Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

Comparisons Of Muscle Strength, Size, And Neuromuscular Function In Pre- And Post-Pubescent Males And Females, Zachary M. Gillen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of this study was to compare measurements of muscle strength, size, and neuromuscular function of the forearm flexors in pre- and post-pubescent males and females. Forty pre-pubescent (mean ± 95% confidence interval, age = 9.79 ± 0.35 yrs, n = 10 males, n = 10 females) and post-pubescent (age = 17.23 ± 0.58 yrs, n = 10 males, n = 10 females) participants completed this study. Biceps brachii muscle cross-sectional area (CSA) and muscle volume (MV) were quantified from ultrasound images. Participants completed maximal voluntary isometric contractions (MVICs) of the forearm flexors and extensors, and submaximal isometric step …

Encoding Of Saltatory Tactile Velocity In The Adult Orofacial Somatosensory System, Rebecca Custead

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Processing dynamic tactile inputs is a key function of somatosensory systems. Spatial velocity encoding mechanisms by the nervous system are important for skilled movement production and may play a role in recovery of motor function following neurological insult. Little is known about tactile velocity encoding in trigeminal networks associated with mechanosensory inputs to the face, or the consequences of movement.

High resolution functional magnetic resonance imaging (fMRI) was used to investigate the neural substrates of velocity encoding in the human orofacial somatosensory system during unilateral saltatory pneumotactile inputs to perioral hairy skin in 20 healthy adults. A custom multichannel, scalable …

Assessing The Effectiveness Of Nutrition And Physical Activity Self-Assessment For Child Care (Nap Sacc) For Changes In Physical Activity Behavior, Policy, And Environment In Nebraska Family Child Care Homes, Katie K. Bolte

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Nebraska is the first state to utilize NAP SACC and to modify the evidence-based program for family child care homes (FCCHs). The purpose of this study was to conduct a secondary data analysis to assess the effectiveness of a modified version of the NAP SACC approach in achieving changes in physical activity behavior, policy, and environment in Nebraska FCCHs caring for children ages 2-5 years. Results from this study will be used to improve the NAP SACC physical activity components for FCCHs and will help to inform trainers and the Nebraska Department of Health and Human Services, Nutrition and Activity …
