Does Sodium Endurance Hydration Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Sodium Endurance Hydration Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - This cutoff was selected based on evidence indicating glycogen stress at ~40 min under heat stress. [Salame A (2026); evidence level 1] - Risk of bias was assessed using the Cochrane Collaboration's tool for assessing risk of bias. [Salame A (2026); evidence level 1] - Carbohydrate supplementation resulted in equivocal benefits to endurance performance: five studies found significant ( p Conclusions Carbohydrate intake during endurance exercise in the heat does not consistently improve exercise performance. [Salame A (2026); evidence level 1] - Background and objectives Endurance exercise performance is impaired by heat stress. [Salame A (2026); evidence level 1] - Background: Leading sports medicine and nutrition organizations recommend replacing sodium losses during prolonged exercise; however, practical guidance for implementing sodium replacement strategies remains limited. [Goulet EDB (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
