The purpose of this study was to investigate the effects of changes in gait pitch, gait stride, and arm swing stroke in Tube walking（TW） on respiratory circulatory parameters, muscle electrical activities, and gait patterns. Seven male subjects who were skilled Nordic walker and have regularly exercise in their daily lives, voluntarily participated in the study. This experiment was conducted at four speeds, 60,70,80 and 90 m/min, with a treadmill. V4 O2 and HR were averaged every 30 seconds, and the OMNI scale was recorded for the all conditions at the end of each speed. Surface electromyography (EMG） were recorded from the triceps brachii（TB）, deltoid muscle（DM） and vastus lateralis（VL）.
The results showed that all muscle activities of Nw-Tw were similar to that of Nw. In addition, Nw-Tw tended to be higher than Wk-Tw but it was not significant. Nw-Tw also acquired higher exercise intensity than Wk-Tw in the respiratory circulatory parameters. It was concluded that Nw-Tw could achieve exercise intensity equivalent of the NW.
