Stroud, Mike

A similar suggestion is made for maintenance of the mental activities of Mike Stroud and Ranulph Fiennes during their long trans-Antarctic expedition when, at times, their blood glucose fell to about 1 mmol/L (Chapter 13). Unfortunately the blood level of ketone bodies was not measured during this trek. 

The heat production from strenuous muscle activity can maintain normal body temperature even in the harshest of environmental conditions Mike Stroud and Ranulph Fiennes, during their Transantarctic expedition, even without excessive amounts of clothing, generated sufficient heat from the muscular effort involved in walking and pulling their sledges, that normal body temperature was maintained (Stroud, 1997). 

Quantitative studies of energy metabolism and fuel utilisation in very prolonged physical activity were performed by Mike Stroud during his Antarctic expedition with Ranulph Fiennes in 1992. One part of the study was measurement of energy expenditure by the dual isotope techniques (Chapter 2). Calculated over the whole expedition, the average daily energy expenditure of Stroud and Fiennes was 29 MJ but on particularly arduous days it increased to... 

It might be considered that running an ultramarathon (various distances from 50 to >100 miles), completing a 24-hour race, racing in the Tour de France or climbing Mount Everest are the ultimate in endurance activities. However, these activities may seem physically insignificant when compared with transantarctic expeditions, such as that carried out by R. Fiennes and M. Stroud in 1992-93. Not only was it a remarkable endurance feat but they carried out smdies on energy expenditure, body composition and nutrition. To illustrate this feat, we can do no better than quote from Mike Stroud s paper.
