Blood Pressure Variability In Young Male Adult Habitual Vapers, Rie V. Conley, Claire E. Kissell, Ziba Taherzadeh, Danny Dubroy, Benjamin E. Young, Ziyad Ben Taleb, Paul J. Fadel

International Journal of Exercise Science: Conference Proceedings

The use of e-cigarettes (i.e., vaping) has risen dramatically in the last few years. Vaping is more appealing and accessible to young people than traditional smoking. The ease of use can increase the frequency of vaping, which may increase the amount of nicotine consumed. Nicotine is a potent vasoconstrictor that may also affect blood pressure (BP). Indeed, previous studies have shown that traditional cigarette smoking increases BP variability. This is noteworthy because elevated BP variability has been shown to predict future development of cardiovascular disease. However, whether habitual vaping influences BP variability remains unknown. PURPOSE: To test the hypothesis …

Release Of Microrna15a/16 From Skeletal Muscle During Exercise Regulates Proteostasis In Muscle And Cancer, Patrick Ryan, Selina Uranga, James D. Fluckey

International Journal of Exercise Science: Conference Proceedings

Proteostasis, the intricate process of maintaining the proteome, is a critical matter for cellular health. The regulation of the multiple intersecting metabolic pathways comprising the proteostatic network is correspondingly complex and incompletely understood; however, a new and intriguing candidate in understanding this process has emerged in the form of microRNA (miRNA), small RNA species which are capable of regulating hundreds of genes at once by binding to and degrading mRNA transcripts. We have previously shown that muscle contraction results in the release of two miRNA species (miR15a/16) from skeletal muscles, and that a perfusate rich in these miRNAs slows growth …

Effects Of Continuous Aerobic Exercise On Skeletal Muscle Atrophy Induced By Heart Failure, Carolina Tonon, Bertha F. Polegato, Quinten Pigg, Dillon Harris, Aaron Garcia, Daniela S. Inoue, Mariana Janini Gomes

International Journal of Exercise Science: Conference Proceedings

Heart failure is a common and severe disease that worsens morbidity, mortality, and quality of life. One of the clinical manifestations of heart failure is peripheral muscular atrophy, whose presence impacts the prognosis of heart failure patients. Inflammation is one of the main mechanisms related to muscle atrophy. We hypothesized that inflammation, through excessive activation of the Nlrp3 inflammasome, would be tightly associated with skeletal muscle atrophy induced by heart failure. Additionally, aerobic exercise, well known for its anti-inflammatory action, would counteract this condition in a rat model of heart failure. PURPOSE: We aimed to evaluate the effects of continuous …
