Application of dual number matrices, screw calculus, and associated analytical methods. Experimental techniques for biomechanical analysis of human movement are examined. Techniques evaluated include data acquisition and analysis by computer, force platform analysis, strength assesment, planar and three-dimensional videography, data reduction and smoothing, body segment parameter determination, electromyography, and biomechanical modeling. Basic structure and function of skeletal muscle are examined at the microscopic and macroscopic levels. Muscle adaptations in response to aging, disease, injury, exercise and disuse are considered.
Special emphasis is placed on the relationship between muscle structure and muscle mechanics.
