[Purpose] The aim of this study was to assess the effect of Nordic pole walking on the electromyographic activities of upper extremity and lower extremity muscles. [Subjects and Methods] The subjects were randomly divided into two groups as follows: without Nordic pole walking group (n=13) and with Nordic pole walking group (n=13). The EMG data were collected by measurement while the subjects walking on a treadmill for 30 minutes by measuring from one heel strike to the next. [Results] Both the average values and maximum values of the muscle activity of the upper extremity increased in both the group that used Nordic poles and the group that did not use Nordic poles, and the values showed statistically significant differences. There was an increase in the average value for muscle activity of the latissimus dorsi, but the difference was not statistically significant, although there was a statistically significant increase in its maximum value. The average and maximum values for muscle activity of the lower extremity did not show large differences in either group, and the values did not show any statistically significant differences. [Conclusion] The use of Nordic poles by increased muscle activity of the upper extremity compared with regular walking but did not affect the lower extremity.
[目的]本研究旨在评估北欧式健走对上肢和下肢肌肉肌电活动的影响。[对象与方法]将受试者随机分为以下两组：非北欧式健走组（n = 13）和北欧式健走组（n = 13）。在受试者在跑步机上行走30分钟（从一次足跟触地到下一次足跟触地）的过程中，通过测量收集肌电数据。[结果]使用北欧式健走杖组和未使用北欧式健走杖组的上肢肌肉活动平均值和最大值均增加，且这些值显示出统计学上的显著差异。背阔肌肌肉活动平均值有所增加，但差异无统计学意义，尽管其最大值有统计学上的显著增加。两组下肢肌肉活动的平均值和最大值均未显示出较大差异，且这些值未显示出任何统计学上的显著差异。[结论]与常规行走相比，使用北欧式健走杖增加了上肢的肌肉活动，但对下肢没有影响。
