| Outline of Final Research Achievements |
Humans are able to perform skillful movements by coordinating muscles throughout the entire body. Direct and dynamic interactions between body parts, as well as neural mechanisms, contribute to muscular coordination. We focused on tension propagation based on tensegrity structure, which consists of muscles and fascia for providing tension and skeleton for resisting compressive forces inside the body. Therefore, we conducted a study on design approach to constructing the tensegrity structure outside the body and effects of the tensegrity structure on body movements. A fundamental unit was devised that can expand to accommodate the user's body size. This unit can be used to create tensegrity structures consisting of multiple units. Additionally, a method was developed for wearing the tensegrity structures on the body while transmitting tension. Furthermore, approaches to improving the effectiveness of tension propagation within the body were investigated.

筋緊張の伝達経路はアナトミー・トレインと呼ばれ，経路網内で張力変化が伝達することで，全身を使った連続的な動きや姿勢維持に寄与している．解剖学的知見も示され，運動療法において実践的に活用されている．経路上の筋が連動し，離れた部位が協調してより大きな力を発揮させたり，負荷を分散させたりなどの，知見の活用を範疇に含めた張力伝達機能のさらなる解明が期待される．
