TI  - Effect of carbohydrate administration on recovery from stress-induced deficits in 
      cognitive function: a double-blind, placebo-controlled study of soldiers exposed 
      to survival school stress.
PG  - 132-8
AB  - OBJECTIVE: The goal of this project was to evaluate the effects of energy 
      supplementation, as liquid carbohydrate (CHO), on facilitating recovery of 
      cognitive function in soldiers who have been exposed to sustained psychological 
      and physical stress during Survival School Training. PROJECT DESIGN: A 
      double-blind, placebo-controlled design was used. Healthy, male volunteers 
      attending survival training were recruited for participation in the study. At the 
      conclusion of the mock captivity phase of survival training and before a recovery 
      night of sleep, subjects participated in cognitive testing. After this, subjects 
      were randomly assigned to one of three treatment groups. Subjects received either 
      a 6% CHO (35.1 kJ/kg), 12% CHO (70.2 kJ/kg), or placebo beverage in four 
      isovolemic doses. In the morning of the following day, all subjects participated 
      in a second assessment of cognitive functioning. RESULTS: Compared to subjects 
      who received placebo, those who received supplemental CHO beverages exhibited 
      significantly improved performance on a complex cognitive task (i.e., Stroop 
      Test) involving concentration effectiveness associated with selective attention 
      and response inhibition. No differences were observed on a variety of cognitive 
      tasks of lesser complexity. DISCUSSION: These data suggest nutritional 
      interventions enhance the rapid recovery of complex cognitive functions impaired 
      by exposure to significant or sustained stressful conditions. In addition to 
      enhancing speed of recovery of function between operational intervals, the 
      current data suggest that dietary supplement strategies may hold promise for 
      enhancing field performance and a capacity to assist in sustaining operations by 
      military personnel over time.
