Objective: To identify the effect of spirulina supplementation on the immune cells’ indicators of young soccer players during the preparation period of a tournament. Methods: 39 undergraduate male soccer players were recruited and randomly allocated into a spirulina supplementation group (SP group, n = 20) and the placebo supplementation group (PB group, n = 19). Their elbow venous blood samples were collected before and after the preparation period of a tournament, which included 8 weeks total. The differences within the group and between groups were recorded and analyzed. Results: The ratio of the basophils in the SP group between the pre-test and post-test were statistically significantly different (p < 0.05). In the PB group, the percentage of before and after in leukocytes and monocytes were statistically significantly different (p < 0.05). In the data of the post-test, the percentage of monocytes and basophils between the SP group and PB group were statistically significantly different. The delta variations of monocytes between groups were significantly different (p < 0.05). Conclusions: Intense long-duration exercise can reduce the ratio of leukocytes and monocytes in young athletes, yet the spirulina supplement can inhibit the change. It also might improve immunity to parasites, pathogenic bacterium, and rapid-onset allergies.
观察补充螺旋藻对青年足球运动员比赛准备期免疫细胞指标的影响。方法：选择 39 名男性大学生足球运动员，随机分为螺旋藻补充组（SP 组，n=20）和安慰剂补充组（PB 组，n=19）。在 8 周的比赛准备期前后采集肘静脉血，记录并分析组内及组间差异。结果：SP 组嗜碱性粒细胞在试验前后的比值有统计学差异（p<0.05）。PB 组白细胞和单核细胞的前后百分比有统计学差异（p<0.05）。在试验后数据中，SP 组和 PB 组间单核细胞和嗜碱性粒细胞的百分比有统计学差异，组间单核细胞的差值变化有统计学差异（p<0.05）。结论：大运动量、长时间的运动可能降低青年运动员白细胞和单核细胞的比值，而螺旋藻补充可以抑制这种变化。它可能还可以提高对寄生虫、致病菌和速发性过敏的免疫力。
