An object of the present invention is to provide a support suit based on biomechanics for improving the efficiency of posture and movement. In particular, it is a support suit with a part reinforced with a material resembling the normal elasticity of human body components. This tension-strengthening part follows the structure of the musculoskeletal system and appropriately supports the posture and movements of children and adults with motor dysfunction, thereby improving the efficiency of workers and athletes' activities. [Selection] Figure 9本発明は、姿勢と動作の効率化を図る生体力学に基づくサポートスーツを課題とする。特に人体構成要素の通常の弾力性に似せた材料で強化された部分のあるサポートスーツである。この張力強化部分は筋骨格系の構造に従い、運動機能障害のある子供や大人の姿勢と動作を適切に支え、労働者やアスリートの活動の効率化を図る。【選択図】図9
