[PROBLEMS] For the purpose of promoting health and improving the risk of dementia, the effects of the walking method with wide stride and step are recognized and recommended, but it is effective to announce step by step and step information. There is no system that supports walking and running smoothly. SOLUTION: The distance between two limbs for each step of walking / running is measured using a contact or non-contact distance measuring device, and the walking / running state of the user is grasped based on comparison with a set management standard. Based on this information, the user can support walking and running at the target level, and the PDCA cycle of efficient walking and running behavior can be performed in a short time to show the user's health progress and competition. Providing a walking and running behavior presentation system that enables presentation of behaviors for people. [Selection] Figure 3【課題】健康増進や認知症のリスク改善を目的に、歩幅や歩隔を広げた歩行法の効果が認められ推奨されているが、一歩毎の歩幅や歩隔の情報を告知し、効果的な歩・走行の支援を行うシステムが存在しない。【解決手段】歩・走行の一歩毎の二肢の隔たりを接触または非接触間隔計測機器を用いて測定し、設定された管理基準との比較を基に使用者の歩・走行の状態を把握し、その情報をもとに目標レベルの歩・走行が行える様に支援し、効率の良い歩・走行行動のPDCAサイクルを短時間で回すことにより、使用者の健康増進行動の提示、並びに競技者用行動の提示を可能とする歩行および走行行動提示システムの提供。【選択図】図3
