The Claim

In trained male endurance athletes recovering from prolonged exercise-induced dehydration, muscle glycogen resynthesis rates do not differ significantly between low-fluid (400 mL) and high-fluid (3170 mL) carbohydrate rehydration strategies, with glycogen levels reaching approximately 79–87 g/kg dry muscle within 4 hours post-exercise, indicating that fluid availability does not limit glycogen restoration in this population.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

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

Quantitative
1 study reviewed
In plain English

For male endurance athletes who are dehydrated after long workouts, drinking a little or a lot of fluid with carbs doesn’t make a difference in how fast their muscles refill energy stores in the first 4 hours after exercise.

See the scientific wording

In trained male endurance athletes recovering from prolonged exercise-induced dehydration, muscle glycogen resynthesis occurs at a rate that is not significantly different between low-fluid (400 mL) and high-fluid (3170 mL) carbohydrate rehydration strategies, with glycogen levels reaching approximately 79–87 g/kg dry muscle within 4 hours post-exercise, indicating that fluid availability does not limit glycogen restoration in this population.

What the research says

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

    The study found that athletes who drank little or a lot of fluid after dehydration recovered the same amount of muscle fuel (glycogen), so drinking more water didn’t help build more fuel.
