- Abstract
This study aims to discuss the effect and the protection mechanism of lycium barbarum polysaccharide (LBP) supplement after highly intense training on immunity of athletes. We selected 18 experiment athletes from colleges and divided them into the control group (A), pure training group (B) and LBP supplement group (C). Athletes in group B and C went through highly intense training everyday. The athletes in group C took LBP capsules (5 g each day) morning and night everyday, while the athletes in group B took placebos (5 g) morning and night everyday. Athletes in group A did not need any training but took placebos (5 g) morning and night everyday. Tlymphocyte subsets, immune globulin and interleukin-2 (IL-2) activities of athletes were detected before and after the experiment for further analysis. In the meantime, in order to detect the effect of LBP on immune organs damage caused by highly intense training, we took mice as the research objects and divided them into three groups (group D, E and F) in the same way, thus to detect the spleen and thymus indexes of mice for results analysis. Results showed that, after highly intense training, compared with group A, the specific values of CD4+%, CD4+ and CD8+ of athletes in group B declined remarkably (p < 0.01); the specific value of CD8+% also decreased but only slightly (p > 0.05). The specific values of CD4+%, CD8+%, CD4+ and CD8+ of athletes in group C increased significantly compared with group A; moreover, compared with group A and B, detected data of immunoglobulin A (IgA), immunoglobulin M (IgM) and immunoglobulin G (IgG) of group C increased remarkably (p < 0.05). Compared with group A and B, activities of IL-2 of athletes in group C enhanced substantially. The thymus indexes of mice in group E were lower than that of the other two groups (p < 0.05); no significant difference was discovered in spleen and thymus indexes between group F and group D (p > 0.05). In conclusion, supplement of LBP can effectively prevent the decrease of immunity of athletes after highly intense training, as well as has significant inhibiting effect on the immune organs damage caused by highly intense training.
