Sweat chloride concentration
Prototype vs. reference method (regional absorbent patch technique) during exercise
Time frame: 1.5 hours in sessions 1-6
Regional sweating rate
Prototype vs. reference method (gravimetry using the regional absorbent patch technique) during exercise
Time frame: 1.5 hours in sessions 1-6
Whole body sweating rate
Prototype vs. reference method (changes in nude body mass corrected for fluid intake, urine output, respiratory water loss, and metabolic mass loss) during exercise
Time frame: 1.5 hours in sessions 1-6
Whole body sweat chloride concentration
