Map Kinase Phosphatase-5 Regulates Cardiac Adapation To Endurance Exercise, Jaime A. Perales, Dr. Kisuk Min
International Journal of Exercise Science: Conference Proceedings
Endurance exercise induces a beneficial effect on the cardiovascular system and promotes cardio protection against heart disease. It has been established that the mitogen-activated protein kinases (MAPKs) promote the improvement of cardiac function in response to endurance exercise. However, molecular mechanisms of how MAPK signaling pathways regulate cardiac adaptation to endurance exercise remain unclear. The MAPKs are inactivated by MAP kinase phosphatases (MKPs) through direct dephosphorylation. Recently, growing evidence suggests the importance of MKP-5 signaling mechanisms in physiological and pathological processes. Previously, we have demonstrated that MKP-5-deficient skeletal muscle exhibits improved regenerative myogenesis in response to injury and mice lacking …

Exploring The Differences In Stress Mindset Between Former And Current College Student-Athletes, Creighton Avery, Amber M. Shipherd
International Journal of Exercise Science: Conference Proceedings
Stress is a universal experience, often believed to be negative, that has been linked with negative consequences. However, recent studies have shown that stress can lead to positive outcomes as well, including an increase in health and performance in a variety of domains. Research has also found one’s beliefs about the nature of stress (e.g., stress mindset) play a large role in the extent to which one experiences these beneficial outcomes of stress. Although two athletes may encounter the same stressor, their beliefs on stress impact whether they experience detrimental or enhancing outcomes resulting from the stressor. Given some athletes …

International Journal of Exercise Science: Conference Proceedings
Urine epidermal growth factor (uEGF) is a novel biomarker utilized in assessing renal health in various renal diseases, specifically chronic kidney disease (CKD). uEGF promotes multiple intracellular pathways, stimulating renal cell growth, survival, and replication. uEGF production is activated by multiple agonists that bind to the uEGF receptor. Aerobic exercise initiates the upregulation of several of these agonists to increase the production of uEGF. Depending on the mode and intensity of aerobic exercise, uEGF agonists may activate differently in CKD populations. PURPOSE: To determine the influence of an acute bout of steady-state exercise (SSE) and high-intensity interval exercise (HIIE) on …

In the growing world of health and well-being, three-dimensional (3D) scanning is emerging as a popular tool to assess body composition. While body composition cannot be truly “measured” in living humans, it can be approximated. This, however, leads to two types of errors (i.e., technical and biological) in the body composition assessment. PURPOSE: This study was used to determine what percent or range of percentages in body fat one must exceed before concluding a real change has occurred. By conducting assessments on separate days, with only a short period of time between them, true changes in body composition are …

Sex Moderates The Fitness Tests - Performance Index Relationship In Collegiate Basketball: A Case Study, Nicole Kingsley, Samuel Amsbaugh, Zacharias Papadakis, Grant Morgan, Ali Boolani, Andreas Stamatis Dr.
International Journal of Exercise Science: Conference Proceedings
Performance indicators are used widely in sports, including basketball. Those total performance metrics are mathematical models that are used to determine the “best” athlete per game/week/season. Players with higher metrics get recruited more and/or get offered better contracts. During offseason, strength and conditioning coaches (SCCs) perform tests to determine the fitness levels of their players. Although those scores differ by sex, the fitness levels are associated with in-season sport performance and, therefore, performance indices. More insight in the fitness tests - performance index relationship in the collegiate basketball and the differential effects by sex would be valuable for all stakeholders …
