Abstract

The purpose of this study was to compare kinetic differences of static balance between female dancers (D) with at least seven years of dance experience and female non-dancers (ND) who were typical college students. Participants were tested in single-leg stance. Both the dominant leg (DL) and non-dominant leg (NDL) were tested with the participants shod (S) and barefoot (BF). Kinetic variables (vertical, medio-lateral [ML], antero-posterior [AP] maximum ground reaction forces (GRF), and center of pressure (COP) ML and AP) were measured by a Bertec force platform at 1000 Hz with participants S and BF. Each subject's stance was measured over 3 × 30-second intervals. No significant differences (p≥0.05) existed between groups for height, body mass, or age. Significant differences existed between groups for balance time, AP GRF in both BF and S conditions for both DL and NDL, and ML GRF in BF NDL and S DL and NDL conditions. D and ND in BF and S conditions with DL and NDL static stance demonstrate different AP and ML GRF when balancing over a 30-second time interval. Data may suggest that ND are more prone to lose their balance. Further investigation is warranted to understand whether individuals in the rehabilitative field and athletic populations can use dance therapy for injury prevention and rehabilitation.

摘要

本研究的目的是比较至少有七年舞蹈经验的女性舞者(D)和作为典型大学生的女性非舞者(ND)之间静态平衡的动力学差异。参与者接受单腿站立测试。优势腿(DL)和非优势腿(NDL)均在参与者穿着鞋子(S)和赤脚(BF)的情况下进行测试。动力学变量(垂直、内外侧[ML]、前后[AP]最大地面反作用力(GRF)以及压力中心(COP)的ML和AP)通过Bertec测力平台以1000Hz的频率在参与者穿着鞋子和赤脚的情况下进行测量。每位受试者的站立姿势在3个30秒的时间段内进行测量。两组在身高、体重或年龄方面不存在显著差异(p≥0.05)。两组在平衡时间、BF和S条件下DL和NDL的AP GRF以及BF NDL和S DL及NDL条件下的ML GRF方面存在显著差异。在BF和S条件下,DL和NDL静态站立的D组和ND组在30秒的时间间隔内保持平衡时表现出不同的AP和ML GRF。数据可能表明ND组更容易失去平衡。有必要进行进一步的研究,以了解康复领域的个体和运动员群体是否可以使用舞蹈疗法进行损伤预防和康复。
