The Acute Effect Of Heat Therapy On Conduit Artery And Forearm Microvascular Function, Iman O. Aldaas, Zachary Martin, Joshua Vu, Natalia Cardenas, Emily Merlau, Jeremiah Campbell, John Kolade, R Matthew Brothers
International Journal of Exercise Science: Conference Proceedings
Heat Therapy (HT) is a practice that has been widely adopted across many cultures for centuries due to its multitude of health-related benefits. In terms of cardiovascular related benefits, HT improves various physiological indices including peripheral vascular function thereby mitigating the decline of arterial health. While studies investigating the effect of heat-therapy on mechanisms of vascular function are becoming more common, the vast majority are conducted following chronic exposure to the heat perturbation (i.e., multiple exposures a week for 2 – 3 months) as opposed to the effect of exposure to an acute bout of HT (i.e., single exposure). Furthermore, …

Effect Of Treadmill Surface Stiffness On The Running Economy Benefits Of A Highly-Cushioned Racing Shoe: A Pilot Study, Zane A. Thornton, Dustin P. Joubert
International Journal of Exercise Science: Conference Proceedings
Running economy (RE) is defined as the oxygen consumption (VO2) at a given running speed. The Nike Vaporfly line of racing shoes, which includes more compliant and resilient midsole foam and a carbon-fiber plate, have been shown to improve RE during treadmill testing. Previous research suggests that RE in general is worse on treadmills with stiffer running platforms. However, it is unclear if the magnitude of the RE benefits provided by these new shoes relative to a control shoe differ based on treadmill stiffness. Given that some treadmill platforms allow more flex or compliance, this may be an …

Exercise Mobilizes Early And Late Differentiated Cd8 T Cells Expressing A Marker Of Exhaustion, Rebekah Hunt, Mahmoud Elzayat, Emily C. Lavoy
International Journal of Exercise Science: Conference Proceedings
T cell differentiation occurs following activation of key functions, such as proliferation and cytokine production. Naïve (NA) and central memory (CM) T cells are early differentiated, whereas effector memory (EM) and RA+ effector memory cells (EMRA) are later differentiated. CD57 expression, a putative marker of exhaustion, has also been used to identify later differentiated cells, although recent data indicate CD57 can also be expressed by NA and CM. Exercise mobilizes EM and EMRA to a greater extent than NA and CM. Separately, exercise has been shown to preferentially mobilize CD57+ cells. Whether these exercise responsive CD57+ cells arise from highly …
