Intravascular Atp And The Regulation Of Blood Flow And Oxygen Delivery In Humans, Anne R. Crecelius, Brett S. Kirby, Frank A. Dinenno

Health and Sport Science Faculty Publications

Regulation of vascular tone is a complex response that integrates multiple signals which allow for blood flow and oxygen supply to appropriately match oxygen demand. Here, we discuss the potential role of intravascular ATP as a primary factor in these responses and propose that deficient ATP release may contribute to impairments in vascular control exhibited in aged and diseased populations.

Vigorous Exercise Effect On Cardiovascular Health, Aryeh Mahana

The Science Journal of the Lander College of Arts and Sciences

Many studies examine the effects of vigorous cardiovascular exercise on the heart. Intense exercise causes frequent muscle contractions in the heart and specific biomarkers that usually signify a myocardial infarction are released into the bloodstream. However, studies indicate that there might not be a correlation between the release of biomarkers and cardiac function. Another study shows that long term vigorous exercise negatively affects the heart by dramatically increasing the mass and volume of the right and left ventricles, thereby resulting in hypertrophy. The cardiac hypertrophy is still evident even after the subjects have stopped exercising. Cardiac hypertrophy results in myocardial …

The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris

Theses and Dissertations--Kinesiology and Health Promotion

For decades strength and conditioning professionals have been seeking optimal training volumes and intensities to yield maximum performance outcomes without the onset of injury. Unfortunately, current studies apply experimental training techniques without considering the individuals’ response to the imposed training load. Due to the vast genetic variability and extraneous environmental factors that affect one’s ability to recover, results from such studies are controversial and inconclusive. Athlete monitoring systems offer an objective assessment that is purported to evaluate an individual’s physiological readiness to adapt to an overload stimulus and thus allow for daily manipulations in training loads (i.e., fluid periodization). However, …

Investigating The Effects Of Alternative Footwear On Balance, David S. May

Honors Theses

Falls are one of the leading causes of injuries and unintentional deaths in the United States, with 27,800 fatalities attributed to falls in 2012 (National Safety Council, 2014). With two thirds of our body mass located two thirds of our body height above the ground, humans require constant work from balance control systems to prevent these falls (Winter, 1995). Because shoes can alter somatosensory input from the mechanoreceptors on the bottom of the foot and affect these balance control systems (Menant et al, 2008), they must be taken into account when looking into the causes of falls. Traditional footwear designs …

Correlations Between White Matter Integrity, Structural Connectivity, And Upper And Lower Extremity Motor Function In Individuals With Chronic Stroke, Denise M. Peters

Theses and Dissertations

Great variability is seen in the clinical manifestation of and recovery from stroke. Structural abnormalities often extend beyond the infarction site, indirectly affecting nonlesioned areas which can further contribute to motor deficits. Advances in neuroimaging have enabled the examination of white matter integrity and anatomical connectivity within the brain. Evidence is limited, however, regarding the relationship between the structural integrity and connectivity of primary and secondary motor tracts/brain regions and chronic upper and (especially) lower extremity motor impairments post-stroke. Therefore, the current study examined the relationship between upper/lower extremity motor impairments and structural integrity (Aim 1) and connectivity (Aim 2) …
