Sorted by: Date Added To NTRS in Descending order An extensometer for global measurement of bone strain suitable for use in vivo in humans Author(s): Perusek, G. P.; Davis, B. L.; Sferra, J. J.; Courtney, A. C.; D'Andrea, S. E. Abstract: An axial extensometer able to measure global bone strain magnitudes and rates encountered during physiological activity, and suitable for use in vivo in human subjects, is described. The extensometer uses paired capacitive ... NASA Center: Glenn Research Center Publication Year: 2001 Added to NTRS: 2006-08-02 Document ID: 20040112576 Locomotion in a rotating space station: a synthesis of new data with established concepts Author(s): Davis, B. L.; Cavanagh, P. R.; Perry, J. E. Abstract: Despite technical problems associated with designing a rotating space station it is still thought that such a device may provide a more tolerable work environment and prevent some of the physiological changes that currently ... NASA Center: Johnson Space Center Publication Year: 1994 Added to NTRS: 2006-08-02 Document ID: 20040089766 Decomposition of superimposed ground reaction forces into left and right force profiles Author(s): Davis, B. L.; Cavanagh, P. R. Abstract: The process of collecting ground reaction force data by mounting a forceplate beneath a treadmill belt has the advantage that numerous walking trials can be analyzed without the problem of subjects 'targeting' their ... NASA Center: NASA (non Center Specific) Publication Year: 1993 Added to NTRS: 2006-08-02 Document ID: 20050000491 Quantifying Biomechanical Characteristics of Jumping Exercises in 1G and in Simulated and True Microgravity Author(s): Davis, B. L.; DAndrea, S. E.; Perusek, G.; Orlando, T. Abstract: Exercise in microgravity is one of the most promising countermeasures to the dual problems of space flight-induced bone loss and muscle atrophy. Although exercise in microgravity has been studied extensively from a metabolic ... NASA Center: Glenn Research Center, Goddard Space Flight Center Publication Year: 1999 Added to NTRS: 2004-11-03 Document ID: 20000020486 Ground Reaction Forces During Locomotion in Simulated Microgravity Author(s): Davis, B. L.; Cavanagh, Peter R.; Sommer, H. J., III; Wu, G. Abstract: Significant losses in bone density and mineral, primarily in the lower extremities have been reported following exposure to weightlessness. Recent investigations suggest that mechanical influences such as bone deformation ...
