Brief Description (Abstract):

The Antarctic environment presents extremes of meteorological elements to the members of expedition, A study was conducted to analyze the mechanisms of decreased performance of subjects in Antarctica, for which the first author participated in the Tenth Indian Scientific Expedition. Harvard step test was performed on seventeen members and their heart rate, blood pressure, oral temperature and skin temperature. Two recordings were taken viz. basal (in the ship) and the other after 8 weeks of the Antarctic stay. A cold chamber simulation study, back at India, was conducted on rats to study the effect of cold exposure alone as the primary factor affecting the physical performance. A significant reduction in Physical Fitness Index was observed in men after Antarctic stay. Whereas, in rats there was an improvement after cold acclimatization. The Hypodynamia was more marked than anticipated in men and cold exposure alone cannot be the sole contributing factor.

Status: Completed

Purpose: Life at a polar station involves a continued and high level of physical activity. All station personnel help with domestic chores which often involve quite heavy manual labour, digging snow, carrying loads around the station, apart from attending to their assigned jobs at the station. The energy cost of performing any task in polar region is quite high because of the difficulties in working in heavy clothing and travelling in the harshest known environmental conditions which limit the physical efficiency of the worker. Although extensive studies have been conducted to evaluate the changes in body functions induced by various forms of stresses in Antarctica, most of the researchers have devoted their effort to study the state of individual function system.
