【摘要】：目的:研究补充维生素D对于游泳运动员上呼吸道感染发病次数的影响并探讨其免疫学机制。方法:研究对象:16名专业游泳运动员,随机分为两组:维生素D胶囊补充组和空白对照组,每组8人。在饮食和作息时间基本一致的情况下,补充组口服维生素D胶囊,对照组不补充,观察两组运动员生理机能的变化情况。结果:1)两组在实验前血清中25-(OH)D3含量都低于健康标准,补充组口服维生素D胶囊3个月后血清中25-(OH)D3升至正常值,对照组仍偏低;2)补充组外周血淋巴细胞Th/Ts比值和NK细胞数高于对照组,有显著性差异(P0.05);3)补充组外周血IgA水平高于对照组,有显著性差异(P0.05);4)补充组冬训期间感冒次数显著少于对照组,有显著性差异(P0.05)。结论:补充维生素D对于降低冬训期间游泳运动员上呼吸道感染发病次数有良好的效果,在正常范围内提高Th/Ts比值,NK细胞数以及IgA水平可能是其作用机理,有待进一步的实验证明。
[Abstract]:Objective: to study the effect of vitamin D supplementation on the incidence of upper respiratory tract infection in swimmers and its immunological mechanism. Methods: one hundred and sixteen professional swimmers were randomly divided into two groups: vitamin D capsule supplement group and blank control group. Under the condition that the diet and the rest time were basically the same, the supplement group took vitamin D capsule orally, while the control group did not. The changes of physiological function of the two groups were observed. Results (1) the serum 25-(OH)D3 content in both groups was lower than the healthy standard before the experiment. The serum 25-(OH)D3 level in the supplement group rose to normal after taking vitamin D capsule for 3 months. The ratio of Th/Ts and NK cells in peripheral blood lymphocytes in the supplement group was higher than that in the control group, and there was a significant difference between the two groups (P < 0.05). The level of IgA in the peripheral blood of the supplement group was higher than that of the control group. The number of colds in the supplementation group was significantly lower than that in the control group (P 0.05). Conclusion: vitamin D supplementation has a good effect on reducing the incidence of upper respiratory tract infection in swimmers during winter training. Increasing the number of Th/Ts / NK cells and the level of IgA may be the mechanism of vitamin D supplementation in normal range. Further experiments are needed.
