In the case of Hungarian folk dancers, it is crucial to maintain correct posture and promptly respond to imbalances. However, traditional dances often lack specific training to develop these skills.
In this present study, twelve dancers (8 male, 4 female, age: 21.7 ± 3.6 years) and ten non-dancers subjects forming a control group (6 male, 4 female, age: 21.6 ± 2.87 years) participated. During the measurements a 60-second long bipedal balancing test on the balance board was completed two times, and a spinning intervention was inserted in between the two sessions. The balance capabilities of the two groups were assessed through the characterization of motion on an unstable board, and the analysis of subject's center of mass and head movements.
Dancers applied a more sophisticated and resource-intensive strategy to address the balancing task, yielding a better balancing performance in terms of balance board parameters. By preferring a solid stability in the medio-lateral direction, a greater fluctuation in the anterior-posterior direction can be observed (e.g., significantly lower SampEn values). The overall more successful performance is further evidenced by within-subject comparison since significant differences were observed mostly within the control group. Based on the results, the advanced balancing ability of the folk dancer group is more likely to be acquired through years of experience.
The results indicate that additional specialized training could further enhance this ability, encouraging the reliance on poorly memorized corrective movements and reducing the risk of injury.
对于匈牙利民间舞者而言，保持正确姿势并迅速应对失衡状况至关重要。然而，传统舞蹈往往缺乏培养这些技能的特定训练。
在本研究中，12名舞者（8名男性，4名女性，年龄：21.7±3.6岁）和10名非舞者组成对照组（6名男性，4名女性，年龄：21.6±2.87岁）参与其中。在测量过程中，在平衡板上进行了两次时长60秒的双足平衡测试，两次测试之间插入了一次旋转干预。通过对不稳定板上的运动特征进行表征以及对受试者的质心和头部运动进行分析，评估两组的平衡能力。
舞者采用了更为复杂且资源密集型的策略来完成平衡任务，就平衡板参数而言，其平衡表现更佳。由于更倾向于在内外侧方向保持稳固的稳定性，因此可以观察到前后方向有更大的波动（例如，样本熵值显著更低）。受试者内部比较进一步证明了整体表现更为成功，因为大多显著差异是在对照组内部观察到的。基于这些结果，民间舞者组先进的平衡能力更有可能是通过多年经验获得的。
结果表明，额外的专业训练可以进一步提升这种能力，鼓励依靠记忆不佳的纠正动作，并降低受伤风险。
