Abstract

BACKGROUND

The decline in lower limb muscle strength, one of the risk factors for falling in the older adults, puts older persons at an increased risk of falling. The assessment of the lower limb muscle strength is very important.

OBJECTIVE

The purpose of this study was to construct the equation for predicting knee extensor muscle strength based on demographic data and the results of the Five-Time Sit-to-Stand Test (FTSST).

METHODS

A total of 121 healthy elders (mean age ) were asked to complete the FTSST and submit the demographic information. By using a stationary push-pull dynamometer, the knee extensor strength of each participant was assessed. The multiple regression analysis was used to explore knee extensor strength prediction equation.

RESULTS

The findings demonstrated that the knee extensor strength equation was developed using variables obtained from gender, weight, and time to complete the FTSST. The equation was found to have a high correlation () and 70.1% estimation power. Its formula was as follows: Knee extensor (gender; or ) 0.189 (weight) - 2.617 (time to complete the FTSST). However, there was an estimating error in this equation of 4.72 kg.

CONCLUSION

The determining factors influencing knee extensor strength, which can be utilized to estimate the strength in elderly individuals, are demographic variables including gender, weight, and the time taken to complete the FTSST.

摘要

背景

下肢肌肉力量下降是老年人跌倒的危险因素之一，会增加老年人跌倒的风险。评估下肢肌肉力量非常重要。

目的

本研究旨在基于人口统计学数据和五次坐立试验（FTSST）结果构建预测膝伸肌力量的方程。

方法

共121名健康老年人（平均年龄 ）被要求完成FTSST并提交人口统计学信息。使用固定式推拉测力计评估每位参与者的膝伸肌力量。采用多元回归分析探索膝伸肌力量预测方程。

结果

研究结果表明，膝伸肌力量方程是使用从性别、体重和完成FTSST的时间中获得的变量建立的。该方程具有高度相关性（ ）和70.1%的估计能力。其公式如下：膝伸肌 （性别； 或 ） + 0.189（体重） - 2.617（完成FTSST的时间）。然而，该方程存在4.72 kg的估计误差。

结论

影响膝伸肌力量的决定因素包括性别、体重和完成FTSST所需时间等人口统计学变量，可用于估计老年人的力量。
