- During March and April 2004, the Copenhagen Muscle Research Center accomplished a research expedition in the Northwest of Greenland. The overall aim of the project is to elucidate the connection between genes, environment and early appearance of chronic diseases, particularly diabetes 2. Another intention is to throw light on metabolic adaptations in relation to health effects. Part of the project was the evaluation of mitochondrial respiratory parameters measured by high-resolution respirometry in permeabilized muscle fibers. These were prepared from small biopsies of the arm and leg of traditional life-style Inuit hunters, Western life-style Inuits, and a group of 16 Danish participants of the 42-days expedition.

Overview
Subject 10
Arrival of the Danish participants at Thule Air Base (Pituffik). Søren (left) is happy to be in Greenland, as he explains to Cindy Wright (centre). We have just returned from a trip with the helicopter to welcome the Inuit hunters arriving in the North Star Bay (Thule) after a 5-days dog sledge trip from Qaanaaq (Thule).
Skiing on the iscecovered Wolstenholme Fjord, Søren shows his acquired skills and endurance, close to the camp where they will put up their tents next to an iceberg. In the far background, an Inuit hunter with his sledge keeps guard - in case of the appearance of an icebear, his hunting gear is ready.
