Really happy to see this published in EJHF. Joey, Chris and I show that middle-aged adults with severe obesity present with absolute hypervolemia, relative hypovolemia and disproportionate LV enlargement. @utswheart @UTSWMedCenter @texashealth @IEEMPHD

Really happy to see our paper published in @JHypertension. @Deoliveiragdc and I show that the BP pressure response to exercise is not different between hypertensive adults with LVH and healthy controls when normalized for VO2.

Happy to share our recent paper published in @JPhysiol that shows, for the first time in humans, that Neuropeptide Y mediated vasoconstriction is sensitive to functional sympatholysis, to a similar degree that is alpha-adrenergic vasoconstriction.

🔥Heat to hypoxia cross-adaptation ⛰️
Our new study shows that 6 weeks of post-exercise hot water immersion (HWI) can boost exercise performance in acute hypoxia. 🚴♂️🛀🔥

Great to see this published in @ExpPhysiol working with Mike Nelson. The paper extends the assessment of central arterial stiffness and wall mechanics (strain and strain rate) from ultrasound to MRI using a cine collected in every cardiac MRI ever taken.
