Health-related fitness has been reported to be associated with improved quality of life (QoL) in the elderly. Health-related fitness is comprised of several dimensions that could be enhanced by specific training regimens. It has remained unclear how various dimensions of health-related fitness interact with QoL in postmenopausal women.
The purpose of the current study was to investigate the relationship between the dimensions of health-related fitness and QoL in elderly women.
A cohort of 408 postmenopausal women in a rural area of Taiwan was prospectively collected. Dimensions of health-related fitness, consisting of muscular strength, balance, cardiorespiratory endurance, flexibility, muscle endurance, and agility, were assessed. QoL was determined using the Short Form Health Survey (SF-36). Differences between age groups (stratified by decades) were calculated using a one-way analysis of variance (ANOVA) and multiple comparisons using a Scheffé test. A Spearman's correlation analysis was performed to examine differences between QoL and each dimension of fitness. Multiple linear regression with forced-entry procedure was performed to evaluate the effects of health-related fitness. A P-value of <0.05 was considered statistically significant.
Age-related decreases in health-related fitness were shown for sit-ups, back strength, grip strength, side steps, trunk extension, and agility (P<0.05). An age-related decrease in QoL, specifically in physical functioning, role limitation due to physical problems, and physical component score, was also demonstrated (P<0.05). Multiple linear regression analyses demonstrated that back strength significantly contributed to the physical component of QoL (adjusted beta of 0.268 [P<0.05]).
Back strength was positively correlated with the physical component of QoL among the examined dimensions of health-related fitness. Health-related fitness, as well as the physical component of QoL, declined with increasing age.
据报道，与健康相关的体能与老年人生活质量（QoL）的改善有关。与健康相关的体能由几个维度组成，可通过特定的训练方案得到增强。绝经后女性中，与健康相关的体能的各个维度如何与生活质量相互作用仍不清楚。
本研究的目的是调查老年女性与健康相关的体能维度与生活质量之间的关系。
前瞻性收集了台湾农村地区408名绝经后女性。评估了与健康相关的体能维度，包括肌肉力量、平衡能力、心肺耐力、柔韧性、肌肉耐力和敏捷性。使用简短健康调查问卷（SF-36）确定生活质量。使用单因素方差分析（ANOVA）计算年龄组（按十年分层）之间的差异，并使用谢弗检验进行多重比较。进行斯皮尔曼相关性分析以检查生活质量与每个体能维度之间的差异。采用强制进入程序进行多元线性回归，以评估与健康相关的体能的影响。P值<0.05被认为具有统计学意义。
仰卧起坐、背部力量、握力、侧步、躯干伸展和敏捷性方面出现了与年龄相关的与健康相关体能的下降（P<0.05）。还证明了与年龄相关的生活质量下降，特别是在身体功能、因身体问题导致的角色限制和身体成分得分方面（P<0.05）。多元线性回归分析表明，背部力量对生活质量的身体成分有显著贡献（调整后的β为0.268 [P<0.05]）。
在所检查的与健康相关的体能维度中，背部力量与生活质量的身体成分呈正相关。与健康相关的体能以及生活质量的身体成分随年龄增长而下降。
