Work Physiology Evaluation of Laundry Workers

摘要

This study aimed to assess cardiovascular strain during laundry operations in terms of physical workload, based on heart rate changes and level of pain complaints. Researchers measured resting and working heart rates and calculated cardiovascular load (%CVL), cardiovascular strain (%CVS), reserve heart rate (%RHR), energy expenditure, oxygen consumption, and measure level of pain complain in 6 laundry workers using Nordic Body Map questionnaire (NBM). Based on the result of %CVL and %CVS, the work in laundry was classified as acceptable level. Similarly, a high-level category was recorded for %RHR in moderate of energy expenditure. However, there are very pain level complain for hand using NBM questionnaire. Thus, there is a need to redesign the work content of equipment used and keep the physical workload in acceptable level, as this will increase their productivity and reduce their health risk.
