Exercise In Individuals With Down Syndrome: A Brief Review, Rachel L. Kerstiens, Matt Green

International Journal of Exercise Science

International Journal of Exercise Science 8(2): 192-201, 2015. Research examining acute and long-term responses to exercise of individuals with Downs Syndrome (DS) is sparse. However, if this group experiences benefits associated with improved quantity or quality of life, it would be important to elucidate specific responses and discourage adoption of a sedentary lifestyle in individuals with DS. Specifically, these individuals have multiple blunted physiological responses to exercise both at the onset and termination of an acute exercise bout. Mechanistically, this could be rooted in hormonal responses which are blunted, in comparison to non-DS participants. Specific studies indicate individuals with …

International Journal of Exercise Science: Conference Proceedings

Non-alcoholic fatty liver disease (NAFLD) represents a continuum that begins with accumulation of lipid in hepatic cells progressing to hepatic steatosis with inflammation (steatohepatitis), fibrosis, and cirrhosis. Weight-loss using dietary modification and physical activity are common strategies used for the treatment of NAFLD; however, it remains to be determined the effects of physical activity on hepatic inflammation during weight-loss. The purpose of this study was to determine the therapeutic role of physical activity on plasma and hepatic inflammatory markers during weight-loss. Male C57BL/6 mice were fed either a low-fat (LFD; 10% kcal fat) or high-fat (HFD; 60% kcal fat) diet …

The Effects Of Physical Activity On Hepatic Lipid Metabolism During Weight-Loss, Kaylee Poole, Andrew Seija, Kevin Eck, Matthew Harris, Tayler Nick, Joshua S. Wooten

International Journal of Exercise Science: Conference Proceedings

Non-alcoholic fatty liver disease (NAFLD) develops as a result of physical inactivity and overnutrition. Changing dietary behaviors and increasing physical activity are common strategies used for weight-loss; however, it remains unclear what additional benefits are provided by incorporating physical activity in a weight-loss program for the treatment of NAFLD. The purpose of this study was to determine how physical activity reduces hepatic steatosis and changes the expression of hepatic lipogenic genes during weight-loss. Male C57BL/6 mice were fed either a low-fat (LFD; 10% kcal fat) or high-fat (HFD; 60% kcal fat) diet for 10-weeks. Following 10-weeks, the HFD group was …

Effect Of Nitric Oxide Bioavailability On Cutaneous Microvascular Function In Healthy Young African Americans, Kiyoung Kim

International Journal of Exercise Science: Conference Proceedings

We have recently demonstrated impaired microcirculatory function in healthy young African Americans (AAs) as indexed by attenuated cutaneous vasodilation during local heating. The mechanisms resulting in this impairment are multifactorial; however, recent evidence suggests that decreased nitric oxide (NO) bioavailability is a primary contributor. PURPOSE: To expand our previous findings and determine if this reduced microvascular vasodilatory response in AAs is related to a decrease in NO bioavailability. We hypothesized that NO dependent cutaneous vasodilation in response to local heating is lower in healthy young AAs relative to age / sex / body mass matched Caucasians (CA). METHOD: To date …

3-Nitrotyrosine And Soluble Vascular And Intracellular Adhesion Molecule Responses To High-Intensity Interval And Steady-State Moderate-Intensity Exercise, Jeffrey S. Forsse, Zacharias Papadakis, Annie A. Bane, J. Kyle Taylor, Li Qian, Flor Elisa Morales Marroquín, Peter W. Grandjean

International Journal of Exercise Science: Conference Proceedings

Vascular endothelium may respond differently to high-intensity interval exercise (HIIE) when compared to moderate-intensity steady state exercise (SSE). We hypothesized that greater sympathetic stimulation of soluble vascular adhesion molecule-1 (sVCAM-1) and intracellular adhesion molecule-1 (sICAM-1) and greater oxidative and nitrative stress on the vascular endothelium may transiently result from HIIE. PURPOSE: Determine the influence of HIIE on sVCAM-1, sICAM-1 and 3-nitrotyrosine (NT), a marker of nitric oxide-dependent reactive nitrogen species and nitrative stress, relative to a comparable amount of moderate-intensity SSE and a dose that is half that of SSE. METHODS: Seventeen male participants (age 27.8 + 6.4 yr; weight …

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 …

Changes In Creatine Phosphokinase Isoenzymes After Varying Levels Of Resistance Exercise, Ashley Lamar, Yunsuk Koh, Jin K. Park, Farzana Alam

International Journal of Exercise Science: Conference Proceedings

Creatine phosphokinase (CK) isoenzymes are found in various tissues, such as skeletal muscle (CK-MM), cardiac muscle (CK-MB), and the brain (CK-BB). Elevated CK isoenzymes indicate damage or injury to specific tissue. Using CK isoenzymes as a marker in order to indicate muscle damage as a result of different degrees of resistance exercise has not been clearly examined. Purpose: To determine the changes in CK isoenzymes following resistance exercise at different intensities. Methods: Ten healthy recreationally resistance-trained (at least 3 - 6 days per week for a minimum of one year) men participated in the study. The participants performed …

Leg Lean Mass Adaptations Following Short-Term Barbell Training In Women, Jacob A. Mota, Matt S. Stock, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson

International Journal of Exercise Science: Conference Proceedings

Participation in a resistance training program results in both neural adaptations and increases in lean body mass, the latter of which is considered a slow process. The majority of previous investigations that have examined the time course associated with muscular adaptations have utilized exercise machines or single-joint movements. Furthermore, the adaptations associated with resistance training in women are not as well understood as those for men. The purpose of this investigation was to examine the effects of a four week resistance training intervention on changes in leg lean mass in untrained, college-aged women. Thirty-five women (mean ± SD age = …
