Physiological parameters and activity were recorded monthly on 19 men wintering at a polar base. A comparison was made between those in their first Antarctic winter (Group A, n = 13) and those in their second consecutive Antarctic winter (Group B, n = 6). Group A were more active (p less than 0.001) and spent more time outside (p less than 0.001) during the summer months than during the darker and colder winter period. Combined data showed no correlation between total activity and meteorological conditions, but a clear (p less than 0.001) negative correlation with time spent outside and wind speed. In the first part of the year group A became fitter (as shown by a lower heart rate at a VO2 1.51 min-1), increased basal oxygen uptake under standard conditions and put on body and fat mass. These changes were not demonstrated in group B living and working under identical conditions. Lean body mass of both groups rose throughout the year (A, p less than 0.001; B, p less than 0.05). These data suggested that the changes in physiological parameters in group A were in response to the life style and activity of a polar base, rather than to the Antarctic climate per se.
对在极地基地过冬的19名男性每月记录其生理参数和活动情况。对首次在南极过冬的人员(A组,n = 13)和连续第二个南极过冬的人员(B组,n = 6)进行了比较。A组在夏季比在更黑暗寒冷的冬季更活跃(p < 0.001),在户外的时间也更多(p < 0.001)。综合数据显示,总活动量与气象条件之间无相关性,但与在户外的时间和风速呈明显的负相关(p < 0.001)。在一年的上半年,A组身体状况更佳(表现为在每分钟摄氧量1.5升时心率更低),标准条件下基础氧摄取量增加,体重和脂肪量增加。在相同条件下生活和工作的B组未出现这些变化。两组的去脂体重全年均增加(A组,p < 0.001;B组,p < 0.05)。这些数据表明,A组生理参数的变化是对极地基地生活方式和活动的反应,而非对南极气候本身的反应。
