The aim of this study was to investigate alterations in physical fitness and anthropometric parameters as well as depression symptoms among the elderly after participation in the "National Walking Program" (Portugal). The sample consisted of 26 elderly people over six months with a total of 72 exercise sessions. The exercise sessions consisted of aerobics (walking and running) and strength and flexibility exercises. Participants were assessed pre- and post-intervention for physical fitness with the Rikli & Jones test. The anthropometric measurements were assessed with a bioimpedance scale and a stadiometer, and depression with Yesavage's Geriatric Depression Scale. Physical activity was only assessed with an accelerometer at the pre-intervention phase. For statistical analysis, the student t test for paired samples was performed using SPSS 21 software. Statistically significant improvements were found in depressive symptoms (p ≤ 0.001), and in all physical fitness tests (p ≤ 0.05) except for flexibility tests (p ≥ 0.05). Waist circumference reduction also showed the positive effects of the intervention (p = 0.031). The conclusion drawn is that participation in the "National Walking Program" for 6 months was effective in improving the physical and psychological health of the elderly.
本研究旨在调查参与（葡萄牙）“全国步行计划”的老年人的体能、人体测量参数变化以及抑郁症状。样本包括26名老年人，历时六个月，共进行了72次锻炼。锻炼包括有氧运动（步行和跑步）以及力量和柔韧性练习。干预前后，使用里克利和琼斯测试对参与者的体能进行评估。使用生物电阻抗秤和身高计评估人体测量指标，使用耶萨维奇老年抑郁量表评估抑郁情况。仅在干预前阶段使用加速度计评估身体活动。使用SPSS 21软件对配对样本进行学生t检验以进行统计分析。发现抑郁症状（p≤0.001）以及除柔韧性测试外的所有体能测试（p≤0.05）均有统计学显著改善（柔韧性测试p≥0.05）。腰围减小也显示出干预的积极效果（p = 0.031）。得出的结论是，参与为期6个月的“全国步行计划”对改善老年人的身心健康有效。
