The aim of this study was to investigate the impact of an 8-week Nordic walking (NW) intervention on older adult gait patterns and postural alignment. Twelve healthy older adults aged 60-80 years (8 female, 4 male) participated, all performing two 6-min walk tests (one with poles [WP], one without poles [NP]) and six 5-m walk trials (3 WP, 3 NP) at pre- and posttesting. Gait and postural variables were compared between poling conditions (i.e., WP to NP) as well as before and following the intervention. Following training, pole use resulted in various gait changes including: longer stride, faster gait, and increased power generation at the hip (H3) and power absorption at the knee (K1 and K4). We conclude that an initial 8-week training period is necessary for novice NW to perfect technique and to restore gait to a more natural, normal pattern following training.
本研究的目的是调查为期8周的越野行走（NW）干预对老年人步态模式和姿势对齐的影响。12名年龄在60至80岁之间的健康老年人（8名女性，4名男性）参与了研究，所有人在测试前和测试后都进行了两次6分钟的步行测试（一次使用手杖[WP]，一次不使用手杖[NP]）以及六次5米的步行试验（3次WP，3次NP）。比较了使用手杖条件下（即WP与NP）以及干预前后的步态和姿势变量。训练后，使用手杖导致了各种步态变化，包括：步幅更长、步态更快，以及髋部（H3）产生的力量增加和膝盖（K1和K4）吸收的力量增加。我们得出结论，对于新手越野行走者来说，最初为期8周的训练期对于完善技术以及在训练后将步态恢复到更自然、正常的模式是必要的。
