Three Norwegian physicians crossed the inland glacier of Greenland on skis without any support. Body weight, fat and lean body mass was measured by dual X-ray absorptiometry scanning. Maximal oxygen uptake, lung capacity measurements, and various blood tests were recorded. Subjective health-related well-being and four transistory arousal states were also recorded (GHQ-30 and AD ACL, short form). One participant lost 1 kilo body weight, while the others gained 1 and 4 kilos, respectively, during the trip. Overall, lean body mass increased (1.2-4.0 kg), while body fat was reduced (0.4-2.7 kg). These changes reversed after four weeks. Bone mass, lung function and blood tests did not vary throughout the study period. The level of energy and calmness were high at baseline and even higher towards the end of the expedition, while the scores were low and stable for tiredness and tension. Subjective well-being increased for all participants towards the second half of the trip. We conclude that expeditions involving physical and mental strain can produce positive psychological changes. Catabolic conditions are avoidable. Changes in body mass composition revert quickly.
三名挪威医生在没有任何支持的情况下，滑雪穿越了格陵兰岛的内陆冰川。通过双能X线吸收法扫描测量体重、脂肪和瘦体重。记录最大摄氧量、肺容量测量值以及各种血液检测结果。还记录了与主观健康相关的幸福感和四种短暂唤醒状态（GHQ - 30和AD ACL简表）。在旅行期间，一名参与者体重减轻了1公斤，而其他参与者分别增加了1公斤和4公斤。总体而言，瘦体重增加了（1.2 - 4.0千克），而体脂减少了（0.4 - 2.7千克）。四周后这些变化逆转。在整个研究期间，骨量、肺功能和血液检测结果没有变化。在基线时能量和平静程度较高，在探险结束时更高，而疲劳和紧张程度的得分较低且稳定。在旅行后半段，所有参与者的主观幸福感都有所增加。我们得出结论，涉及身心压力的探险活动可以产生积极的心理变化。分解代谢状况是可以避免的。体重组成的变化恢复很快。
