This study aimed to explore the relationship between the functional fitness (FF) and health-related quality of life (HRQoL) in older adults, and to identify the key subdimensions of FF and HRQoL influencing their overall relationship.
This cross-sectional study was performed among 851 independent community members (65-84 years; men=402). The Senior Fitness Test and the Short Form 36 Health Survey were used to measure FF and HRQoL, respectively. A canonical correlation analysis was conducted using seven fitness variables as predictors of eight HRQoL variables to examine the relationship between FF and HRQoL.
The overall FF was positively correlated with the overall HRQoL in both men (canonical correlation=0.350) and women (canonical correlation=0.456). The up-and-go and 2-min step contributed the most to FF, and physical functioning contributed the most to HRQOL among men. Conversely, the up-and-go and 30-s chair stand contributed the most to FF, and physical functioning contributed the most to HRQoL in women.
There were positive and moderate relationships between overall FF and overall HRQOL in older adults. The FF has a significant influence on HRQoL, particularly physical functioning. The main FF components influencing the relationship between FF and HRQoL in men are balance and agility and aerobic endurance, whereas in women they are balance and agility and lower extremity muscle strength. Results from this study facilitate comprehensively understanding the relationship between FF and HRQoL, and generating critical insight into HRQoL improvement from the perspective of FF enhancement.
本研究旨在探讨老年人的功能健身（FF）与健康相关生活质量（HRQoL）之间的关系，并确定影响它们整体关系的FF和HRQoL的关键子维度。
本横断面研究在851名独立社区成员（65 - 84岁；男性 = 402名）中进行。分别使用高级健身测试和简短健康调查问卷36项来测量FF和HRQoL。使用七个健身变量作为八个HRQoL变量的预测因子进行典型相关分析，以检验FF与HRQoL之间的关系。
男性（典型相关系数 = 0.350）和女性（典型相关系数 = 0.456）的整体FF与整体HRQoL均呈正相关。起身行走测试和2分钟台阶测试对FF的贡献最大，而身体功能对男性的HRQoL贡献最大。相反，起身行走测试和30秒坐立测试对FF的贡献最大，而身体功能对女性的HRQoL贡献最大。
老年人的整体FF与整体HRQoL之间存在积极且中等程度的关系。FF对HRQoL有显著影响，尤其是身体功能方面。影响男性FF与HRQoL关系的主要FF组成部分是平衡与敏捷性以及有氧耐力，而在女性中则是平衡与敏捷性以及下肢肌肉力量。本研究结果有助于全面理解FF与HRQoL之间的关系，并从增强FF的角度对改善HRQoL产生关键见解。
