Department of Exercise Science, University of Massachusetts, Amherst, MA 1989 Sep:252 pages
This study was performed with two purposes in mind. The first was to modify an existing biodynamic model for pushing and pulling so that it would reflect new technological capabilities. The second purpose was to validate the modified model in the laboratory with a broad anthropometric population. Included in this report was a discussion of the methods used for the study including calculations of various forces, model implementation, laboratory validation studies, experimental design and protocol, and the data acquisition and analysis functions. The results presented included static calibration experiments in which measurements of dependent variables, hand forces, ground reaction forces and ratios, support time variables, erector spinae muscle forces, and rectus abdominis muscle forces were obtained. Also reported were predictions for dependent variables for validation and ground reaction forces. A model of the predicted muscle forces was described and the differences between measured and model predicted variables were determined. The effects of body weight on model performance were considered.
