The purpose of this study was to investigate how individuals extends their stride length（ SL） when increasing gait speed by extending SL（Experiment-1）. Further, this study also examined the effects of increasing gait speed by extending SL while emphasizing push-off at the terminal stance phase on SL and gait speed（ Experiment-2）. In Experiment-1, eighteen healthy males performed 10-meter gait tasks in two conditions: 1） they just walked faster, and 2） they walked faster while extending their SL. Afterwards, participants were asked how they increased their SL. The survey observed that approximately 80% of the participants extended their SL in an attempt to extend the swinging leg forward. Experiment-2 was conducted on 14 participants who were not aware of push-off at the terminal stance phase when extending their SL in Experiment-1. They performed a 10-meter fast walk task with increasing the SL while emphasizing the push-off at the terminal stance phase. Experiment-2 observed that the emphasis on push-off resulted in more extended SL. These results suggest that although most of the participants extend their SL while attempting to extend the swinging leg forward, the emphasis on push-off at the terminal stance phase results in a more extended SL.
