背景：近年来，人们对北欧式健走（NW）的兴趣有所增加。然而，直接比较NW与正常行走（W），特别是在生态有效的环境是缺乏的。我们的研究的目的是比较西北和W，在长距离的自然山区环境。研究方法：21名受试者（13名男性/8名女性，年龄41 +/- 12岁，体重指数BMI 24.1 +/- 3.7）在两天内使用（NW）或不使用（W）步行杆行走三条不同的上坡路径（长度2.2/3.4/7 km）。监测心率（HR）、能量消耗（EE）、步长（SL）、步行速度（WS）、总步数（SN）和主观用力评分（RPE）。结果：NW组HR（+18%）和EE（+20%）高于W组，而RPE相似。NW的SN（-12%）较低，SL（+15%）较长。西北部的WS较高（1.64 vs 1.53 m s（-1））。结论：我们的数据证实，类似于以前的实验室研究，在一系列的步行变量的差异存在于NW和W之间时，在自然环境中进行。NW似乎增加EE相比，W，尽管类似的RPE。因此，NW可能是一种有用的有氧训练方式，用于体重控制和心肺适应性。
Background: Interest around Nordic Walking (NW) has increased in recent years. However, direct comparisons of NW with normal walking (W), particularly in ecologically valid environments is lacking. The aim of our study was to compare NW and W, over long distances in a natural mountain environment. Methods: Twenty one subjects (13 male/8 female, aged 41 +/- 12 years, body mass index BMI 24.1 +/- 3.7), walked three distinct uphill paths (length 2.2/3.4/7 km) with (NW) or without (W) walking poles over two separate days. Heart rate (HR), energy expenditure (EE), step length (SL), walking speed (WS), total steps number (SN) and rating of perceived exertion (RPE) were monitored. Results: HR (+18%) and EE (+20%) were higher in NW than in W whilst RPE was similar. SN (-12%) was lower and SL (+15%) longer in NW. WS was higher (1.64 vs. 1.53 m s(-1)) in NW. Conclusions: Our data confirm that, similarly to previous laboratory studies, differences in a range of walking variables are present between NW and W when performed in a natural environment. NW appears to increase EE compared to W, despite a similar RPE. Thus, NW could be a useful as aerobic training modality for weight control and cardiorespiratory fitness.
