CNN just featured our research, but they got the methods and results wrong! Needless to say, the newsletter is back (and it won't be written by AI).

New research on highly trained athletes highlights that sex differences in maximal oxygen uptake (VO2max) are primarily driven by 2 factors: body composition and hemoglobin.🧵

🧂Our controlled feeding pilot trial suggests potential sex differences in kidney responses to dietary salt. With a high salt diet, females may increase endothelin-1 excretion more. Endothelin-1 is a potent vasoconstrictor peptide and promotes salt excretion by the kidneys.

New research alert!

🌡️ Young and older adults maintained cardiac output in extreme heat. However, older adults relied more on systolic (i.e. pumping) function, yet still struggled to maintain systolic blood pressure.

Great time working with Joe Vondrasek on an @apsphysiology.bsky.social editorial.

We highlighted work from Ridderbos et al. that supports considering pulmonary vascular disease for patient-tailored treatment among patients with a Fontan circulation.

🚨New open-access article!

We found that female aging differentially affects sympathetic blood pressure regulation at rest versus in responses to cold or apneic stress.
