The physiological and metabolic effects of extended expeditions to polar and high altitude environments are an area of rapidly expanding research interest.
Challenging physical activity in extreme cold or altitude is with associated weight loss, physical deterioration and occasionally death, and as a result researchers are looking more closely at the metabolic cost and nutritional preparedness for such activities.
The Global Polar and Altitude Research Registry will prospectively study individuals before and after extended journeys to these environments. Research will take place in the NIHR Clinical Research Facility (CRF) Human Metabolic Unit (HMRU) in the University Hospitals Coventry and Warwickshire NHS Trust, Coventry.
Full physiological measurements will be taken pre- and post-expedition, and metabolic profiling using whole-body calorimetry in the metabolic chamber of the HMRU where strict environmental conditions can be maintained. With time, a body of data will be collected to better understand similarities and differences between individuals and expeditions, and to understand and address the underlying metabolic mechanisms, so improving performance and safety.
With a better understanding of metabolic cost of polar and high altitude travel, we can begin to understand the total calorific intake required for physical activity and adequate thermoregulation during such expeditions.
