Spatial Clustering Of Physical Activity And Obesity In Relation To Built Environment Factors Among Older Women In Three U.S. States, Kosuke Tamura, Robin C. Puett, Jaime E. Hart, Heather A. Starnes, Francine Laden, Philip J. Troped
Kinesiology and Public Health
Background
Identifying spatial clusters of chronic diseases has been conducted over the past several decades. More recently these approaches have been applied to physical activity and obesity. However, few studies have investigated built environment characteristics in relation to these spatial clusters. This study’s aims were to detect spatial clusters of physical activity and obesity, examine whether the geographic distribution of covariates affects clusters, and compare built environment characteristics inside and outside clusters.
Methods
In 2004, Nurses’ Health Study participants from California, Massachusetts, and Pennsylvania completed survey items on physical activity (N = 22,599) and weight-status (N = 19,448). The spatial …

Effects Of Barbell Deadlift Training On Submaximal Motor Unit Firing Rates For The Vastus Lateralis And Rectus Femoris, Matt S. Stock, Brennan J. Thompson
Kinesiology and Health Science Faculty Publications
Previous investigations that have studied motor unit firing rates following strength training have been limited to small muscles, isometric training, or interventions involving exercise machines. We examined the effects of ten weeks of supervised barbell deadlift training on motor unit firing rates for the vastus lateralis and rectus femoris during a 50% maximum voluntary contraction (MVC) assessment. Twentyfour previously untrained men (mean age 524 years) were randomly assigned to training (n515) or control (n59) groups. Before and following the intervention, the subjects performed isometric testing of the right knee extensors while bipolar surface electromyographic signals were detected from the two …

The Effects Of An Exercise Program On Cardiovascular Risk Factors At A Faith Based University, Annisa R. Albury, Jacob D. Forsythe, Greggory M. Thorpe
Exercise Science Senior Research Projects
Physical inactivity is a significant risk factor for heart disease, hypertension, stroke, diabetes, and certain types of cancer according to the World Health Organization (WHO, 2013). A simple form of physical activity that improves health and also has a high adherence rate is walking (Dishman, 1994). Walking has been shown to lower fasting blood glucose, decrease total cholesterol, and reduce hypertension when introduced to college faculty and staff as part of a comprehensive wellness program (Haines, 2007). PURPOSE: To determine if a walking program would lower cardiovascular risk factors for faculty and staff who adhere to a faith based values …
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Mahurin Honors College Capstone Experience/Thesis Projects
BACKGROUND: Motor control, learning, and development need to be considered by any coach working with youth athletes. When coaches fail to consider these areas, they may be more likely to create practice plans, which omit the innate physiological and psychological differences between youth and adult participants, lessen the development of sport-specific skills, and may create less enjoyable sporting experiences for young players. PURPOSE: The aims of this literature review were to explore recent scientific literature linking motor behavior/development to application in youth basketball, identify major themes, and summarize these concepts in a manner useful to coaches in this environment. METHODS: …

Kinematics And Economy Of Novel Barefoot Running, Aaron Zell, Patrick Babington
Annual Student Research Poster Session
The purpose of the study was to compare key physiological, anthropometric, and kinematic attributes between barefoot and shod runners while also comparing these variables to the running economy of their respective conditions. We hypothesize that when running in the acute barefoot condition participants will exhibit significant biomechanical, physiological, and kinematic differences compared to the shod condition that may be correlated with a superior or inferior running economy. Male (4) and female (5) test subjects (19.2±0.83 years, 171.06±6.89 cm, 71.09±14.52 kg) participated in two separate testing sessions. The first session involved collecting the weight, height, sitting height, ankle and hip widths, …

