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.
