Moreira, A、Arsati, F、de Oliveira Lima-Arsati, YB、de Freitas, CG 和 de Araujo, VC。唾液免疫球蛋白是职业顶级五人制足球运动员的反应。 J Strength Cond Res 25(7): 1932-1936, 2011 - 本研究的目的是调查 10 名专业顶级巴西五人制足球运动员在相隔 7 天的 2 场激烈竞争的比赛后唾液免疫球蛋白 A (SIgA) 的反应。在赛前和赛后 5 分钟内收集未受刺激的唾液。 SIgA通过酶联免疫吸附测定法测量并表示为IgA的绝对浓度（SIgAabs）和IgA的分泌率（SIgArate）。使用感知运动率和心率来监测运动强度。重复测量的双向方差分析显示，SIgAab、SIgArate 和唾液流速的匹配之间没有显着差异 (p > 0.05)。然而，所有这些参数都观察到显着的时间差异。总之，我们表明，竞技训练比赛会导致顶级五人制足球运动员的 SIgA 水平下降，这表明训练刺激引起的感染的脆弱性增加。这种下降表明运动员患上呼吸道感染的风险增加，因此可能有必要采取保护措施，尽量减少与感冒病毒的接触，甚至减少运动员的训练负荷。
Moreira, A, Arsati, F, de Oliveira Lima-Arsati, YB, de Freitas, CG, and de Araujo, VC. Salivary immunoglobulin a responses in professional top-level futsal players. J Strength Cond Res 25(7): 1932-1936, 2011-The purpose of this study was to investigate the responses of salivary immunoglobulin A (SIgA) in 10 professional top-level Brazilian futsal players after 2 highly competitive games separated by 7 days. Unstimulated saliva was collected over a 5-minute period at PRE- and POST-match. The SIgA was measured by an enzyme-linked immunosorbent assay and expressed as the absolute concentration (SIgAabs) and secretion rate of IgA (SIgArate). Rate of perceived exertion and heart rate were used to monitor the exercise intensity. A 2-way analysis of variance with repeated measures showed nonsignificant differences between matches to SIgAabs, SIgArate, and saliva flow rate (p > 0.05). However, significant time differences were observed for all these parameters. In summary, we showed that a competitive training match induced a decrease in SIgA levels in top-level futsal players, which suggests an increment of the vulnerability to infections meditated by the training stimulus. This decrease suggests that the athletes were at an increased risk of developing an upper respiratory tract infection, and therefore, it could be necessary to take protective actions to minimize contact with cold viruses or even reduce the training load for athletes.
