Background & Purpose: there are a few studies about effects of jujube extraction and exercise status on nutrophils. The aim of present research was the acute effect of jujube solution an hour before circuit resistance exercise on human neutrophil apoptosis.
Methodology: Fourteen young male volunteer students were divided into two groups of placebo and jujube solution randomly, performing one circuit resistance exercise (9 moves/stops, 30 seconds for each exercise, 3 nonstop sets with a 3-minute active recession between sets, 10-14 repetitions, and an intensity of 75% one repeat maximum). Subjects received placebo and jujube solutions (0.5 g/kg body weight in 2.5cc of distilled water) an hour before test. Blood samples were collected 60 minutes before feeding, immediately, and 2 hours after the exercise for separation and counting the number of neutrophils, and neutrophil apoptosis was determined through AnexinV-FITC kit and flow cytometric method.
Results: Early Apoptotic Cells decreased in response to circuit resistance exercise in group of Jujube Solution feeding, and increased in Placebo group. Delayed Apoptotic Cells unchanged in response to circuit resistance exercise in group of Jujube Solution feeding but decreased in Placebo group.
Conclusion: Therefore, it might be stated that loading with edible jujube solution can be effective in inhibiting apoptosis at least for one hour before exercise. The present findings indicate that perhaps useful effects of jujube can be explained by existing glucose compounds and amino acids which could provide neutrophils with proper nutrition source in comparison with placebo.
