OBJECTIVE
To investigate the effects of a 6-week integrated training program on the ankle joint reposition sense and postural stability in ballet dancers.
METHODS
Sixteen female ballet dancers participated in the study and underwent a 6-week integrated training program consisting of plyometric, proprioception and core stability exercises along with a home program involving additional ankle muscle strengthening and stretching. The ankle joint reposition tests and the parameters of the center of pressure (COP) while performing (deep squatting) and (standing on balls of foot) movements were measured before and after training.
RESULTS
After 6 weeks, participants showed significantly smaller absolute ankle joint reposition errors in dorsiflexion ( = 0.031), plantarflexion ( = 0.003) and eversion ( = 0.019) compared to the pre-training measurement. Furthermore, after training, a significantly slower average COP speed at pre-equilibrium during movement ( = 0.003) and pre-equilibrium phase of ( = 0.023) were observed. In addition, the maximum COP displacement in the medial-lateral direction was significantly smaller at pre-equilibrium phase during ( = 0.044) and movements ( = 0.004) after training.
CONCLUSIONS
The 6-week integrated training program improved the ankle joint reposition sense and postural control in the medial-lateral direction during and movements.
目的
探讨 6 周综合训练计划对芭蕾舞者踝关节位置觉和姿势稳定性的影响。
方法
16 名女性芭蕾舞者参与了本研究，接受了 6 周的综合训练计划，包括增强式训练、本体感受和核心稳定性练习，以及包括额外的踝关节肌肉强化和伸展的家庭训练计划。在训练前后，对踝关节位置觉测试和进行（深蹲）和（足尖站立）动作时的压力中心（COP）参数进行了测量。
结果
6 周后，与训练前相比，参与者在背屈（=0.031）、跖屈（=0.003）和外展（=0.019）时的踝关节位置觉绝对误差明显减小。此外，在训练后，在（深蹲）运动的预平衡期间，COP 速度的平均变化明显减慢（=0.003），（足尖站立）的预平衡阶段也明显减慢（=0.023）。此外，在（深蹲）和（足尖站立）运动的预平衡阶段，COP 在横向的最大位移明显减小（=0.044）和（=0.004）。
结论
6 周的综合训练计划提高了芭蕾舞者在（深蹲）和（足尖站立）运动中横向的踝关节位置觉和姿势控制能力。
