Abstract:
Objective To determine the ameliorative effects of Junzhi beverageⅠon neurobehavioral functions in subjects exposed to long-term sustained work.Methods Forty male students of a military institution were randomized into control group ( n=20 ) and the intervention group ( n=20 ) .All the subjects were exposed to 10-hours′high intensity mental work continuously (8∶00-18∶00).At 12∶50, the intervention group drunk a bottle of water with Junzhi beverageⅠ, but the control group drunk water of the same volume only.At 17∶00, neurobehavioral functions of all the subjects were tested by neurobehavioral core test battery (WHO-NCTB) and attention span test(AST).Results According to the results of WHO-NCBT, after 10-hours′continuous mental work,the profile of mood state in the intervention group was more stable than in the control group with lower scores in negative mood and higher scores in positive mood.Meanwhile, some of the neurobehavioral indexes were also found to be significantly improved, including shortened mean time of simple reaction and decreased error reaction rate, enhanced digit span backward, higher scores in Beton test , digit symbol test, Santa Ana practice hand and correct dot number (P<0.05).In addition, higher scores were obtained in the intervention group in AST(P<0.05).Conclusion Junzhi beverageⅠ can significantly improve the neurobehavioral function under sustained mental work conditions, which suggests that the beverage has the potential to postpone mental fatigue protect and enhance cognitive function.
