The study aimed to determine the suitability of testing the saliva of kickboxing athletes to show changes in biochemical parameters in dynamic of training. 8 elite male athletes (mean age 17.29± 0.31 years, body mass 66.82± 3.46kg, with 5.62±0.96 years of training experience) participated in the study. Indicators of lipid peroxidation and glycolysis (the concentration of lactic acid and pyruvic acid) were defined before and after a training session. Significant increases in indicators of lipid peroxidation activity indicators and the concentration of lactic acid (4-fold) were observed; analysis of correlation matrices confirms the absence of expressed changes. At the same time, significant decreases in catalase (10-fold from 3.69 kat/L to 0.39 kat/L) and pyruvic acid (from 3.92 l/l to 0.55 l/l) were observed. Our results confirm the value of using saliva to determine training load in an individual. Moreover, the study provided information on the importance of indexes reflecting a correlation of various biochemical indicators to estimate the sufficiency of training loads. The ease of sampling and informational content of saliva are reasons to use such tests in monitoring athletes' functional state to prevent fatigue.
本研究旨在确定检测跆拳道运动员唾液以显示训练动态中生化参数变化的适用性。8 名男性精英运动员（平均年龄 17.29±0.31 岁，体重 66.82±3.46kg，训练经验 5.62±0.96 年）参加了这项研究。在训练前后定义了脂质过氧化和糖酵解（乳酸和丙酮酸浓度）的指标。观察到脂质过氧化活性指标和乳酸浓度显著增加（增加 4 倍）；相关矩阵分析证实没有明显变化。同时，过氧化氢酶（从 3.69 kat/L 降低到 0.39 kat/L，降低 10 倍）和丙酮酸（从 3.92 l/l 降低到 0.55 l/l）显著降低。我们的结果证实了使用唾液来确定个体训练负荷的价值。此外，该研究提供了有关反映各种生化指标相关性的指标对于估计训练负荷充足性的重要性的信息。唾液采样方便且信息量丰富，这是在监测运动员功能状态以预防疲劳时使用此类测试的原因。
