The relation between perceived exertion and physiological indicators of exertion during exercise was studied. HR (heart rate) Vo2, (oxygen uptake) and blood lactate concentration were measured, and RPE (rating of perceived exertion) waa recorded at different work loads for 12 subjects working with a wheelbarrow, with lifting of weights, and on a bicycle ergometer. The results showed that RPE is related to HR in a fairly linear way irrespective of the kind of work. Differences in the level of perceived exertion in relation to heart rate were found between the different kinds of work. These differences were related, to some extent, to the amount of oxygen uptake and blood lactate concentration.
