Magnitudes and temporal sequencing of load kinematics and kinetics for single-handed pulls.

Abstract

This paper provides data regarding kinematics and kinetics during single-handed, submaximal pulls about various locations in the frontal plane for three loads (6, 12 and 18% lean body mass). Pulls were executed at two relative heights (elbow and eye) through two parasagittal planes also relative to subject morphology. Results indicate that in most cases load and pull location influence the occurrence of measured kinetic variables within a pull cycle but have little effect on the magnitude of these values. Findings from this study suggest that analyses of kinematic and kinetic movement histories may be required for a better understanding of the mechanical loading profiles upon operators engaged in such manual materials handling activities.
