Physical activities and sports in nature offer opportunities for leisure, health, and well-being. A randomized clinical trial (RCT) compared the effects of training, dualtask orienteering and single-task hiking in independent older adults (n = 90) allocated into three groups: orienteering group (OG), hiking group (HG) and control group (CG). Timed Up and Go (TUG) tests, including a dual-task (TUG-DT), and cognitive tests were administered. Differences were analyzed by Generalized Estimating Equations (GEE) and the effect size (ES) was calculated. Unpaired and paired tests were used for the evaluation of basic differences and after 24 weeks of intervention.
This RCT highlights the interaction effects between groups and time. Only the OG in TUGDT reduced by 6 s, with change of 42% (ES=0.77). Likewise, Dual TUG + cognitive stops (TUG-DT+ CS) and Dual TUG + cognitive stops + cognitive errors (TUG-DT + CS + CE), reduced 7 (ES=0.85) and 8 (ES=0.90) seconds (<0.001). The task cost improved by 75% for OG and 24% for HG (p = 0.001), with an ES of 0.56 for OG. For cognition, there was a 49.2% increase (ES=2.00) for OG and 16.5% for HG in executive functions and visuospatial skills, a 31.4% increase (ES=1.64) for OG and 14.7% for HG in processing speed, and a 39.8% increase (ES=1.62) for OG and 6.5% for HG in memory. All interactions were <0.001.

户外活动和运动为休闲、健康和幸福感提供了机会。一项随机临床试验(RCT)比较了训练、定向越野双重任务和独立老年人的单一任务徒步旅行(n=90)的效果,将其分为三组:定向越野组(OG)、徒步旅行组(HG)和对照组(CG)。进行了计时起立行走(TUG)测试,包括双重任务(TUG-DT)和认知测试。通过广义估计方程(GEE)分析差异,并计算效应量(ES)。使用非配对和配对检验评估基本差异和 24 周干预后的差异。
这项 RCT 强调了组间和时间的交互作用。只有 OG 在 TUGDT 中减少了 6 秒,变化率为 42%(ES=0.77)。同样,双重 TUG+认知停止(TUG-DT+CS)和双重 TUG+认知停止+认知错误(TUG-DT+CS+CE)减少了 7(ES=0.85)和 8(ES=0.90)秒(<0.001)。OG 的任务成本提高了 75%,HG 的任务成本提高了 24%(p=0.001),OG 的 ES 为 0.56。对于认知功能,OG 的执行功能和视空间技能提高了 49.2%(ES=2.00),HG 提高了 16.5%;OG 的处理速度提高了 31.4%(ES=1.64),HG 提高了 14.7%;OG 的记忆提高了 39.8%(ES=1.62),HG 提高了 6.5%。所有交互作用均<0.001。
