Maximum acceptable forces of dynamic pushing: comparison of two techniques

摘要

The purpose of this experiment was to investigate maximum acceptable initial and sustained forces while performing a push of 7.6 m, performed at a frequency of 1 push min~-1 on a magnetic particle brake treadmill and a high-inertia push-cart. Eight male industrial workers performed a 40 min treadmill pushing task in the Context of a larger experiment and two, 2 h push-cart tasks with a unique water Loading system. A psychophysical methodology was employed, whereby the Subjects were asked to select a workload they could sustain for 8 h without Straining themselves or without becoming unusually tired, weakened, overheated Or out of breath.
