A double blind, repeated-measures design was utilized with 10 healthy, college-age males. Participants were placed in the placebo (olive leaf oil) or experimental (O3FA) group, consuming 3,000 …

State Population Influences Athletic Performance Combine Test Scores In High School-Aged American Football Players, Zachary M. Gillen, Marni E. Shoemaker, Brianna D. Mckay, Joel T. Cramer

Department of Nutrition and Health Sciences: Faculty Publications

This study compared athletic performance differences among high school American football combine participants originating from states of different population sizes. High school-aged American football players (n=7,214) who had participated in athletic performance combines between March 2015 and January 2016 were included in this analysis. Data included combine date and location, school state of origin, football position, class, height, weight, 10-, 20-, and 40-yd dash times, pro-agility, L-cone drill, vertical jump, broad jump, and power push-up. Participants were separated into high- (state population>10,000,000; HIGH; n=2,804), mid- (state population=5,000,000-9,999,999; MID; n=2,911), or low-population (state population<5,000,000; LOW; n=1,499) state of origin. Data were allometrically scaled to account for differences in body mass across high school grade levels and American football positions. All statistical analyses were performed on the allometrically scaled data. LOW athletes performed better than HIGH athletes in the 20-yd dash (p≤0.01). LOW athletes performed better than HIGH and MID in the 40-yd dash, proagility, broad jump, and power push-up (p<0.01). LOW and HIGH athletes performed better than MID in the Lcone and vertical jump (p<0.01). When considering population size, athletes originating from LOW states may demonstrate higher levels of athletic performance in football combine events hypothetically due to more opportunities for sports participation and playing time, leading to greater athletic development. Youth and high school coaches in MID and HIGH states might consider providing more opportunities for playing and individualized coaching to encourage long-term athletic development.

The effects of UroA on hepatic triglyceride accumulation, adipocyte size, mitochondrial DNA content, and proinflammatory gene expressions were determined. The impact of UroA on …

Milk-Derived Exosomes And Metabolic Regulation, Janos Zempleni, Sonal Sukreet, Fang Zhou, Di Wu, Ezra Mutai

Department of Nutrition and Health Sciences: Faculty Publications

Exosomes are natural nanoparticles that play an important role in cell-to-cell communication. Communication is achieved through the transfer of cargos, such as microRNAs, from donor to recipient cells and binding of exosomes to cell surface receptors. Exosomes and their cargos are also obtained from dietary sources, such as milk. Exosome and cell glycoproteins are crucial for intestinal uptake. A large fraction of milk exosomes accumulates in the brain, whereas the tissue distribution of microRNA cargos varies among distinct species of microRNA. The fraction of milk exosomes that escapes absorption elicits changes in microbial communities in the gut. Dietary depletion of …

Comparison Of Calculated Energy Expenditure To Measured Energy Expenditure In Overweight And Obese Burn Patients In An Icu Setting: A Retrospective Study, Elle Maree Skinner, Deborah A. Cohen, Orrin B. Myers, Diana Gonzales-Pacheco

Individual, Family, and Community Education ETDs

Burns cause massive dermal wounds. Wound healing elicits a significant catabolic response and increase in energy expenditure, and thus, calorie needs. Overfeeding and/or underfeeding the overweight and obese critically ill patient can increase complications. Indirect Calorimetry (IC) is considered the ‘gold standard” for the measurement of Energy Expenditure (EE). Predictive equations are calculated to estimate EE instead. This study is a retrospective chart review. The difference between predictive energy expenditure (via Curreri formula) and measured IC were analyzed via non-parametric Wilcoxon signed rank match paired tests. Curreri equation prediction was analyzed on the ability to match IC (0% over or …
