How to read these marks →- Increases serum sodium concentration
very limited
“Plasma sodium concentration increased in both trials, but to a greater extent in SODIUM at 2.5 hours (mean [SD]: 4 [4] mmol·L-1 vs 1 [5] mmol·L-1; P < .05) and postexercise (4 [3] mmol·L-1 vs 1 [5] mmol·L-1; P < .05).”
- Population
- Nine healthy participants (7 male, 2 female) during two 5-hour treadmill runs in the heat; change in plasma sodium at 2.5 hours and postexercise
What did not
“No effect of sodium replacement was observed for heart rate, rectal temperature, thermal comfort, perceived exertion, or physiological strain index.”
- No detected effect on core body temperature
