The aim of this study is to examine the age-related changes in the toe grip strength and its differences from hand grip strength and knee extension strength using cross-sectional data.
Of participants aged 65 years over who underwent health checkups for lifestyle-related diseases in 2018, 307 men and women met the criteria. Toe grip strength, hand grip strength, and knee extension strength were also measured as optional tests. The participants were divided into five groups categorized by every 5 years of age (Group 65-85). The data were analyzed with multiple comparisons using the linear mixed multilevel model to examine the following categories: association between age and muscle strength, differences in the pattern of change, and gender, using the 65-69 years group as a reference.
In men, there were interaction effects between the factors of age and muscle, but in women there were not. Toe grip strength was significantly lower in Group 70, 75, 80, and 85 in men, lower in Group 85 than in 65 in women. Hand grip strength was significantly lower in Group 85 than in 65 in both men and women. There was no significant difference in knee extension strength among the age groups for both men and women.
The decline in toe grip strength may occur earlier and in a different pattern from hand grip strength and knee extension strength in men.
本研究旨在使用横断面数据检查与年龄相关的足趾握力变化及其与手握力和膝关节伸展力的差异。
在 2018 年接受与生活方式相关疾病健康检查的 65 岁以上参与者中,有 307 名男性和女性符合标准。足趾握力、手握力和膝关节伸展力也作为可选测试进行测量。参与者被分为五组,每组以每 5 岁为一个年龄段(65-85 岁组)。使用线性混合多级模型进行多重比较分析,以检查以下类别:年龄与肌肉力量之间的关系、变化模式的差异以及性别,以 65-69 岁组为参考。
在男性中,年龄和肌肉的因素之间存在交互作用,但在女性中则没有。男性中,70、75、80 和 85 组的足趾握力显著低于 65-69 岁组,85 组的握力显著低于 65 岁组。男性和女性中,85 岁组的手握力均显著低于 65 岁组。男性和女性的膝关节伸展力在各年龄组之间无显著差异。
与手握力和膝关节伸展力相比,男性的足趾握力下降可能更早且模式不同。
