This paper presents the results of a study to determine the differences in the heart rate and subjective perception of fatigue levels in trained and untrained workers performing manual handling jobs. Ten trained workers and 10 untrained office workers of an organisation participated in the study. Workers were asked to perform a manual handling job of lifting and lowering 8kg boxes at 12 repetitions per minute. Investigations of heart rate and subjective perception of fatigue level revealed statistically significant differences between trained and untrained workers. Untrained workers showed heart rates and fatigue levels higher by 25% and 65% respectively. These results have implication for pre-employment training of workers expected to perform manual handling jobs.
