本研究的目的是评估日常节奏的过氧化参数在未经训练和训练的马。每4 h采集一次血样，持续48 h，用于测定活性氧代谢物试验（d-ROM）、抗氧化屏障（Oxy-ads）、巯基抗氧化屏障（SHp）和脂质过氧化（LPO）。双因素方差分析显示，除LPO外，一天中的时间对研究的所有参数均有显著影响。在监测的两天期间，在训练的马中观察到较高的Oxy-ads和SHp值（p < 0.01）。所有研究的参数，除了LPO，表现出强大的每日节律。他们的acro-phase发生在白天在未经训练的马和晚上在训练的马。我们的研究结果表明，训练增加抗氧化能力，并证明，每日节奏的抗氧化参数可以修改的训练。
The aim of this study was to evaluate the daily rhythms of peroxidative parameters in untrained and trained horses. Blood samples were collected every 4 h for a 48-h period for the determination of reactive oxygen metabolites test (d-ROMs), antioxidant barrier (Oxy-ads), thiol antioxidant barrier (SHp) and lipid peroxidation (LPO). Two-way ANOVA showed a significant effect of time of day on all parameters studied, except on LPO. Higher values of Oxy-ads and SHp were observed in trained horses during both days of monitoring (p < 0.01). All studied parameters, except for LPO, showed robust daily rhythms. Their acro-phases occurred during the day in untrained horses and in the evening in trained horses. Our results showed that training increases antioxidative capacity and demonstrated that the daily rhythms of antioxidative parameters can be modified by training.
