Saliva provides a convenient and noninvasive matrix for assessing specific physiological parameters, including some biomarkers of exercise. We investigated whether the total protein concentration of whole saliva (TPWS) would reflect the anaerobic threshold during an incremental exercise test. After a warm-up period, 13 nonsmoking men performed a maximum incremental exercise on a cycle ergometer. Blood and stimulated saliva were collected during the test. The TPWS anaerobic threshold (PAT) was determined using the Dmax method. The PAT was correlated with the blood lactate anaerobic threshold (AT; r = .93, p < .05). No significant difference (p = .16) was observed between PAT and AT. Thus, TPWS provides a convenient and noninvasive matrix for determining the anaerobic threshold during incremental exercise tests.
唾液为评估特定生理参数提供了一种方便且无创的基质,其中包括一些运动的生物标志物。我们研究了全唾液总蛋白浓度(TPWS)是否可以反映递增运动试验中的无氧阈。在热身阶段后,13 名不吸烟的男性在自行车测力计上进行了最大递增运动。在测试过程中采集血液和刺激唾液。使用 Dmax 方法确定 TPWS 的无氧阈(PAT)。PAT 与血液乳酸无氧阈(AT)相关(r =.93,p <.05)。PAT 与 AT 之间无显著差异(p =.16)。因此,TPWS 为递增运动试验中确定无氧阈提供了一种方便且无创的基质。
