Regular exercise is associated with the production of small amounts of oxidative stress which might promote individual antioxidant capacity contributing to favorable training effects potentially interrelated with skeletal muscle strength. Therefore, the present study was aimed at evaluating effects of an 8-week Qigong exercise training on muscle strengths associated with responses of oxidative stress and antioxidants in young sedentary females. A total of 41 sedentary women were allocated to the Qigong exercise group (QG, N=20) or to the control group (CG, N=21). After 8 weeks of Qigong training, back and leg strength was significantly improved compared to baseline and the CG (<0.05). Plasma oxidative stress levels were reduced and total antioxidant capacity was enhanced in the QG compared to the CG (<0.05). Correlation analyses revealed that improvements in muscle strength (including both groups) were associated with changes in the levels of oxidative stress (reduction) and antioxidants (elevation). The presented findings indicate that strength training effects seem at least partly to be interrelated with alterations of the oxidant-antioxidant balance generated by the 8-week Qigong training in young sedentary females.
规律运动与少量氧化应激的产生有关，这种氧化应激可能会促进个体抗氧化能力，从而产生与骨骼肌力量潜在相关的良好训练效果。因此，本研究旨在评估为期8周的气功运动训练对久坐不动的年轻女性肌肉力量的影响，以及与氧化应激和抗氧化剂反应的关系。共有41名久坐女性被分配到气功运动组（QG，N = 20）或对照组（CG，N = 21）。经过8周的气功训练后，与基线和CG组相比，背部和腿部力量显著提高（<0.05）。与CG组相比，QG组的血浆氧化应激水平降低，总抗氧化能力增强（<0.05）。相关性分析表明，肌肉力量的改善（包括两组）与氧化应激水平的变化（降低）和抗氧化剂水平的变化（升高）有关。研究结果表明，在久坐不动的年轻女性中，8周的气功训练所产生的氧化还原平衡改变似乎至少部分地与力量训练效果相关。
