Japanese Language Podcast: Type of Resistance Exercise and Endothelial Function
Wednesday Jul 18, 2018
Wednesday Jul 18, 2018
In this special Japanese-language podcast, we explore an important exercise physiology question: Can high-intensity resistance exercise, combined with low repetitions, maintain endothelial function? Listen as Associate Editor Masafumi Kitakaze (National Cerebral and Cardiovascular Center, Japan) interviews lead author Takuma Morishima (Hosei University, Japan) and content expert Osamu Tsukamoto (Osaka University, Japan) about the novel work by Morishima and co-authors. By studying young, healthy male volunteers, the authors found that both moderate-intensity resistance exercise with moderate repetitions, and low-intensity resistance exercise with high repetitions caused significant impairment in endothelial function. In stark contrast, the authors found that high-intensity resistance exercise with low repetitions prevents endothelial dysfunction. While these findings offer key insights for young, healthy men participating in resistance exercise programs, what are the implications for older adults, women, and hypertension patients? Listen and find out.

Different Roles of ENaC in Carotid and Mesenteric Arteries

Are ENaC (Epithelial Na+ channels) sheer sensors in arteries? This is the central question we explore in our latest podcast, as Associate Editor Robert Hester (University of Mississippi Medical Center) and content expert Heather Drummond (University of Mississippi Medical Center) interview lead author Martin Fronius (University of Otago, New Zealand) about the intriguing new work by Ashley et al. Fronius and co-authors observed a dilation in vessel diameter in carotid arteries when ENaC was blocked. In contrast, blocking ENaC in mesenteric arteries resulted in vasoconstriction. Does the architecture of the ENaC itself, in endothelial cells compared to smooth muscle cells, affect the response to sheer stress? Listen and find out.
