Segmental response of the human body to changes in the interrelationship with the environment

Abstract

In general, it may be difficult to secure the amount of activity due to pain. Therefore, there is a need to pay attention to qualitative aspects of exercise, such as body balance control. In human body, the mass ratio of the trunk including the head is said to occupy 60% of the whole body. Therefore, evaluation of the segmentality of the head and trunk in posture / motion control strategy is important as an indicator of stability and efficiency of motion. In this research, we investigated human's segmental attitude control using an acceleration sensor based on a cantilever structure control model. As a result, a segmental response of the body occurred in the change of the relationship between the environment and the body. Regarding human body balance control, the possibility that each segment of the body responds to each frequency band was considered.
