Comparison of a Sucrose-Based and Rice-Based Sports Beverage on Hydration Status During a 19.3-km Foot March in ROTC Cadets

Heileson, JL, Peterson, M, Adair, KE, and Funderburk, LK. Comparison of a sucrose-based and rice-based sports beverage on hydration status during a 19.3-km foot march in ROTC cadets. J Strength Cond Res 36(4): 1105–1110, 2022—The purpose of this field study was to determine whether a rice-based sport beverage (RB) maintains hydration status compared to a sucrose-based sports beverage (SB) during a load-bearing 19.3-km foot march. Eighteen Reserve Officer Training Corps (ROTC) cadets (male, n = 11; female, n = 7) were randomly assigned to consume either 2.84 L of an RB (carbohydrate, 114 g; sodium, 1306 mg) or SB (carbohydrate, 170 g; sodium, 1136 mg) throughout the duration of the foot march (temperature 14.44° C, humidity 50%). The sports beverages were distributed once before the event and then every 3.2 km for a total of 6 servings (0.47 L each). Pre- and post-urine specific gravity (USG) and body mass were used to assess hydration status. A survey was used to determine subjective ratings of perceived exertion and gastrointestinal (GI) discomfort. The level of significance was set at p
