走扁带代表了一种现代体育活动，人们必须在拉紧的丝带上保持平衡。第一次在松绳上的试验导致支撑腿无法控制的横向摆动。训练可以减少这些振荡，从而改善姿势控制。然而，潜在的神经机制尚不清楚。因此，本研究旨在强调与走扁带训练相伴的脊柱适应。 24 名受试者被分配到训练组或对照组，并在 10 次训练之前和之后评估姿势控制。此外，还引出了比目鱼肌霍夫曼 (H) 反射来评估脊髓反射回路兴奋性的变化。受过训练的受试者能够在松弛线上保持平衡至少 20 秒（P
Slacklining represents a modern sports activity where people have to keep balance on a tightened ribbon. The first trials on the slackline result in uncontrollable lateral swing of the supporting leg. Training decreases those oscillations and therefore improves postural control. However, the underlying neural mechanisms are not known. Therefore, the present study aimed to highlight spinal adaptations going along with slackline training. Twenty-four subjects were either assigned to a training or a control group and postural control was assessed before and after the 10 training sessions. Additionally, soleus Hoffmann (H)-reflexes were elicited to evaluate changes in the excitability of the spinal reflex circuitry. Trained subjects were able to maintain balance on the slackline for at least 20 s (P
