Numerous research studies have investigated the relationship between exercise, oxidative stress level, and condition in athletes who engage in intense training on a daily basis. However, it is known that oxidative stress is affected by exercise, sleep, and the psychological state, but there are only a few studies that have comprehensively examined oxidative stress based on the actual practice periods and living conditions of athletes. Therefore, our study aimed to explore the influence of three distinct training periods (short training period, intensive training period, and pre-competition periods) as well as life situations (sleep and number of steps) on oxidative stress levels (diacron reactive oxygen metabolites: d-ROMs) in high school judo athletes. The results showed that, among the three periods, the level of oxidative stress increased the most during the pre-competition period, and the value was higher than during the training period, when the intensity of training was highest. The levels of the d-ROMs values during the pre-competition period were negatively correlated with the amount of sleep on the previous day. The findings suggest that, besides the exercise intensity, factors such as sleep duration and other life situations should be regarded as critical considerations for high school judo athletes.
众多研究调查了日常进行高强度训练的运动员的运动、氧化应激水平和身体状况之间的关系。然而，众所周知，氧化应激会受到运动、睡眠和心理状态的影响，但仅有少数研究基于运动员的实际训练周期和生活状况对氧化应激进行了全面考察。因此，我们的研究旨在探究三个不同训练阶段（短期训练阶段、强化训练阶段和赛前阶段）以及生活状况（睡眠和步数）对高中柔道运动员氧化应激水平（戴克隆活性氧代谢物：d-ROMs）的影响。结果显示，在这三个阶段中，氧化应激水平在赛前阶段升高得最多，且该数值高于训练强度最高的训练阶段。赛前阶段的d-ROMs值与前一天的睡眠时长呈负相关。研究结果表明，除了运动强度外，睡眠时间等因素以及其他生活状况对于高中柔道运动员而言应被视为关键考量因素。
