RT Journal Article SR Electronic T1 Physiology studies at high altitude; why and how JF Journal of the Royal Army Medical Corps JO J R Army Med Corps FD British Medical Journal Publishing Group SP 131 OP 134 DO 10.1136/jramc-2013-000206 VO 160 IS 2 A1 Mellor, Adrian A1 Woods, D YR 2014 UL http://militaryhealth.bmj.com/content/160/2/131.abstract AB The military has always had an important role in high altitude research. This is due to the fact that mountainous regions often span borders and provide a safe haven to enemies. Deploying troops rapidly into high altitude environments presents major problems in terms of the development of high altitude illness. This paper examines the rationale for carrying out research at high altitude and the opportunities within the UK Defence Medical Services for carrying out this research.
