绿色小球藻含有高水平的蛋白质、维生素和矿物质。我们以前报道过，一种来源于阿霉的多组分补充剂增加了人类唾液分泌型免疫球蛋白A（SIgA）的分泌速率。在这里，我们调查是否摄入这种灵芝衍生的补充剂减弱唾液SIgA分泌率降低在剑道训练营。10名女剑道运动员参加了大学间为期6天的春季和为期4天的夏令营。他们被随机分为两组;一组在春季夏令营期间服用安慰剂片剂，另一组在夏季夏令营期间服用安慰剂片剂，另一组在春季夏令营期间服用安慰剂片剂。受试者在营地前4周开始服用这些片剂，直到营地后唾液采样。唾液SIgA浓度通过ELISA测量。所有受试者几乎都参加了所有的训练项目，两组在训练营期间的体重变化和主观身体健康评分是相当的。但唾液SIgA分泌率的变化在各组之间存在差异。安慰剂组的唾液SIgA分泌率在夏令营期间下降（前与第二，中间，最后一天的营地，营地后：146 ± 89 vs. 87 ± 56、70 ± 45、94 ± 58和116 ± 71 μg/min），而在大肠杆菌组中未观察到此类降低（121 ± 53与113 ± 68、98 ± 69、115 ± 80和128 ± 59 μg/min）。我们的研究结果表明，使用一种来源于海蛞蝓的膳食补充剂减弱了唾液SIgA分泌减少在训练营的竞争性运动。
The green alga Chlorella contains high levels of proteins, vitamins, and minerals. We previously reported that a chlorella-derived multicomponent supplement increased the secretion rate of salivary secretory immunoglobulin A (SIgA) in humans. Here, we investigated whether intake of this chlorella-derived supplement attenuated the reduced salivary SIgA secretion rate during a kendo training camp. Ten female kendo athletes participated in inter-university 6-day spring and 4-day summer camps. They were randomized into two groups; one took placebo tablets during the spring camp and chlorella tablets during the summer camp, while the other took chlorella tablets during the spring camp and placebo tablets during the summer camp. Subjects took these tablets starting 4 weeks before the camp until post-camp saliva sampling. Salivary SIgA concentrations were measured by ELISA. All subjects participated in nearly all training programs, and body-mass changes and subjective physical well-being scores during the camps were comparable between the groups. However, salivary SIgA secretion rate changes were different between these groups. Salivary SIgA secretion rates decreased during the camp in the placebo group (before vs. second, middle, and final day of camp, and after the camp: 146 ± 89 vs. 87 ± 56, 70 ± 45, 94 ± 58, and 116 ± 71 μg/min), whereas no such decreases were observed in the chlorella group (121 ± 53 vs. 113 ± 68, 98 ± 69,115 ± 80, and 128 ± 59 μg/min). Our results suggest that a use of a chlorella-derived dietary supplement attenuates reduced salivary SIgA secretion during a training camp for a competitive sport.
