本研究的目的是比较急性抗阻运动前后血液和唾液中的氧化应激生物标志物。1次最大重复（1RM）测试后1周，11只健康的训练有素的雄鼠完成了一次增厚急性阻力训练，包括3组10组，每次重复75%的1RM，每组之间有90次休息时间。在抗阻训练前（前）和后（后）10分钟采集静脉血和唾液样本。与基线值相比，急性阻力训练后血乳酸积累显著（p < 0.05）升高（前：1.6 +/- 0.4 vs后：9.5 +/- 2.4）。急性阻力训练后TBARS（42%）、AOPP（28%）、尿酸（27%）和GSH（14%）较训练前显著升高（p < 0.05）。急性抗阻训练后唾液中尿酸水平显著升高（p < 0.05）（36%），血尿酸与唾液尿酸水平显著相关（p < 0.05）。统计分析未显示唾液氧化应激生物标志物的任何其他变化。综上所述，急性抗阻运动在急性抗阻训练后的血浆中诱导氧化应激，而在唾液样本中除尿酸外未发现氧化应激。
The aim of the present study was to compare oxidative stress biomarkers determined in blood and saliva before and after acute resistance exercise. 1 week after 1 maximum repetition (1RM) test 11 healthy well-trained males completed a hypertrophy acute session of resistance training including 3 sets of 10 repetitions at 75% of the 1RM, with 90s rest periods between sets. Venous blood and saliva samples were collected before (pre) and 10 min after (post) the resistance training session. A significant (p < 0.05) rise in blood lactate accumulation (pre: 1.6 +/- 0.4 vs. post: 9.5 +/- 2.4) was found post-acute resistance training compared with baseline values. Significant increases (p < 0.05) in TBARS (42%), AOPP (28%), uric acid (27%) and GSH (14%) were detected post-acute resistance training in relation to pre in blood samples. A significant increase (p < 0.05) in uric acid (36%) was found in saliva post-acute resistance training as well as a significant correlation (p < 0.05) between uric acid determined in blood and saliva. Statistical analysis did not reveal any other change in the salivary oxidative stress biomarkers. In conclusion, an acute session of resistance exercise induces oxidative stress in plasma of trained men after acute resistance training, which was not found in saliva samples except for uric acid.
