Passive mechanical properties of human gastrocnemius muscle-tendon units
Background The passive mechanical properties of skeletal muscletendon units are important because they determine the amount of motion available at joints. Human gastrocnemius muscle-tendon units are of particular interest because this muscle is prone to develop contractures, may have a role in lower limb overuse injuries, and is a common site of muscle tears. This workshop provides an introduct...
متن کاملPassive mechanical properties of human gastrocnemius muscle tendon units, muscle fascicles and tendons in vivo.
This study provides the first in vivo measures of the passive length-tension properties of relaxed human muscle fascicles and their tendons. A new method was used to derive passive length-tension properties of human gastrocnemius muscle-tendon units from measures of ankle stiffness obtained at a range of knee angles. Passive length-tension curves of the muscle-tendon unit were then combined wit...
متن کاملMechanical coupling between the hemithoraces in humans.
Unilateral airway occlusion permits measurement of single lung function. Since the results suggest that the occluded lung influences the mobility of the contralateral hemithorax, we wanted to test this hypothesis. In eight healthy subjects, we measured, using computed tomography, lung parenchymal area and inner rib cage parasagittal and transverse diameters at three different levels and at maxi...
متن کاملMechanical properties of aponeurosis and tendon of the cat soleus muscle during whole-muscle isometric contractions.
Recent studies have suggested that the mechanical properties of aponeurosis are not similar to the properties of external tendon. In the present study, the lengths of aponeurosis, tendon, and muscle fascicles were recorded individually, using piezoelectric crystals attached to the surface of each structure during isometric contractions in the cat soleus muscle. We used a surgical microscope to ...
متن کاملElectromechanical Coupling between Skeletal and Cardiac Muscle
Skeletal myoblasts form grafts of mature muscle in injured hearts, and these grafts contract when exogenously stimulated. It is not known, however, whether cardiac muscle can form electromechanical junctions with skeletal muscle and induce its synchronous contraction. Here, we report that undifferentiated rat skeletal myoblasts expressed N-cadherin and connexin43, major adhesion and gap junctio...
