AB  - PURPOSE: Carbohydrate (CHO) mouth rinsing (MR) prior to exercise has been shown 
      to elicit enhanced performance and energy availability in some studies. Previous 
      literature has concentrated on examining CHO MR strategies for improving aerobic 
      endurance performance in younger athletic adults. Knowledge of the impact of CHO 
      MR on functional performance in older adults is scarce. The purpose of this 
      investigation was to determine if CHO MR would improve 6-min walk test (6MWT) 
      performance, perceived exertion, and blood glucose responses in older adults. 
      METHOD: Thirty-three individuals (16 males, 17 females), age >/= 70 years performed 
      two 6MWT trials, one of which utilized a 6.4% maltodextrin CHO MR and one of 
      which utilized a placebo MR. Participants held the MR in their mouth for 20 s 
      prior to the 6MWT, and trials occurred in a counterbalanced fashion. Total 
      distance walked and rating of perceived exertion (RPE) were recorded upon 
      completion of each 6MWT. Heart rate (HR), peripheral blood oxygen saturation 
      (SpO(2)), systolic and diastolic blood pressures (BP), blood glucose, and blood 
      lactate were measured before and after each 6MWT. RESULT: CHO MR did not alter 
      the response of any study parameter compared to the placebo MR (p = 0.13-0.94). 
      HR, systolic BP, and blood lactate increased and SpO(2) decreased across time 
      (p < 0.01). CONCLUSION: A 6.4% maltodextrin CHO MR did not alter total distance 
      walked, perceived exertion, or other physiological responses elicited by the 6MWT 
      in older adults.
