Abstract：
Ego-depletion describes a state of mind, where the capacity for self-control is temporarily depleted after a primary self-control action. The aim of this study was to investigate whether a brief virtual reality-based mindfulness breathing meditation with integrated biofeedback can be considered an effective strategy to counteract the detrimental effects of ego depletion on motor skill performance under pressure. The study included two experiments, each of them designed as counterbalanced cross-over trials and based on an a priori sample-size calculation. Within each experiment, participants completed two appointments in a randomly assigned order, during which they were asked to perform 20 basketball free throws (N = 18; Experiment 1) or 20 penalty kicks at a football goal in four target squares (N = 16; Experiment 2) under pressure pre and post the following conditions: Stroop-test-induced ego depletion followed by a 15 min resting break, Stroop-test-induced ego depletion followed by a 15 min virtual reality-based mindfulness breathing meditation with integrated biofeedback. Results indicate that, in comparison to a resting break, a brief virtual reality-based mindfulness meditation with integrated biofeedback can counteract the detrimental effects of ego-depletion (Experiment 2) and enhance motor skill performance under pressure (Experiment 1, 2) Implications for researchers and practitioners are derived in light of the identified methodological limitations.
摘要：
自我消耗描述了一种精神状态，在主要的自我控制行动后，自我控制能力暂时耗尽。这项研究的目的是调查具有集成生物反馈的简短的基于虚拟现实的正念呼吸冥想是否可以被认为是一种有效的策略，以抵消自我消耗对压力下运动技能表现的不利影响。这项研究包括两个实验，他们每个人都设计为平衡交叉试验，并基于先验样本量计算。在每个实验中，参与者以随机分配的顺序完成了两个约会，在此期间，他们被要求在以下条件前后的压力下在四个目标方块（N=16；实验2）中对足球进球进行20次篮球罚球（N=18；实验1）或20次罚球：Stroop测试引起的自我消耗，然后休息15分钟，Stroop测试引起的自我消耗，然后进行15分钟的基于虚拟现实的正念呼吸冥想和综合生物反馈。结果表明,与休息休息相比，一个简短的基于虚拟现实的正念冥想和综合生物反馈可以抵消自我消耗的有害影响(实验2)，并提高压力下的运动技能表现(实验1,2)根据已确定的方法局限性得出对研究人员和从业者的启示。
