Passive Hyperthermia Therapy Similarly Reduces Arterial Blood Pressure In Obese Type 2 Diabetic And Healthy Individuals, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
Diabetes which is associated with impaired glycemic control, can damage macro and microvasculature, and impair vascular relaxation (i.e., endothelial dysfunction). The high thermal conductance of hot water will cause thermoregulatory adjustments that increase cardiac output, heart rate and stroke volume while reducing central venous pressure. This project tested the hypothesis that an acute bout of hot water hyperthermia will reduce arterial blood pressure during and following the exposure, but the response will be attenuated in obese type 2 diabetics. Eleven obese type 2 diabetics (T2D) (50.1 ± 12 y, 45 ± 7.1% fat mass, 7.5 ± 1.8% HbA1C) and nine …

Multiple sclerosis (MS) is marked by conduction abnormalities within the central nervous system that can lead to impaired blood pressure regulation. However, the impact of this disease on dynamic neural control—responsiveness and timing (i.e., latency)—of blood pressure has not been examined. Utilizing a variable neck chamber system, we tested the hypothesis that patients with MS (MS: n=4) exhibit an altered response following baroreflex perturbation compared to sex and age matched healthy controls (CON: n=4). At rest, 5-sec pulses of neck suction (NS; -60 Torr) and neck pressure (NP; +40 Torr) were applied to simulate carotid hypertension and hypotension, respectively. Mean …
