Do carbs during exercise spare muscle glycogen? I used to say no, but our new meta-analysis shows a small but significant effect that has likely been masked by small sample sizes. journals.physiology.org/doi/…

🚴‍♂️ New open-access paper from our group out in EJAP! We show durability of the moderate-to-heavy intensity transition (VT1) during prolonged cycling can be predicted using simple, readily available markers of physiological decoupling. (1/7) 📄 doi.org/10.1007/s00421-025-0…

Exercise prevents the seasonal decline in vitamin D metabolites (even when energy balance is maintained!) New RCT from @olyjperkin @drdylanthompson @SophieDaviesRD advanced.onlinelibrary.wiley… Thread👇 May be of interest @theproof @hubermanlab @NutritionDanny @petabeeuk

Congratulations Andrew Barrett on your first publication! Continuing our durability work... Prolonged running reduces speed at the moderate-to-heavy intensity transition without additional reductions due to increased eccentric load link.springer.com/article/10… @EJAP_official

Running speed at VT1 declined following prolonged running in both trials (~6-8%), with no differences between-trials

These results suggest, at least in the protocol used, that adding eccentric load via downhill running did not exacerbate the reduction in running speed at the moderate-to-heavy intensity

A new review digs into the science of "lactic acidosis" and muscle fatigue. Key points: - we don't have "lactic acid" in the body, we have lactate and hydrogen ions, which have separate (and sometimes opposite) effects - lactate is a useful fuel and doesn't cause fatigue [...]

Data from 120,000 runners shows that slow and fast marathoners do essentially the same amount of medium and hard training, but vastly different amounts of easy training. But does that really mean that slow marathoners would get faster by training easier? outsideonline.com/health/tra…

The One Weird Trait That Separates Faster Marathoners from Slower Ones

New data shows that the biggest difference between elite and middling runners is how much time they spend jogging

We are thrilled to see this one published just in time for Christmas! Carbohydrate ingestion during prolonged exercise blunts the reduction in power output at the moderate-to-heavy intensity transition Congrats @Harrison7738800 @CarynZinn @theplews1 pubmed.ncbi.nlm.nih.gov/3970…

Carbohydrate ingestion during prolonged exercise blunts the reduction in power output at the...

These data suggest that durability of the moderate-to-heavy-intensity transition is improved with carbohydrate ingestion. This has implications for training programming and load monitoring.

So, carbohydrate ingestion during prolonged cycling improved durability of the moderate-to-heavy transition Based on previous data, we think this effect is unlikely related to preservation of muscle glycogen, and instead may be related to better preservation of blood glucose

To help with physiologically-based training programming and load monitoring, we need to develop tools that appreciate the reduction in power output at thresholds over time as exercise progresses, and account for the effects of nutrition
