Abstract
The influence of the spring sub-Arctic environment on selected physiological aspects related to human effectiveness was investigated within the First Battalion Royal Canadian Regiment during the Battalion's participation in Exercise Northern Ramble. To determine the minimum caloric requirements for various operational situations, energy expenditure assessment based upon the functional relationship between heart rate and work load was undertaken. Professional troops were observed to tolerate work loads at significantly lower heart rates than were militia personnel. The state of hydration of troops living on hard rations for the duration of the exercise was assessed. The effect of supplementary sodium chloride intake on the state of hydration was also examined. Absence of obvious symptoms of dehydration reflect the mild environmental conditions, lack of sustained strenuous physical activity and the ready availability of potable water. TRUNCATED
