Nordic walking (NW) is a full body training that can be performed with special pole, and has been recognized as an effective out-door activity which can improve the strength of upper extremity. Most previous stud-ies mainly analyzed the effect of NW on the strength of dominant (DN) hand-grip strength, however, a clear scientific examination is needed whether nondominant (NDN) extremity can also be ameliorated by the NW. Therefore, the aim of our study is to investigate the effectiveness of 8 weeks NW training on the NDN handgrip and shoulder strength in healthy middle-aged women. 29 subjects were randomly divided into three groups: Nordic walking group (NWG, n=10), brisk walking group (BWG, n=11), and control group (CG, n=8). Handgrip and shoulder strength were measured by the hand dynamometer and isokinetic ma-chine. NW training was performed 3 times a week, and had 10-min warm-up, 40-min main program consisted of ALFA (Attention, Long arms, Flat poles, Adaptes) technique and Turbo walking, and 10-min cool-down. In handgrip strength of DN hand and the shoulder flexor strength in the both sides, NWG and BWG showed significantly higher value compared to CG. In the NDN hand, NWG also showed significant-ly higher strength compared to CG, however, there was no significant difference in the handgrip strength/weight among groups. In NDN shoulder extension, significantly higher improvement was found in NWG and BWG compared to that of CG. In conclusion, our study showed that NW can improve the strength of upper extremity in sub-jects, and can be better approach to improve the NDN handgrip strength than brisk walking method could.
