Good morning. New research suggests taurine could help unacclimated athletes sweat sooner and stay cooler, Brian Kelly is using AI to prep for his comeback, and a post-workout beer may not be as bad for rehydration as we thought. Let's get into it.

🌡️ Taurine May Help Unacclimated Athletes Handle Heat

Sport scientist Jonah Rosner broke down a new review in Nutrients on X this week. The short version: taurine supplementation may help athletes who aren't heat-acclimated start sweating sooner, sweat more, and keep core temp lower during exercise in the heat.

The proposed mechanism is that taurine may lower the brain's sweating threshold - essentially telling the body to cool itself earlier. Still early evidence, small samples, and lab conditions only. Read More

🤖 Brian Kelly Is Using Claude AI to Prep for His Next Coaching Job

In an interview last week, former LSU and Notre Dame head coach Brian Kelly revealed he's using Claude AI daily to prepare for his next opportunity - researching recruiting profiles, the transfer portal, and broader college football trends. "Every day I'm trying to do my due diligence using Claude and AI," Kelly said. He also drew a distinction between tools: "I think Claude is probably a little better at predicting some things outside the lines, where ChatGPT is much more driven right down the center."

Kelly stopped short of predicting AI takes over the game: "It's not going to take over everything... I think AI, used the right way, can enhance the experience for everybody." Read More

🥚 A 40,000-Person Study Just Made the Case for Eating More Eggs

A new study out of Loma Linda University followed nearly 40,000 adults for over 15 years and found that people who regularly ate eggs had meaningfully lower rates of Alzheimer's disease - and the more eggs they ate, the stronger the association. Researcher William Wallace, Ph.D. broke it down on X, pointing to nutrients in yolks - choline, lutein, zeaxanthin, DHA - as the likely drivers. He was clear it's observational, not a smoking gun.

🍺 Post-Workout Beer: Bad for Performance, Less Bad for Rehydration

Brandon Luu, MD highlighted a study on X that reframes the post-workout beer conversation. Alcohol's effect on performance and recovery is well-documented - that hasn't changed. But the dehydration piece is more nuanced than the conventional wisdom suggests.

Researchers found that full-strength beer spiked urine output more than a sports drink right after exercise. But five hours later, fluid balance wasn't significantly different from water. A post-workout beer is worse than a sports drink for rehydration - but the data suggests it's not the hydration disaster it's often made out to be. Read More
