Exceeding the limits of the human body is a fundamental human desire. We revealed that a wearable robot can reduce sprint times of non-elite runners, indicating the transcendence of personal physical limitations through a wearable robot. Compared with the no-suit condition, the sprint time of 200-m sprinting in the suit-on condition decreased by 0.97 s on average. Specifically, the sprint times in the 0- to 100-m and 100- to 200-m sections were reduced by 0.68 and 0.30 s on average, respectively. And we found a linear correlation between the rate of decrease in the sprint time and rate of increase in the step frequency during the sprints. This finding indicates that the exosuit served to shorten the sprint time by increasing the step frequency.
