Exercise has been shown to increase the production of reactive oxygen species (ROS) to a point that can exceed antioxidant defenses, to cause oxidative stress. The aim of our trials was to evaluate oxidative stress and recovery times in trained dogs during two different hunting exercises, with reactive oxygen metabolites-derivatives (d-ROMs) and biological antioxidant potential (BAP) tests. A group of nine privately owned Italian hounds were included. A 20-min aerobic exercise and a 4-h aerobic exercise, after 30 days of rest, were performed by the dogs. Our results show an oxidative stress after exercise due to both the high concentration of oxidants (d-ROMs) and the low level of antioxidant power (BAP). Besides, the recovery time is faster after the 4-h aerobic exercise than the 20-min aerobic exercise. Oxidative stress monitoring during dogs exercise could become an interesting aid to establish ideal adaptation to training.
运动已被证明会增加活性氧（ROS）的产生，达到超过抗氧化防御的程度，从而导致氧化应激。我们的试验目的是评估在两种不同的狩猎运动中，经过训练的狗的氧化应激和恢复时间，使用活性氧代谢物衍生物（d-ROMs）和生物抗氧化潜能（BAP）测试。我们纳入了一组 9 只私人拥有的意大利猎犬。这些狗在休息 30 天后，分别进行了 20 分钟的有氧运动和 4 小时的有氧运动。我们的结果显示，由于氧化剂（d-ROMs）浓度高和抗氧化能力（BAP）低，运动后会产生氧化应激。此外，4 小时有氧运动后的恢复时间比 20 分钟有氧运动后的恢复时间更快。在狗运动期间监测氧化应激可能成为确定对训练的理想适应的一个有趣辅助手段。
