Middle-aged women have less postural control than younger women. The Star Excursion Balance Test is a functional and inexpensive postural control measurement tool that is sensitive to age-related changes in balance.
The middle-aged females will experience lower excursion scores compared with the younger women.
Fifty-three healthy, recreationally active women were divided into 2 groups: adult-aged (n = 29; age range, 23-39 years) and middle-aged (n = 24; age range, 40-54 years). Each participant performed 3 reaches for 3 trials (anteromedial, medial, posteromedial) in a randomized order. The 3 reach trials were converted to a normalized value (percentage of participant's height) and assessed as an overall mean for the 1-way analysis of variance. Intraclass correlation coefficients and 95% confidence intervals were calculated.
No differences were found for body mass index and height; however, age was different between groups (P < 0.01). Intraclass correlation coefficient(2,3) values for the 3 directions ranged from 0.72 to 0.97. The adult-aged women were able to reach farther in all 3 directions when tested with the Star Excursion Balance Test (6.8-7.6 cm, P < 0.05).
Lower postural control scores based on the Star Excursion Balance Test were found for the older women. The younger women were able to reach approximately 7 cm farther during the anterior, anteromedial, and posteromedial excursions.
中年女性的姿势控制能力比年轻女性差。星状偏移平衡测试是一种功能性且经济实惠的姿势控制测量工具，对平衡与年龄相关的变化敏感。
中年女性的偏移得分将低于年轻女性。
53 名健康、有业余运动习惯的女性被分为 2 组：成年组（n = 29；年龄范围，23-39 岁）和中年组（n = 24；年龄范围，40-54 岁）。每位参与者以随机顺序进行 3 次尝试（前内侧、内侧、后内侧）。将 3 次的偏移距离转换为归一化值（参与者身高的百分比），并作为单向方差分析的总体平均值进行评估。计算了组内相关系数和 95%置信区间。
体重指数和身高无差异；然而，组间年龄不同（P < 0.01）。3 个方向的组内相关系数（2,3）值范围为 0.72 至 0.97。在星状偏移平衡测试中，成年组在所有 3 个方向上的偏移距离都更远（6.8-7.6cm，P < 0.05）。
根据星状偏移平衡测试，老年女性的姿势控制得分较低。年轻女性在前侧、前内侧和后内侧的偏移中，能够多移动大约 7 厘米。
