| Outline of Final Research Achievements |
Skeletal muscle can prevent bone atrophy simply by maintaining skeletal muscle mass. Furthermore, it can be expected to prevent degenerative changes in various biological functions such as age-related muscle weakness (sarcopenia). Using a wearable gait analysis system, we examined the activity of the lower limb antigravity muscles in closer detail from the perspective of biomedical engineering and kinematics. From the information gathered in these examinations, we develop a “load-controlled treadmill” that can apply effective stimulation and stress to lower limb antigravity muscles, such as the soleus, by making the user proactively move the ankles in order to move the walking surface. It was clarified that the use of a load-controlled treadmill was able to provide effective stimulation to the antigravity muscles of the lower limbs.

本研究で開発した，地面反力を計測するフォースプレートを搭載し推進力をフィードバックすることによる負荷制御機能を有する，効果的な歩行・走行トレーニングが可能な「負荷制御型トレッドミル」および簡易に身体運動計測が可能な「ウェアラブルセンサ」を，フィットネスジムに普及することによって，サルコペニアなどの原因となる下肢抗重力筋の減弱を防止できる．さらにウェアラブルセンサに基づく運動解析結果を併用した効果的なトレーニングによって，実寿命に限りなく近い健康寿命の維持に貢献することが期待できる．
