Sensitivity Of Prescribing High-Intensity, Interval Training Using The Critical Power Concept, Robert W. Pettitt, Ashley M. Placek, Ida E. Clark, Nicholas A. Jamnick, Steven R. Murray
International Journal of Exercise Science
International Journal of Exercise Science 8(3): 202-212, 2015. The critical power (CP) concept enables the calculation of time to exhaustion (tLIM) for a given power output above CP using the equation of tLIM = W’/(power – CP), where W’ is the curvature constant, and CP is the asymptote for the power-tLIM relationship. The CP concept offers great promise for prescribing high-intensity interval training (HIIT); however, knowledge on the concept’s sensitivity is lacking (i.e., how much of a difference in W’ expenditure is needed to evoke different metabolic responses). We tested if two …

The Positive Effects Of Acute Resistance Exercise On Blood Lipid Profiles In College-Aged Men, Farzana F. Alam, Jin K. Park, Neil A. Schwarz, Ashley P. Lamar, Yunsuk Koh
International Journal of Exercise Science: Conference Proceedings
Low- to moderate-intensity exercise has been widely recommended for people at any age to improve cardiovascular health due to its positive effects on blood lipids and lipoproteins. Recently, many people have been participating in not only low- to moderate-intensity, but high-intensity exercise as well in order to improve their cardiovascular health. However, it is unclear whether high-intensity exercise, particularly resistance exercise, can positively influence blood lipids and lipoproteins. Purpose: The current study examined the effects of low- and high-intensity of resistance exercise on changes in blood lipids and lipoproteins. Methods: In a randomized, cross-over design, 10 healthy recreationally resistance-trained (at …

Role Of High-Intensity Resistance Exercise In Vascular Inflammation In Recreationally Trained Men, Jin K. Park, Neil Schwarz, Darryn Willoughby, Yunsuk Koh
International Journal of Exercise Science: Conference Proceedings
Soluble intracellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) are known as vascular inflammatory markers and play a key role in the development of atherosclerosis. Although low to moderate intensity exercise may positively influence inflammatory markers, the role of high-intensity resistance exercise in sICAM-1 and sVCAM-1 has not been fully examined. The current study examined the effects of resistance exercise at different intensities (low vs. high) on acute responses of sICAM-1 and sVCAM-1. In a randomized, cross-over design, 10 recreationally trained (resistance-trained 3 to 6 days per week for at least one year) college-aged men performed a …

International Journal of Exercise Science: Conference Proceedings
The severity of a concussion is determined by the magnitude of the force of impact and the symptoms expressed post-injury. The most current and widely used test to identify a concussion in college athletics is called the Immediate Post Concussion Assessment and Cognitive Testing (ImPACT). It is a computerized neurocognitive test battery that measures different cognitive abilities and compares baseline with post-injury results. In the current study we formulated a series of physical and psychological cognition tests that measure similar cognitive abilities as the ImPACT. The purpose of this study is to demonstrate that physical tests paired with neurocognitive tests …

The Effect Of Multiple Sclerosis On Carotid Baroreflex Control Of Heart Rate And Blood Pressure, Dustin R. Allen, Mu Huang, David M. Keller, Scott L. Davis
International Journal of Exercise Science: Conference Proceedings
Multiple sclerosis (MS) is marked by conduction abnormalities within the central nervous system that can lead to impaired blood pressure regulation. However, the impact of this disease on dynamic neural control—responsiveness and timing (i.e., latency)—of blood pressure has not been examined. Utilizing a variable neck chamber system, we tested the hypothesis that patients with MS (MS: n=4) exhibit an altered response following baroreflex perturbation compared to sex and age matched healthy controls (CON: n=4). At rest, 5-sec pulses of neck suction (NS; -60 Torr) and neck pressure (NP; +40 Torr) were applied to simulate carotid hypertension and hypotension, respectively. Mean …

Effects Of Acute Cold Exposure On Plasma Biomarkers Associated With Cardiovascular Disease Risk, Michael A. Levi, Jeremy Garcia, Steven Stelly, Donovan Fogt
International Journal of Exercise Science: Conference Proceedings
Background and Aims: The underlying cause of the majority of the cases of CVD is atherosclerosis, which is a condition initiated and progressed by chronic inflammation and hyperlipidemia. We are interested in evaluating the efficacy of cold-exposure to increase shivering- and non-shivering thermogenesis energy expenditure (RMR) as a non-pharmaceutical weight loss tool analogous to low intensity exercise. Naturally, we are concurrently evaluating the possible effects of cold exposure on risk factors associated with CVD risk. Inflammatory cytokines and lipid mediators are used as biomarkers for CVD risk. This proposed study aims to measure cardiovascular inflammatory and lipid biomarkers to expand …
