Resumen
El texto original del estudio, en el idioma en que se publicó.
Passive heating has emerged as a therapeutic intervention for the treatment and prevention of cardiovascular disease. Like exercise, heating increases peripheral artery blood flow and shear rate, which is thought to be a primary mechanism underpinning endothelium-mediated vascular adaptation. However, few studies have compared the increase in arterial blood flow and shear rate between dynamic exercise and passive heating. In a fixed crossover design study, 15 moderately trained healthy participants (25.6 ± 3.4 yr) (5 female) underwent 30 min of whole body passive heating (42°C bath), followed on a separate day by 30 min of semi-recumbent stepping exercise performed at two workloads corresponding to the increase in cardiac output (Qc) (Δ3.72 L·min-1) and heart rate (HR) (Δ40 beats/min) recorded at the end of passive heating. At the same Qc (Δ3.72 L·min-1 vs. 3.78 L·min-1), femoral artery blood flow (1,599 mL/min vs. 1,947 mL/min) (P = 0.596) and shear rate (162 s-1 vs. 192 s-1) (P = 0.471) measured by ultrasonography were similar between passive heating and stepping exercise. However, for the same HRMATCHED intensity, femoral blood flow (1,599 mL·min-1 vs. 2,588 mL·min-1) and shear rate (161 s-1 vs. 271 s-1) were significantly greater during exercise, compared with heating (both P = 2max); however, exercise performed at a higher intensity (53% V̇o2max) results in significantly larger shear rates toward the active skeletal muscle.NEW & NOTEWORTHY Passive heating and exercise increase blood flow through arteries, generating a frictional force, termed shear rate, which is associated with positive vascular health. Few studies have compared the increase in arterial blood flow and shear rate elicited by passive heating with that elicited by dynamic continuous exercise. We found that 30 min of whole body passive hot-water immersion (42°C bath) increased femoral artery blood flow and shear rate equivalent to exercising at a moderate intensity (∼57% HRmax).
