PROBLEM TO BE SOLVED: To provide a method for acquiring the exercise condition of users trunk, the method being capable of easily and correctly measuring the exercise condition of the trunk.SOLUTION: The method for acquiring the exercise condition of the trunk on the basis of the deformation amount of the surface of a living body causes a sensor device to measure the deformation amount of measurement sections of at least three places including a first measurement section to a third measurement section regulated on the surface of the living body, and calculates the bending/extending amount, lateral bending amount, and rotation amount of the trunk on the basis of the deformation amount, thereby acquiring the exercise condition of the trunk.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 被験者の体幹の運動状態を容易に、かつ正確に計測することができる体幹の運動状態を取得する方法を提供する。【解決手段】 生体表面の変形量に基づいて体幹の運動状態を取得する方法であって、生体表面に規定された第1計測部位~第3計測部位を含む少なくとも3か所の計測部位の変形量をセンサ装置によって測定し、前記変形量に基づいて、前記体幹の屈曲・伸展量、側屈量及び回旋量を算出することによって、体幹の運動状態を取得する方法。【選択図】 図1
