Intervention type: OTHER
Group type: PLACEBO_COMPARATOR
Intervention: Beverage. Incomplete block where each participant will complete 3 of the 6 possible glycerol-sodium blends in random order.
Description: 9.3 oz (273 ml) aliquot of one of the study beverages every 15 min for a total of 28 oz (828 ml) over a 45-min period, followed by 15 min of rest. Flavored water matched for sweetness, color. flavor, but cannot be matched for saltiness.
