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.🧵 #ExercisePhysiology #VO2max #SexDifferences #Hemoglobin #SportsScience #AthletePerformance #Research

🚨 Big news! CNN highlighted the work of Dr. Joseph Watso in its feature on the heart-boosting benefits of fast walking. CNN’s article: edition.cnn.com/2025/08/11/h... Original study: journals.physiology.org/doi/epdf/10.... #FSU #Longevity #PublicHealth #ResearchSpotlight

Thanks to Dr. Mike Axler for hosting me on the Simple Science Podcast. We talk about cardiovascular research, ultramarathons, and much more. ❤️🔬🏃 www.youtube.com/watch?v=vbAz...

What's a smart scale? Should you use one? What do you need to know about your body composition besides your weight? APS member Austin Robinson (@ausrob-phd.bsky.social) weighed in 😜 on the subject. Read more from @NBCNews: ow.ly/sKMo50WQuEz #ISpyPhysiology 🧪

🧂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.

🔥 How does your heart handle the heat as you age? New research co-authored by Dr. Joseph Watso reveals that older adults adapt differently to extreme heat, relying more on heart function to stay cool, but facing greater risks to blood pressure and heart health. #FSUResearch #HealthyAging

🚨 New publication alert! Dr. Joseph Watso and student researcher Joseph Vondrasek co-authored a new study examining how ultramarathon running impacts cardiovascular health across the lifespan. Read the full article here: link.springer.com/article/10.1...

🔥 How does the heart handle heat with age? This research brings new clarity to how aging hearts respond to extreme environmental stress. Full study here: journals.physiology.org/doi/abs/10.1... #AgingAndHeat #HeartHealth #HealthyAging #FSUResearch #ISLDigest #CardiovascularPhysiology

🚨New publication alert Central blood pressure and arterial stiffness among ultramarathon runners across the lifespan link.springer.com/article/10.1...

🚨 New publication alert! Dr. Joseph Watso co-authored an editorial with Joe Vondrasek highlighting research on advanced phenotyping in patients with a Fontan circulation. Read more below: journals.physiology.org/doi/abs/10.1... #CardiovascularHealth #ISLDigest #FSUResearch

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. journals.physiology.org/doi/abs/10.1...

If you exercise outside in the summer, we hope you're protecting yourself with sunscreen. Don't worry, it's not going to affect your workout, and it won't make you overheat. Find out why in a vintage #ISpyPhysiology post by @joewatso.bsky.social‬: ow.ly/FqLC50Wtuc5#ISpyPhysiology🧪

Great time working with Joe Vondrasek on an @apsphysiology.bsky.social editorial. journals.physiology.org/doi/abs/10.1... We highlighted work from Ridderbos et al. that supports considering pulmonary vascular disease for patient-tailored treatment among patients with a Fontan circulation.

Thanks for having me on!
