Can post-exercise hot-water immersion induce a cross-adaptation effect enhancing exercise performance in acute hypoxia? @PatrickRod_PhD, @LydSimpson, @Justin_lawley, Hecksteden (University of Innsbruck) and Lesmana (@unpofficial_) investigate... 📜 buff.ly/WQm0lcf

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 doi.org/10.1002/ejhf.70037

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. journals.lww.com/jhypertensi…

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. physoc.onlinelibrary.wiley.c… First of many papers in this area from Chris M. Hearon Jr.'s lab at @IEEMPHD (@texashealth) and @UTSWMedCenter. Thanks to our collaborators, Paul Fadel and Scott Davis, on this project.

🚨 Hot off the press! 🔥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. 🚴‍♂️🛀🔥 @sportaerztin @Justin_lawley @LydSimpson @ExpPhysiol shorturl.at/YimFN @waikato

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. doi.org/10.1113/EP092585
