This study examined the effects of an instructed structured Nordic walking (NW) exercise program on the functional capacity of older sedentary people. Volunteers were randomly assigned to an NW group (68.2 ± 3.8 yr old) or control group (69.9 ± 3.0 yr old). Before and at the end of the 9-wk intervention, functional tests and 2-dimensional ground-reaction-force (GRF) patterns of normal (1.40 m/s) and fast (1.94 m/s) walking speeds were measured. The intervention included a 60-min supervised NW session on an inside track twice a week for 9 wk. The mean changes in functional tests differed between groups significantly. Gait analyses showed no significant differences between the groups on any GRF parameters for walking speed either before or after the intervention. The study showed that NW has favorable effects on functional capacity in older people and is a suitable form of exercise for them.
本研究考察了有指导的结构化北欧式健走（NW）锻炼计划对久坐不动的老年人功能能力的影响。志愿者被随机分为NW组（68.2±3.8岁）或对照组（69.9±3.0岁）。在为期9周的干预前后，测量了正常步行速度（1.40米/秒）和快速步行速度（1.94米/秒）下的功能测试以及二维地面反作用力（GRF）模式。干预包括在室内跑道上每周两次、每次60分钟的有监督的NW训练，持续9周。两组在功能测试中的平均变化有显著差异。步态分析表明，干预前后两组在任何步行速度的GRF参数上均无显著差异。该研究表明，NW对老年人的功能能力有积极影响，是适合他们的一种锻炼形式。
