Executive Function Relationships To Sitting Time And Physical Activity: A Pilot Study, Megan E. Mcclendon, Mark D. Faries, Jessica Thompson, Danielle Cofield

International Journal of Exercise Science: Conference Proceedings

Executive function (EF) refers to the neurocognitive perspective of supervisory abilities to self-regulate during goal-direct behavior. More specifically, the ability to attend to and inhibit dominant responses (i.e. Attention/Inhibition) has been found to moderate the intention and physical activity (PA) relationship, yet does not appear to relate to PA. However, this EF is related to other health behaviors, such as smoking and alcohol consumption (i.e. behaviors to be inhibited). The lack of relationship to PA might be due to it being a behavior that is not to be inhibited, compared to a behavior that should be inhibited (e.g. sitting time). …

Releasing The Anti-Inflammatory Potential Of Paralysed Skeletal Muscle: The Circulating Cytokine Response To Voluntary Upper-Limb Exercise With/Without The Addition Of Functional Electrical Stimulation (Fes)-Evoked Lower-Limb Contractions, Thomas Aw Paulson, Victoria L. Goosey-Tolfrey, Brett M. Smith, Nicolette C. Bishop

International Journal of Exercise Science: Conference Proceedings

Skeletal muscle is a rich store of inflammatory mediating ‘myokines’. Following release from contracting muscle, the myokine interleukin-6 (IL-6) promotes a circulating anti-inflammatory environment associated with a reduced risk of cardiovascular disease (CVD). The metabolic and functional consequences of lower-limb paralysis, including the gain in relative adiposity and physical inactivity, result in a high prevalence of CVD in individuals with a spinal cord injury (SCI). However, the magnitude of any contraction-induced myokine response in this population may be limited by the small active muscle mass of the upper-limb. The combination of voluntary, upper-limb exercise and involuntary, functional electrical stimulation (FES)-evoked …

Exercise Knowledge, Exercise Beliefs, Physical Activity Engagement And Physical Function In Older Adults, Nicole E. Priest, Amy M. White, James B. Geeslin, Matthew J. Garver, Libby E. Mccurley

International Journal of Exercise Science: Conference Proceedings

Historically, recall surveys have been used to gather information about exercise knowledge and beliefs (EKB) and physical activity (PA). There seems to be a disconnect between what people know and believe about exercise and the choices they make about engaging in exercise. Advancements in the capacity to capture verifiable PA data have greatly improved with application of accelerometers. The ability to objectively verify PA makes reexamining the relationship between EKB and both PA and physical function (PF) worthwhile. The aim of this investigation was to revisit the relationship between EKB and PA and PF in older adults using recall surveys …

Minority and low socioeconomic status groups have the highest rates of overweight and obesity. Children from these families face a greater risk for weight-related health problems such as diabetes, heart disease and cancer as compared to their non-minority and more affluent peers. Factors from the larger physical, social, and cultural environments, and within families, influence weight status among children. Many of these factors are yet to be identified and relationships among known factors are complex and not well understood. The National Institutes of Health and U.S. Department of Agriculture have proposed a research agenda for social and behavioral scientists to …

Using The Para To Evaluate Physical Activity Resource Attributes In Houston And Austin, Tx, Heather J. Adamus, Scherezade K. Mama, Rebecca E. Lee

International Journal of Exercise Science: Conference Proceedings

Many adults do not achieve recommended levels of physical activity (PA), and ecologic models suggest that environmental factors such as physical activity resources (PARs) may influence PA participation. Attributes of PARs, such as accessibility, features, amenities and incivilities, are related to PA. The Physical Activity Resource Assessment (PARA) is an environmental audit tool to assess the type, size, accessibility, incivilities, amenities and features of a PAR. Using the PARA to explore how incivilities and quality of features and amenities differ by location, size or accessibility is an essential step in understanding which attributes influence PA.
