Recent advances in enCORE® software for the GE iDXA include the ability to estimate VAT. Low Energy Availability has been suggested to disrupt numerous hormonal functions in endurance athletes. Endurance runners have the propensity to under-consume calories for the amount of training performed. This may lead to increased physiological stress leading to a negative impact on hormonal status. Limited studies have been performed in male endurance runners to define VAT. Objective: The purpose of this study was to examine VAT levels in male runners, and identify correlations between VAT, hormonal, and dietary factors.Methods: The cross-sectional study analyzed data from 41 male endurance runners between 20-50 years old who ran at least 40 miles per week. Participants were fitted for GT3X+ Actigraph accelerometer, instructed how to complete a 3-day food and activity record, had an iDXA performed, and blood samples taken. Blood was taken on a minimum of 9 hour fast, and hydration status was documented using a refractometer. Food records were processed using ESHA Food processing software. VAT was assessed using the iDXA enCORE® software.Results: VAT mass in this group was 0.7578 +/- 0.5185 pounds. Significant Pearson correlations were identified between cortisol and a few dietary factors. Regression modeling to predict VAT identified overall body fatness, fat free mass and LDL as the most robust model. Conclusions: This cohort of male endurance runners demonstrated a low VAT limiting generalizability of the results. Very little is understood about the impact of endurance activity on VAT and more research is needed to confirm these results. 2019-08-27 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1555574688906344 http://rave.ohiolink.edu/etdc/view?acc_num=osu1555574688906344 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
