Comparing Body Composition Measures In Us Army Soldiers, Kishani Kirubaharan-Smith, James R. Bagley, Kent A. Lorenz, Maria J. Veri
International Journal of Exercise Science: Conference Proceedings
The United States (US) Army currently uses circumference measurements (with body mass index, BMI) to estimate body fat (BF) composition in soldiers. While this current system is easy to administer, it has been shown to have poor validity compared to other modern body composition assessment techniques, such as air displacement plethysmography (BodPod). Specifically, circumference/BMI measures do not account for different body types, especially among female soldiers. PURPOSE: This study aimed to compare 1) body composition measures in US Army Soldiers (BF% via circumferences vs BodPod) and 2) differences in BF% between males and females. We hypothesized there would be significant …

Anti-Cachexia Effect Of Polymorphonuclear Myeloid-Derived Suppressor Cell Depletion Therapy Is Not Present In Tumor-Bearing Mice Lacking T And B Cells, Hailey K. Gorman, Jonathan Specht, Michael Deyhle
International Journal of Exercise Science: Conference Proceedings
Polymorphonuclear (PMN) Myeloid-derived suppressor cells (MDSCs), are associated with poor cancer prognosis, partly due to their immunosuppressive effects on anti-cancer immunity. Cancer cachexia, characterized by debilitating skeletal muscle wasting, further reduces patient survival. Previously, antibody-mediated (anti-Ly6G) depletion of PMN-MDSCs attenuated skeletal muscle loss in mouse model of cancer cachexia. The mechanism by which PMN-MDSCs contribute to cachexia is unclear. Given the role that PMN-MDSCs play in supporting cancer disease progression depends on inhibiting anti-cancer adaptive immunity, we tested if the beneficial effects of PMN-MDSCs depletion on cachexia depend on the presence of adaptive immune cells. PURPOSE: We hypothesize that the …

International Journal of Exercise Science: Conference Proceedings
Tarnopolsky et al. (1990) showed significantly higher fat oxidation (FOx) in women versus men during endurance exercise, likely due to their higher concentrations of estrogen and type I muscle fibers. Prior studies support this stance (Venables et al. 2000), yet Wallis et al. (2006) showed no effect of sex on the metabolic response to exercise. PURPOSE: To compare substrate metabolism between men and women during submaximal exercise prescribed using metabolic (percent ventilatory threshold, %VT) and relative (percent maximal heart rate, %HRmax) intensities. METHODS: Healthy, non-obese men (n = 23) and women (n = 13) (age, % fat, and VO2 …
