乳酸阈值（LT 1），其定义为在递增运动期间乳酸浓度的首次升高，尚未在临床环境中无创和方便地确定。我们的目的是使用我们的可穿戴乳酸传感器在运动过程中观察汗液中乳酸浓度的变化，并研究乳酸阈值（LT 1）和排泄阈值（VT 1）之间的关系。23例健康受试者和42例心血管疾病患者在运动过程中，汗液乳酸值的动态变化是实时可视化的，运动后汗液乳酸值持续急剧上升，直至意志衰竭，恢复期逐渐下降。汗液中的LT 1与血液中的LT 1和VT 1具有良好的相关性（r分别为0.92和0.71）。此外，Bland-Altman图描述了平均值之间无偏倚（平均差异分别为-4.5和2.5 W）。在运动期间连续监测乳酸浓度可以为检测VT 1提供额外的信息。
The lactate threshold (LT1), which is defined as the first rise in lactate concentration during incremental exercise, has not been non-invasively and conveniently determined in a clinical setting. We aimed to visualize changes in lactate concentration in sweat during exercise using our wearable lactate sensor and investigate the relationship between the lactate threshold (LT1) and ventilatory threshold (VT1). Twenty-three healthy subjects and 42 patients with cardiovascular diseases (CVDs) were enrolled. During exercise, the dynamic changes in lactate values in sweat were visualized in real-time with a sharp continuous increase up to volitional exhaustion and a gradual decrease during the recovery period. The LT1 in sweat was well correlated with the LT1 in blood and the VT1 (r = 0.92 and 0.71, respectively). In addition, the Bland–Altman plot described no bias between the mean values (mean differences: − 4.5 and 2.5 W, respectively). Continuous monitoring of lactate concentrations during exercise can provide additional information for detecting the VT1.
