Concerning most of track-and-field athletics such as the marathon, it is important to elucidate the flow around track runners, and to evaluate their air resistances. In wind-tunnel experiments which are the most effective approach to the study, the moving-belt device is indispensable for precise aerodynamic measurements considering the ground effect. In the present study, the authors develop the device, and show its basic performance such as the distributions of time-mean velocity and turbulent intensity above the moving-belt using a hot-wire anemometer.
