Introduction

Many wheelchairs are donated to developing countries without proper consideration of physical, cultural, and social needs¹. Many children in wheelchairs around the world are unable to self-propel and are dependent on assistants to push their wheelchairs. Organizations designing wheelchairs for low-income countries are eager for outcomes research to inform design. We are performing a set of comparative tests on two pediatric wheelchairs designed for …

International Journal of Exercise Science: Conference Proceedings

Background: Obesity is an independent risk factor for chronic disease. The prevalence of obesity is especially high among Mexican-American children. Peripheral blood monocytes contribute to systemic inflammation and may mediate the relationship between obesity and chronic disease. Obesity affects monocytes and the circulating levels of cytokines/chemokines that influence monocyte behavior. Purpose: investigate alterations in blood monocytes and plasma cytokines/chemokine levels among healthy weight (zBMI ≤ 85th percentile; N=66), overweight (zBMI=85^th-95^th percentile; N=23), and obese (zBMI ≥ 95th percentile; N=39) Mexican-American children. Methods: Blood samples were analyzed for total monocyte concentration, pro-inflammatory monocyte concentration, and classic …

Southern Methodist University, Locomotor Performance Laboratory, Department of Applied Physiology and Wellness, Dallas, TX 75205

Introduction: The metabolic energy cost of human walking has been extensively studied. However, whether men and women require the same amount of energy (per kg of body mass) to walk at the same speed or cover the same distance remains unresolved. While most predictive algorithms incorporate only body mass and walking speed, we have recently found that mass-specific walking metabolic rates are inversely related to stature. Objective: We tested …

Psychological Needs Mediate The Relationship Between Physical Exertion Barriers And Body Fat Percent In College-Aged Mexican-American Women, Vanessa M. Martinez, Jared Montoya, Cody Cox, Alexis Martinez, David Wittenburg

International Journal of Exercise Science: Conference Proceedings

In the last several decades, there has been a wave of interest in the overweight/obese population in the United States. However, little research has focused on the association between exercise barriers and psychological needs in college-aged Mexican-American females. PURPOSE: To investigate the relationships between exercise barriers, psychological needs for exercise, and obesity among college-aged Mexican-American females. METHODS: Body fat measures were recorded on 91 female students (M = 22.8±5.1). The Exercise Benefits and Barriers Scale (EBBS) was used to determine perceived barriers. The EBBS examined Exercise Milieu (EM), Time Expenditure (TEB), Physical Exertion (PEB), and Family Discouragement (FDB) for perceived …

Classification of First Author: Doctoral Student

Introduction: The application of ground force is widely recognized as the critical determinant of running speed. At maximal speeds, 90-98% of the total force applied is directed vertically into the running surface while horizontal (fore-aft) contributions are relatively small. Despite their small magnitude, horizontal forces are clearly essential for balance and may be important for other reasons. However, the pattern of horizontal …

Ground-Based Model for Lunar Disuse Bone Loss

During spaceflight, astronauts are susceptible to decrements in bone mineral density. This suscetibility leaves astronauts at an increased risk of fracture and compromises their likelihood of repeat missions. Our ground-based Lunar model simulates disuse bone loss. Through our novel exercise regimens, we were able to mitigate losses seen by group members not exercised.

International Journal of Exercise Science: Conference Proceedings

Purpose: While it is known that exercise improves health by reducing systemic inflammation, potential mechanisms remain to be elucidated. The purpose of this study is to examine the influence of fitness and adiposity on the anti-inflammatory melanocortin system as a potential mechanism by which exercise reduces inflammation. Methods: Forty-one men and women (35-55yr), who were free from cardiovascular disease, inflammatory disorders, and not taking medications that affect inflammation, were recruited. Participants were questioned about exercise habits and medical history; then completed testing for body composition and aerobic fitness (VO₂max). Subjects were classified as lean/fit (LF, n=14), overweight/fit (OF, …
