Muscle and Liver Carbohydrates: Response to Military Task Performance by Women and Men
Abstract
During this second year we have made significant progress in two areas: (1) We have implemented the study and data analysis protocols. Currently we can acquire and analyze data in both the MRI and the MRS areas of the project. (2) We have completed the majority of studies in the MRI portion of the project, and we have completed a significant number of MRS studies. From the studies that we have completed we can draw some preliminary conclusions. (A) Women are capable of completing the task, although men finish about twice as often. (B) MRI is capable of detecting gender differences in our lift & carry task, and it directs us to the muscles that are best studied with MRS. (C) Liver glycogen is not significantly depleted by the exercise protocol in either gender. (D) Quadriceps muscle glycogen is minimally depleted in both genders suggesting that these large muscles are not heavily recruited by our exercise protocol, perhaps because the work is distributed among 25-35 different muscles. This is in agreement with our MRI data. Size may be a better indicator of the ability to complete this task than gender.
