title: Techniques and equipment for muscle mechanics.
abstract: The individual in vivo mechanical properties of muscle groups are not well known, and these data are important in simulations of a subject's movements, and analysis of measured movements. Discrepancies in the force-velocity relation between in vivo and in vitro measurements have been documented in previous investigations. A powerful, high precision dynamometer was designed and built to make in vivo tests on the elbow and ankle joints. Test data obtained with this machine did not exhibit the same discrepancies observed in previous experiments, which leads to the conclusion that the previous discrepancies resulted from the test method used.
