DataSheet_1_The effect of yin yoga intervention on state and trait anxiety during the COVID-19 pandemic.docx

IntroductionAlthough some findings indicate that yoga can reduce stress and anxiety, many studies present mixed results. The potential of yoga interventions to alleviate anxiety, including the mechanisms and boundary conditions by which it does so, is an under-researched topic. Anxiety is often divided into “state anxiety” and “trait anxiety,” the former being a temporary reaction to stressful events, while the latter is a more stable personality feature that responds to adverse situations or perceived threats.
Materials and methodsThis study investigates whether a yin yoga intervention delivered online reduces state anxiety immediately after each yoga session and whether the anxiety levels are significantly lower at the end of the 10-week yoga intervention than at the beginning of the study. We also predicted no effect of yin yoga intervention on trait anxiety. The study was conducted during the COVID-19 pandemic when participants (N = 48 Latvian women) experienced heightened anxiety levels.
ResultsThis study shows that a ten-week online yin yoga intervention significantly reduced state anxiety in the intervention group compared with the control group. State anxiety levels also significantly decreased after each yin yoga session, providing more support for the anxiety-reducing effect of yin yoga. In contrast, yoga participation did not cause differences in trait anxiety between the control and intervention groups, even though trait anxiety decreased in the intervention group and increased in the control group over the study period.
ConclusionThe positive effects of yin yoga on state anxiety indicate the potential of yin yoga intervention as a first-line treatment to control and reduce state anxiety, with possible additional effects on trait anxiety.

引言
尽管已有研究表明瑜伽可缓解应激与焦虑，但诸多相关研究的结果并不一致。瑜伽干预在缓解焦虑方面的潜力——包括其作用机制与边界条件——仍是研究尚不充分的议题。焦虑通常可分为状态焦虑（State Anxiety）与特质焦虑（Trait Anxiety）：前者是个体对应激事件产生的暂时性反应，后者则是个体面对逆境或感知到威胁时表现出的更为稳定的人格特质。

材料与方法
本研究旨在探究：线上开展的阴瑜伽（Yin Yoga）干预是否可在单次练习结束后即刻降低状态焦虑，以及为期10周的干预结束时，受试者的焦虑水平是否显著低于研究初始阶段。本研究同时预设：阴瑜伽干预对特质焦虑无显著影响。本次研究在新型冠状病毒肺炎（COVID-19）疫情期间开展，彼时受试群体（N=48名拉脱维亚女性）的焦虑水平普遍升高。

结果
本研究结果显示：与对照组相比，为期10周的线上阴瑜伽干预可显著降低干预组受试者的状态焦虑水平；且单次阴瑜伽练习结束后，受试者的状态焦虑水平亦出现显著下降，进一步佐证了阴瑜伽的抗焦虑效应。与之形成对照的是，尽管研究周期内干预组的特质焦虑水平有所降低，而对照组的特质焦虑水平呈上升趋势，但参与阴瑜伽并未使两组受试者的特质焦虑水平出现显著差异。

结论
阴瑜伽对状态焦虑的积极效应表明，阴瑜伽干预有望成为管控与缓解状态焦虑的一线干预手段，同时或可对特质焦虑产生额外调控作用。
