An Investigation In Muscle Activation During Load Carrying, Sidney Baudendistel 2017 University of Nebraska at Omaha

An Investigation In Muscle Activation During Load Carrying, Sidney Baudendistel

Student Research and Creative Activity Fair

Carrying items is essential to everyday living, but is often reported to be a functional limitation in individuals with respiratory dysfunction. The interaction between breathing and carrying a bimanual load (i.e., carrying an evenly distributed load in each hand) is not well understood and limits the capacity to derive interventions to address functional limitations. The purpose of this study was to examine the effect of two bimanual loads, 10% and 5% of body weight, on gait. Fourteen healthy, young adults walked with and without a load on each wrist (2.5 and 5% of body weight) using wrist weights ...

Analysis Of Food Hub Commerce And Participation Using Agent-Based Modeling: Integrating Financial And Social Drivers, Caroline C. Krejci, Richard Stone, Michael Dorneich, Stephen B. Gilbert

Stephen B. Gilbert

Objective: Factors influencing long-term viability of an intermediated regional food supply network (food hub) were modeled using agent-based modeling techniques informed by interview data gathered from food hub participants.

Background: Previous analyses of food hub dynamics focused primarily on financial drivers rather than social factors and have not used mathematical models.

Method: Based on qualitative and quantitative data gathered from 22 customers and 11 vendors at a midwestern food hub, an agent-based model (ABM) was created with distinct consumer personas characterizing the range of consumer priorities. A comparison study determined if the ABM behaved differently than a model based on ...

Few studies have evaluated the effects of alcohol consumption on the incidence of the metabolic syndrome (MetS). Therefore, the objective of the present study was to examine the association between alcohol consumption and incident MetS in a population of US men. This is a prospective study of 7483 Caucasian men, who were free of the MetS and CVD at baseline. Information was collected on alcohol consumption, health status and fitness level at an initial clinical examination. Additional health information and determination of incident cases of the MetS were obtained at follow-up clinical examinations between 1979 and 2005. Compared with non-drinkers ...


A General Relationship Links Gait Mechanics And Running Ground Reaction Forces, Kenneth P. Clark, Laurence J. Ryan, Peter G. Weyand 2017 West Chester University of Pennsylvania

A General Relationship Links Gait Mechanics And Running Ground Reaction Forces, Kenneth P. Clark, Laurence J. Ryan, Peter G. Weyand

Kenneth Clark

The relationship between gait mechanics and running ground reaction forces is widely regarded as complex. This viewpoint has evolved primarily via efforts to explain the rising edge of vertical force– time waveforms observed during slow human running. Existing theoretical models do provide good rising-edge fits, but require more than a dozen input variables to sum the force contributions of four or more vague components of the body’s total mass (mb). Here, we hypothesized that the force contributions of two discrete body mass components are sufficient to account for vertical ground reaction force– time waveform patterns in full (stance foot ...
