The Claim

In trained male endurance athletes who fully rehydrate after prolonged dehydrating exercise, the ratio of muscle water storage to glycogen resynthesis reaches approximately 1:17, indicating that excess water retention during rehydration is not primarily due to glycogen-bound water but may instead result from transient fluid shifts or increased intramuscular hydration.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When male endurance athletes drink enough fluids to fully rehydrate after a long, sweaty workout, their muscles hold onto a lot more water than expected for the amount of fuel (glycogen) they're storing — about 17 parts water to 1 part fuel. This extra water isn't just stuck to the fuel; it might be due to temporary shifts in body fluids or increased hydration inside the muscles.

See the scientific wording

When trained male endurance athletes consume sufficient fluid to fully rehydrate after prolonged dehydrating exercise, the ratio of muscle water storage to glycogen resynthesis increases to approximately 1:17, suggesting that excess water retention during full rehydration is not directly bound to glycogen but may reflect transient fluid shifts or increased intramuscular hydration.

What the research says

1 study
  1. Study: Relationship between muscle water and glycogen recovery after prolonged exercise in the heat in humans

    When athletes drank enough to fully rehydrate after exercise, their muscles held much more water than needed for glycogen storage, suggesting the extra water wasn’t stuck to glycogen but was temporarily held in the muscle.
