This study examined the relationships between measured values of physiological and mechanical load during Walking (W) and Nordic Walking (NW) at various speeds (0.97-2.08 m/s) in healthy old and middle-aged subjects in order to clarify the effectiveness of NW as a health-enhancing physical activity for individuals with low physical fitness. NW required a significantly higher VO2 than W at a walking speed of 1.25 m/s, and tended to show a higher VO2 requirement than W at various other speeds, the difference ranging from 9% to 13%. The step length for NW was significantly greater than that for W. Furthermore, although both NW and W demonstrated higher peak compressive force and peak shear force on the knee joint with increased speed, those during NW were significantly greater, and the difference was extended at faster walking speed. For compressive force and shear force, the speed at intersection (NW and W) of the regression line was 1.48 m/s. Based on these findings, it is thought that although high-speed NW is a useful health-enhancing physical activity, it is necessary to ensure that the knee joint is not subjected to excessive loading.<br>
