Vascular Responses During Steady-State Exercise In Adults With Type 1 Diabetes, Ruby A. Nyarko, Ashlesha D. Dalve, Justo Perez Iii, Pratima V. Kumar, Jasdeep Kaur

International Journal of Exercise Science: Conference Proceedings

Type 1 diabetes (T1D) is associated with widespread hyperglycemia-induced vascular damage, which affects both conduit and resistance arteries. This damage has been demonstrated by impaired vasodilatory responses to a 5-minute ischemic stimulus (flow-mediated dilation) and infusion of pharmacological vasodilators in patients with T1D. However, whether this vascular impairment affects blood flow regulation during steady-state exercise in T1D remains unclear. PURPOSE: Herein, we tested the hypothesis that adults with T1D would exhibit blunted forearm blood flow (FBF) and forearm vascular conductance (FVC) during steady-state rhythmic handgrip exercise (RHG), compared to age-matched healthy controls. METHODS: We studied 27 adults (15 …

Low-Energy Cooling Strategies To Mitigate Thermal Strain Of Older Adults Exposed To Very Hot-Dry Heat, Isa A. Farooqi, Zachary J. Mckenna, Whitley C. Atkins, Elizabeth A. Gideon, Craig G. Crandall

International Journal of Exercise Science: Conference Proceedings

Extreme heat causes morbidity and mortality, particularly among older adults. Although air conditioning can mitigate heat strain, it may be inaccessible due to limited resources, high costs, or power outages. Consequently, cooling strategies other than air-conditioning are needed to mitigate excessive elevations in core temperature and cardiovascular strain in this population. While electric fans offer a low-cost and widely available intervention, their effectiveness in very hot conditions is minimized due to potential increases in heat gain and dehydration. In contrast, skin wetting is a promising low-cost and energy-free cooling strategy that enhances evaporative heat loss. PURPOSE: We tested the hypotheses …
