Background & objectives: One of the main problems for personnel of military and various industries, depending on their type of activity, is their thermal strain. The aim of this study was to investigate the relationship between the rate of perceived exertion with heart rate and deep temperature in laboratory condition for evaluating the thermal strain.
Methods: This experimental and cross sectional study was conducted on 13 male in five different temperatures (21, 24, 27, 30 and 35ºC). The tests were performed in climate test chamber on treadmill with light (2.4 kph), intermediate (4.8 kph) and heavy physical activities (6.3 kph). The samples were selected with simple random sampling method. The rate of perceived exertion, heart rate and oral temperature were measured and recorded. Finally, the Pearson correlation test and regression analysis were used to analyze the correlation between the variables.
Results: Pearson correlation test showed a high correlation between the rate of perceived exertion and oral temperature (r=0.88, p=0.01). There was a very high correlation between heart rate and severity of perceived exertion (r=0.91, p=0.01). Also, a high correlation was observed between the rate of perceived exertion and wet bulb globe temperature (r=089, p=0.01). The most heart rate and deep (oral) temperature were 159 and 38.5 in heavy activity, respectively.
Conclusion: The results of this study showed that the rate of perceived exertion had the high correlations with heart rate and oral temperature. This rating can be used as an easy and simple tool for evaluating the thermal strain.
Keywords: Ratings of Perceived Exertion, Heart Rate, Thermal Strain, Deep Temperature
