Methodology to determine time allowance by work sampling using heart rate

An experimental work sampling study was performed using newly available technology in order to determine the allowance time of the task in the workday. In this study, heart rate measuring equipment was used on workers performing their activities during the work period while in parallel a traditional wok sampling study was performed. With this research it is possible to define a person's load work range (light, moderate and heavy) according to heart rate vs. activity performed, and on that basis, to determine the task allowance percentage. This proposed work sampling study method has better results for dynamic tasks, in other words when the operations require the entire body and/or walking.
