Abstract

Context: Sweat rate and sweat electrolyte concentration are traditionally collected for one exercise bout. The purpose of this study determined whether sweat electrolyte concentration and sweat rate varies between two modes of exercise. Methods: Twenty subjects (10 male/ 10 female) completed 2 training sessions, one hour of biking and one hour of running in a thermal neutral environment. Sweat samples by absorbent patches were used and collected at the end of exercise or when the sweat patches became full. Results: No differences in sweat rate (Bike = 1.12L/hr ± 0.58, Run 1.12L/hr ± .55, r(38)=.80, p = 1.00) but a significant difference between sex (Bike males = 1.52 ± .49, Bike females = 0.72 ± .36, Run males = 1.57 ± .35, Run females = 0.67 ± .23, p = +, Cl-, K+). Conclusion: Total sweat electrolyte concentration and sweat rate does not change during running or biking.
