The aim of this study was to examine the effect of running exercise modality on oxidative stress. Thirteen endurance athletes (age: 21.46 ± 0.66 years) performed three different running exercise modalities (Continuous running exercise (CR): continuous running exercise at 75% of VO2max for 25 min; intermittent running exercise #1 (15/15): intermittent running protocol, 15 s running at 75% of VO2max, 15 s passive recovery, performed for 50 min; intermittent running exercise #2 (30/30): intermittent running protocol, 30 s running at 75% of VO2max, 30 s passive recovery, performed for 50 min) in a randomized order. Blood samples were drawn at rest and immediately after each running exercise and assessed for malondialdehyde (MDA), advanced oxidation protein products (AOPP), superoxide dismutase(SOD), and glutathione peroxidase (GPX) activities. MDA increased by 55% following 30/30 exercise (p < 0.01), while it remained unchanged with CR and15/15 exercise. SOD increased after CR (+13.9%, p < 0.05), and also remained unchanged after 15/15 (p > 0.05) and decreased after 30/30 (−19.7% p < 0.05). GPX and AOPP did not change after exercise in all experimental sessions (p > 0.05). In conclusion, 30/30 intermittent running induced higher lipid damages than the 15/15 and CR exercise. 15/15 intermittent exercise promoted a better balance between free radicals production and antioxidant defense compared to continuous exercise and intermittent 30/30 exercise.

不同跑步运动方式对受训运动员运动后氧化应激标志物的影响。

本研究的目的是检查跑步运动方式对氧化应激的影响。13 名耐力运动员(年龄:21.46 ± 0.66 岁)进行了三种不同的跑步锻炼方式(连续跑步锻炼 (CR):以 75% VO 2max持续跑步锻炼25 分钟;间歇性跑步锻炼 #1 (15/15):间歇性跑步锻炼跑步方案,以 VO 2max的 75% 运行 15 秒,被动恢复 15 秒,进行 50 分钟;间歇性跑步练习 #2 (30/30):间歇性跑步方案,以 VO 2max的 75% 运行 30 秒,持续 30 秒被动恢复,进行 50 分钟)以随机顺序。在休息时和每次跑步运动后立即抽取血样,并评估丙二醛(MDA)、高级氧化蛋白产物(AOPP)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPX)活性。30/30 运动后 MDA 增加 55% ( p < 0.01),而 CR 和 15/15 运动后 MDA 保持不变。CR 后 SOD 增加(+13.9%,p < 0.05),15/15 后也保持不变(p > 0.05),30/30 后下降(−19.7% p < 0.05)。在所有实验过程中,GPX 和 AOPP 在运动后均没有变化(p > 0.05)。总之,30/30 间歇跑比 15/15 和 CR 运动引起更高的脂质损伤。与持续运动和间歇性 30/30 运动相比,15/15 间歇运动促进了自由基产生和抗氧化防御之间更好的平衡。
