The purpose of the current study was to identify significant predictors of walking speed (WS) among community-dwelling older adults, as it is one of the most representative measures of functioning in their daily lives. Seventy-seven (24 adult men, 26 adult women, and 27 older-adult women) community-dwelling older adults (73.7 ± 4.9 years) performed two assessments, over a 12-month period. Several physical, cognitive, and psychological tests were performed, as well as assessing the preferred WS. Multiple linear regression, stratified by gender, was used to identify significant predictors of future WS. For the adult men, walking and functional performances at the first assessment predicted 71.9%; for adult women, reaction time, walking, and balance performance predicted 64.4%; and, for the older-adult women, fast walking and reaction time predicted 48.2% of the variance of future WS. Clinicians should consider including different exercises for each group of older adults to evaluate and preserve functional abilities.

本研究的目的是确定社区居住老年人步行速度 (WS) 的重要预测因子，因为它是日常生活中最具代表性的功能指标之一。77 名（24 名成年男性、26 名成年女性和 27 名老年女性）居住在社区的老年人（73.7 ± 4.9 岁）在 12 个月内进行了两次评估。进行了几项身体、认知和心理测试，并评估了首选的 WS。按性别分层的多元线性回归用于确定未来 WS 的重要预测因子。对于成年男性，第一次评估的步行和功能表现预测为 71.9%；对于成年女性，反应时间、步行和平衡能力预测为 64.4%；而且，对于年长的女性来说，快走和反应时间预测了未来 WS 方差的 48.2%。临床医生应考虑对每组老年人进行不同的锻炼，以评估和保持功能能力。
