Physical Activity Patterns and Related Health Outcomes of Omani Elementary Children in The Context of Attending School

Investigators:Marc Locbaum(PI), and Youngdeok Kim(Co-PI)


Funded by the Sultan Qaboos Cultural Center

The grant will be used to study the physical activity levels and related important health measures (e.g., sedentary behaviors, sleep quality, body composition, and perceived physical abilities) and environmental constraints (e.g., school policies) in Omani children during 2017 – 2018 academic years.

Incorporating wearable technology into Physical Activity Instructional Program:
A cluster randomized control trial in University Settings

Investigators:Youngdeok Kim, Angela Lumpkin, Marc Lochbaum, Karla Kitten


Funded through the Society of Health and Physical Educators (SHAPE) America

A primary aim of this project is to examine the feasibility and efficacy of incorporating modern wearable technology into the Physical Activity Instructional Program (PAIP) for promoting long-term, habitual physical activity among college students using a rigorous experimental design, a cluster randomized controlled trial in University setting.

Day-to-day reciprocal associations of sleep, physical activity, and sedentary behavior among adolescents: An Autoregressive cross-lagged modeling approach

Investigators: Youngdeok Kim, Masataka Umeda


Funded through a Paffenbarger-Blair Fund for Epidemiological Research on Physical Activity from the American College of Sports Medicine Foundation, 2015

The overarching goal of this project is to examine the reciprocal associations between sleep, physical activity (PA) and screen-based sedentary behavior (SB) in young adolescents, one of the most vulnerable populations for sleep problems. The project will be a short-term longitudinal design in nature measuring objective and subjective sleep health, objective level of PA, and time spent in screen-based SB (e.g., watching TV, playing a video game) across three consecutive school days. Advanced analytic techniques based on an autoregressive cross-lagged model will be applied to develop the model examining the reciprocal associations of study variables.

Exercise Physiology

The Effect of Egg Protein on Energy Intake, Physical Activity, and Energy Balance in Adults

Investigators: Emily Dhurandhar, David Allison (University of Alabama at Birmingham)


Funded by the Egg Nutrition Research Center

The objective of this project is to determine if egg protein has an impact on satiety, energy intake and energy expenditure through physical activity in a free-living, ad libitum setting. In this double-blind cross over study, participants will consume either a carbohydrate or egg protein shake every day for 5 days, and their satiety, food intake and exercise energy expenditure will be compared during the two treatment periods.

Impact of Reduced Arterial Stiffness on Peripheral Vascular Function and Mobility

Investigators: Joaquin U. Gonzales, Michael W. O'Boyle (TTU – Neuroscience)


Funded through the American Heart Association (Southwest Affiliate), Beginning Grant-in-Aid, 2015-2017

The objective for this project is to identify mechanisms by which central arterial stiffness may contribute to walking fatigue in older adults. We will accomplish this objective by using a dietary supplementation to study the effect of reducing central arterial stiffness on peripheral factors that may mediate the association between central arterial stiffness and walking fatigue.
