Subjects were less hypo hydrated after consuming high sodium compared to lower sodium concentrations.
High sodium intake may help athletes maintain better hydration levels during extended exercise.

so that subjects were less hypo hydrated after 240 min (0.19 ±0.27 vs. 1.23 ±0.27 vs. 1.18 ±0.27%; P<0.05 for HS, MS & LS).
Why this rating
The study provides statistical significance for hydration differences.

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
