi; and on 7th, 30th and 60th day of stay at Antarctica. The HRV was measured as spectral components of low frequency (LF) 0.04-0.05 Hz, related to sympathetic activity and high frequency (HF) 0.15-0.50 Hz due to vagal efferent activity and the sympathovagal balance as LEVHF ratio. The present study was conducted to evaluate the role of sympathetic and parasympathetic components of ANS in HR regulatory mechanisms in clinically healthy subjects, during their short as well as long term sojourn at Antarctica.
