Abstract
- The elastic and mechanical behaviour of isolated papillar muscle was studied in aged and in young rats. The spontaneous fall in tension (stress relaxation phenomenon) and the duration of the active state of the contractile element during the isometric and isotonic contraction were greater in aged than in young rats. The elastic properties of the elements in parallel and in series and the intensity of the active state in the contractile elements, on the contrary, did not exhibit any significant difference between aged and young rats.
