Abstract

The objective of this study was to clarify whether there are sex-specific differences in salivary α-amylase and immunoglobulin A responses following acute endurance exercise in adolescent males and females with equivalent cardiorespiratory fitness levels. Twenty-six aerobically trained adolescent males and females with similar training status were enrolled in this study. Each individual executed a 1-h prolonged cycling exercise corresponding to a constant power output at 65% of peak oxygen uptake. Unstimulated whole salivary samples were taken with the passive drooling method at the 10-min period before and after exercise for the determination of salivary responses [α-amylase, immunoglobulin A, total protein and flow rate]. Salivary α-amylase activity, immunoglobulin A concentration and total protein concentration were significantly augmented immediately after acute endurance exercise. Regarding sex differences, only the salivary flow rate was significantly lower in females than in males. The findings of the present study imply that adolescent males and females appear to have similar salivary responses after acute endurance exercise, as represented by salivary α-amylase activity and immunoglobulin A concentration in connection with total protein concentration and salivary flow rate, when they are matched for peak oxygen uptake relative to fat-free body mass.

评估耐力运动后唾液α-淀粉酶和免疫球蛋白A对有氧运动能力相似的青少年男性和女性的反应。
本研究的目的是要弄清心肺功能水平相当的青少年男性和女性在急性耐力运动后唾液α-淀粉酶和免疫球蛋白A的反应是否存在性别差异。本研究选取了 26 名接受过有氧运动训练且训练状况相似的青少年男性和女性作为研究对象。每个人都进行了 1 小时的长时间自行车运动,以 65% 的峰值摄氧量进行恒定功率输出。在运动前和运动后 10 分钟,采用被动流口水法采集未受刺激的全唾液样本,以测定唾液反应[α-淀粉酶、免疫球蛋白 A、总蛋白和流速]。急性耐力运动后,唾液中的α-淀粉酶活性、免疫球蛋白A浓度和总蛋白浓度立即显著增加。在性别差异方面,只有女性的唾液流速明显低于男性。本研究的结果表明,青少年男性和女性在急性耐力运动后似乎有相似的唾液反应,表现为唾液α-淀粉酶活性和免疫球蛋白A浓度与总蛋白浓度和唾液流速的关系,当他们的峰值摄氧量与去脂体重相匹配时,唾液α-淀粉酶活性和免疫球蛋白A浓度与总蛋白浓度和唾液流速的关系也相似。

期刊介绍: The European Journal of Oral Sciences is an international journal which publishes original research papers within clinical dentistry, on all basic science aspects of structure, chemistry, developmental biology, physiology and pathology of relevant tissues, as well as on microbiology, biomaterials and the behavioural sciences as they relate to dentistry. In general, analytical studies are preferred to descriptive ones. Reviews, Short Communications and Letters to the Editor will also be considered for publication. The journal is published bimonthly.
