Correlation Between Allostatic Load And Endothelial Function, Ethan Joergensen, Justo Perez, Jasdeep Kaur

International Journal of Exercise Science: Conference Proceedings

Allostasis refers to the body’s innate adaptive ability to maintain homeostasis following exposure to acute and dynamic stressors. Chronic exposure to physical and/or psychological stress can lead to dysregulation of this stress response mechanism, leading to physiological dysfunction. The aggregate result of these stressors on the body is measured by calculating an individual’s allostatic load (AL), which is a score that represents the magnitude of degenerative stress-related physiological changes present in the body by assessing a variety of pertinent biomarkers and physical measurements. PURPOSE – Our goal in this study was to examine the concept of allostatic overload as it …

Static Stimuli's Impact On Postural Linear Parameters In Children With Autism Spectrum Disorder, Megan E. Perkins, Bryon C. Applequist

International Journal of Exercise Science: Conference Proceedings

Limited or restricted forms of postural control has been reported in children diagnosed with Autism Spectrum Disorder (ASD) in contrast to their neurotypical counterparts. This aligns with the ASD inability to integrate sensory processing properly, thus producing a less adaptive postural response to changes in their environment. Interestingly, although there is a deficit in postural control, visual-spatial perception abilities in those with ASD tend to be advanced. For example, children with ASD have performed well in the block design subtest of the Weschler Intelligence Scale. Additionally, they tend to hyperfocus attention on one item while disregarding the others, another quality …

Effect Of The Physical Inactivity Duration On Postprandial Lipid Metabolism The Morning After Exercise, Jieting Wang, Chelsea Merseal, Hadi Fareed, Remzi Satiroglu, Edward Coyle

International Journal of Exercise Science: Conference Proceedings

In physically active people (e.g., ~8,000 steps/d), an acute bout of exercise improves postprandial fat metabolism when measured the morning after exercise. However, in people who have been inactive for more than two days, the acute bout of exercise does not improve postprandial fat metabolism as reflected by a greater increase in plasma triglyceride concentration and a reduced whole body fat oxidation. This phenomenon whereby fat metabolism is suppressed by prior inactivity is termed ‘exercise resistance’. PURPOSE: The purpose was to determine if shorter periods (i.e., less than two days) of inactivity (i.e., 12, 24, 36 h) induce ‘exercise …
