Hispanic And Black Children’S Ability To Regulate Energy Intake Across Parent Feeding Styles, Leslie A. Frankel, Sheryl Hughes, Teresia O'Connor, Tzu-An Chen

International Journal of Exercise Science: Conference Proceedings

Purpose: Satiety Responsiveness (SR) is an individual’s sensitivity to feelings of fullness and hunger (Carnell and Wardle, 2007). Enjoyment of Food (EF) is how responsive a person is to food cues (Carnell and Wardle, 2008). Higher levels of SR and EF are related to BMI (Carnell and Wardle, 2008) and less eating in the absence of hunger (Wardle, Llewellyn, Sanderson and Plomin, 2009) in children. However, little is known about the relationship between these two appetitive traits and parent feeding style, especially amongst low income minority samples. Method: 160 Hispanic and 141 Black parents (62.58% underweight/healthy weight, 18.71% overweight, 18.71% …

Race & Gender Disparities In The Embedding And Accumulation Of Childhood Poverty On Young Adult Bmi, Daphne C. Hernandez, Emily Pressler

International Journal of Exercise Science: Conference Proceedings

Purpose: A disproportionate number of race/ethnic minorities are both impoverished and overweight compared to white populations. Experiencing poverty during childhood is positively correlated with being obese in adulthood, especially for females. However, it is unclear whether it is the embedding of childhood poverty (i.e. timing of childhood poverty in relation to children’s stage of development) or the accumulation (i.e. duration) of the exposure to childhood poverty which contributes to the race and gender disparities in young adult body mass index (BMI). Method: Data from the 1979 National Longitudinal Study of Youth and the Children and Young Adult file were used …

Whole body vibration (WBV) is a novel tool used to stimulate the neuromuscular system; research indicates it may improve strength, power, and balance in many populations. Purpose: The purposes of this study were to determine if WBV training is feasible in a skilled nursing facility and if standard of care (SOC) with augmented WBV …

Timed Up-And-Go Scores Are Associated With Balance But Not Lower-Extremity Force Production In Elderly Skilled Nursing Facility Patients, Christopher Barnett, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Aging is associated with numerous deleterious muscular, skeletal, and neurologic adaptations that may result in functional performance decrements. These decrements are accelerated during periods of unplanned physical inactivity (e.g. hospitalization). Reductions in gait velocity are well documented in the elderly and may result from fear of falling, poor balance, or inability to accelerate because of reduced ground reaction force capabilities. Purpose: To determine if timed up-and-go scores were related to balance or lower extremity force production in skilled nursing facility patients. Methods: Data were collected on 40 patients (77.1±1.4y; 164.2±1.7cm; 75.3±3.3 kg) in an inpatient skilled nursing facility. The 15 …

The Impact Of Physiologic Reductions In Blood Pressure Upon Oxygen Uptake During Moderate Intensity Leg Cycling, Cory L. Butts, Paul Mcdonough, David Keller, Mitchel Samels, Davor Krnjajic

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Control of oxygen uptake (VO2) during the rest-to-exercise transition is thought to be dominated by intracellular processes rather than oxygen delivery. However, large changes in arterial pressure (i.e., supraphysiologic) have been shown to alter VO₂ and its kinetics. Importantly, no studies have investigated the consequence of physiologic alterations in blood pressure on VO₂ and its kinetics during exercise in humans. PURPOSE: The aim of this preliminary study was to assess the effect of modest reductions in MAP achieved via neck suction upon Vo₂ across the rest-exercise transition, to test the hypothesis that physiologic reductions in arterial …

Vitamin D Status In Lean And Obese Mexican American Children, Nadia H. Agha, Whitney L. Breslin, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Vitamin D deficiency is a worldwide problem amongst adolescents and adults, particularly in minority populations due to high skin melanin content. Melanin blocks the absorption of UVB photons, which limits natural vitamin D accumulation, requiring more dietary intake of vitamin D. Vitamin D deficiency is associated with an increased risk for chronic diseases like cardiovascular disease and diabetes mellitus. Low levels of vitamin D are inversely correlated with systemic inflammation possibly mediating the relationship between vitamin D deficiency and disease. Adequate levels of vitamin D may decrease the risks of chronic diseases, including cardiovascular disease, diabetes mellitus, common cancers, and …

Association Between Anthropometrics, Vertical Jump And Broad Jump To Pure And Transitional Acceleration In Junior College Baseball Players, Casey J. Bollier, Bryan Alexander, A. Eugene Coleman, A. Hatton, Chris Seponski, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Sprint acceleration is a key physical attribute in baseball players that can be characterized by two phases: pure (PURE) and transitional (TRANS) acceleration. In a linear sprint, PURE occurs from the initiation of movement to approximately 15-meters; TRANS acceleration occurs from approximately 15-meters until an athlete reaches top velocity. Since baseball fields are clearly marked at 13.7m (foul-line) and 27.4m (1^st base), acceleration can be determined in a sports-specific environment and these data may be helpful in characterizing player success. Purpose The purpose of this study was to determine the relationship between anthropometrics, vertical, and broad jump ability to …
