Abstract : The purpose of this project has been to determine the relationship between menstrual function, gender and total energy expenditure (TEE) on measures of bone health in males and females exposed to seasonal arduous work (extended operations). A secondary purpose of this project has been to determine the effect of gender and the menstrual cycle on substrate utilization (glucose metabolism) during exercise. Because the critical issues cannot be represented by a single investigation, this project involves a series of investigations that will be used to better determine some of the underlying health issues surrounding females in arduous work environments. The series of investigations that are being currently conducted will be referred to in the order in which they have been initiated. This includes: I - Effects of gender and the menstrual cycle on substrate utilization during exercise and II - Effects of menstrual function, gender, total energy expenditure (TEE), and the maintenance of energy balance on measures of bone health in males and females. At this time, data analyses and collection are still ongoing for Investigations I and II, respectively. Preliminary data findings are presented in the text for both components.
