This work aims to assess footprint parameters in a group of professional ballet dancers and to determine the correlation between the aforementioned parameters and lateralization, stabilometric parameters, pedobarographic parameters and work environment conditions. A group subjected to tests consisted of 44 elite professional ballet dancers and the reference group was composed of 44 students. The test of balance and thrust under feet involved 30 s-long free standing with open eyes on a podographic platform. The research-related analysis was concerned with footprint parameters (foot length and width, Clarke angle, and Weissflog index), stabilometric parameters (path length and ellipse field, mean value of the velocity and deflection of the displacement of the center of the foot pressure on the ground) and pedobarographic parameters (percentage thrust on the right, left foot as well as the front and rear part the foot). Statistically significant differences between the groups were observed in relation to the stabilometric parameters, the percentage pressure of the left forefoot and the right heel, as well as the value of the Clarke angle ( ≤ 0.05). The longitudinal arch of the foot and the width of the foot in ballet dancers are not dependent on the total and professional career duration and weekly training volume.
这项研究旨在评估一组专业芭蕾舞演员的足底参数，并确定上述参数与偏侧化、稳定测量参数、足压测量参数以及工作环境条件之间的相关性。接受测试的一组包括44名精英专业芭蕾舞演员，参考组由44名学生组成。足部平衡和推力测试包括在足印平台上睁眼自由站立30秒。与研究相关的分析涉及足底参数（足长和足宽、克拉克角和魏斯弗洛格指数）、稳定测量参数（路径长度和椭圆场、足底压力中心位移速度和偏斜度的平均值）以及足压测量参数（右脚、左脚以及足部前后部分的推力百分比）。两组之间在稳定测量参数、左前足和右足跟的压力百分比以及克拉克角值方面观察到统计学上的显著差异（≤0.05）。芭蕾舞演员的足纵弓和足宽不取决于总的职业生涯时长和每周训练量。
