Article in press:

The present study investigated the acute and short-term effects of oral feeding of jujube solution on white blood cell (WBC) and its differential count in response to circuit resistance exercise. Fourteen young male volunteer students were randomly divided into the placebo and jujube solution groups. All participants performed one circuit resistance exercise [9 stations/nonstop, 30 seconds for each station (10-14 repetitions), 3 sets with a 3-minute active rest between sets, and an intensity of 75% with one repeat maximum]. In an acute supplementation protocol, participants received either a placebo or a jujube solution (0.5 g/kgbody weight in 2.5cc of distilled water) an hour before testing. Blood samples were collected 60 minutes before feeding, immediately after, and 2 hours after the exercise. In the short-term supplementation protocol, participants received either placebos or jujube solutions (0.5 g/kgbody weight in 2.5cc of distilled water) for as long as 7 days at certain times and in a double-blind manner. Blood samples were collected 30 minutes before, immediately after, and 2 hours after the exercise. WBC, lymphocytes (LYM), and neutrophils (NEUT) were measured with a hematology auto analyzer. The WBC, LYM, and NEUT were not affected by both acute and short-term supplementation type; but WBC and NEUT was increased during exercise and also recovery period. However, NEUT:LYM ratio were not affected by acute supplementation type; but in short-term supplementation, when it increased in the placebo group during the recovery period, its alterations were insignificant in the jujube solution group (p=0.045). In conclusion, jujube solution loading during one week probably could inhibit acute stress resulted from relatively intense circuit resistance exercise and probably could protect from inflammation and open window phenomenon resulted from exercise.
