What moved
How to read these marks →- Increases body mass
very limited
“Body mass increased with sodium versus placebo (0.38 [0.02, 0.74] kg; p = .04), with a greater increase in MC Phase 4 (0.69 [0.17, 1.2] kg; p < .001).”
What did not
- No detected effect on core body temperature
very limited
“There were no significant sodium hyperhydration or MC phase effects on rectal temperature or heart rate (p > .05).”