Instrumented Figure Skating Blade For Measuring On-Ice Skating Forces, S A. Acuña, D M. Smith, J M. Robinson, J C. Hawks, P Starbuck, D L. King, Sarah T. Ridge, Steven Knight Charles
Faculty Publications
Competitive figure skaters experience substantial, repeated impact loading during jumps and landings. Although these loads, which are thought to be as high as six times body weight, can lead to overuse injuries, it is not currently possible to measure these forces on-ice. Consequently, efforts to improve safety for skaters are significantly limited. Here we present the development of an instrumented figure skating blade for measuring forces on-ice. The measurement system consists of strain gauges attached to the blade, Wheatstone bridge circuit boards, and a data acquisition device. The system is capable of measuring forces in the vertical and horizontal directions …

A Comparative Assessment Of Hand Preference In Captive Red Howler Monkeys, Alouatta Seniculus And Yellow-Breasted Capuchin Monkeys, Sapajus Xanthosternos, Nasibah Sfar, Madhur Mangalam, Werner Kaumanns, Mewa Singh
Journal Articles
There are two major theories that attempt to explain hand preference in non-human primates–the ‘task complexity’ theory and the ‘postural origins’ theory. In the present study, we proposed a third hypothesis to explain the evolutionary origin of hand preference in non-human primates, stating that it could have evolved owing to structural and functional adaptations to feeding, which we refer to as the ‘niche structure’ hypothesis. We attempted to explore this hypothesis by comparing hand preference across species that differ in the feeding ecology and niche structure: red howler monkeys, Alouatta seniculus and yellow-breasted capuchin monkeys, Sapajus xanthosternos. The red …

Metabolic dysfunction in skeletal muscle is a major contributor to the development of type 2 diabetes. Endurance exercise training has long been established as an effective means to directly restore skeletal muscle glucose and lipid uptake and metabolism. However, in addition to the direct effects of skeletal muscle on glucose and lipids, there is renewed interest in the ability of skeletal muscle to coordinate metabolic activity of other tissues, such as adipose tissue and liver. The purpose of this study was to examine the effects of endurance exercise on the expression level of two novel muscle-derived secreted factors, or myokines, …

Feedback based balance control requires the integration of visual, proprioceptive and vestibular input to detect the body’s movement within the environment. When the accuracy of sensory signals is compromised, the system reorganizes the relative contributions through a process of sensory recalibration, for upright postural stability to be maintained. Whereas this process has been studied extensively in standing using the Sensory Organization Test (SOT), less is known about these processes in more dynamic tasks such as locomotion. In the present study, ten healthy young adults performed the six conditions of the traditional SOT to quantify standing postural control when exposed to …

We tested the hypothesis that activation of inwardly rectifying potassium (KIR) channels and Na+-K+-ATPase, two pathways that lead to hyperpolarization of vascular cells, contributes to both the onset and steady-state hyperemic response to exercise. We also determined whether after inhibiting these pathways nitric oxide (NO) and prostaglandins (PGs) are involved in the hyperemic response. Forearm blood flow (FBF; Doppler ultrasound) was determined during rhythmic handgrip exercise at 10% maximal voluntary contraction for 5 min in the following conditions: control [saline; trial 1 (T1)]; with combined inhibition of KIR channels and Na …

Reverse total shoulder arthroplasty (RTSA) is increasingly used in the United States since approval by the FDA in 2003. RTSA relieves pain and restores mobility in arthritic rotator cuff deficient shoulders. Though many advantages of RTSA have been demonstrated, there still are a variety of complications (implant loosening, shoulder impingement, infection, frozen shoulder) making apparent much still is to be learned how RTSA modifies normal shoulder function. The goal of this study was to assess how RTSA affects deltoid muscle moment generating capacity post-surgery using a subjectspecific computational model driven by in vivo kinematic data.

The goal of this study was to assess the sensitivity of the deltoid muscle moment arms as a function of joint configuration for an existing RTSA subject. High variations were found for all three deltoid components. Variation over the entire abduction arc was greatest in the anterior and lateral deltoid, while the posterior deltoid moment arm was mostly sensitive to joint center changes early in the abduction arc. Moment arm changes of 10-16mm represent a significant amount of the total deltoid moment arm. This means there is an opportunity to dramatically change the deltoid moments arms through surgical placement of …
