THE GTGF KNOWLEDGE STANDARD
We write for athletes who want to understand what they are doing. Every new article therefore includes a concrete learning goal, practical actions, common mistakes, a safety boundary and sources appropriate to the claim.
Consensus statements, systematic reviews and primary sports science take priority. Practical guidelines are identified as such.
A training zone, carbohydrate recommendation or recovery measure always receives context: sport, duration, level, conditions and individual response.
After the mechanism comes what you can actually test, measure or adjust in the coming week.
Health, injury and supplement topics include a clear boundary where general sports information ends.
