ABSTRACT
Background and aim: In order to establish appropriateness between labor and Human, aerobic capacity can be used. The methods which were used in physical labor are mental and physiological assessments. Subjective symptoms of fatigue during physical work are assessed with the Borg scale [RPE] and physiological with heart rate as well. This study aimed to compare the estimation of aerobic capacity [vo2max] with mental conception and physiology among male nurses in one of Tehran's hospitals.
Method: The present study was a cross sectional analysis. In this study a number of male nurses have participated randomly and by the means of ergo meter were assessed according to Strand protocol. Aerobic capacity was determined by the formula ACSM. Meanwhile at the end of each minute, the intensity of perceived effort [RPE], as well as heart rate are calculated and recorded.
Result: Statistical analysis showed that between aerobic capacity and RPE are significant relationship [P<0.005], [r=-0.84]. And according to the results relationship of heart rate with aerobic capacity has more correlation [P<0.005], [r=-0.9].Therefore the regression analysis of quadratic equation showed that there is a significant relationship between aerobic capacity and heart rate.
Conclusion:The results showed that the subjective assessments of individuals with aerobic capacity are high and there has been more relation between physiological assessment and aerobic capacity. In other words, a more reliable measure of heart rate in the aerobic capacity is estimated, so we can use heart rate as a physiological factor used to estimate aerobic capacity of individuals. The monitoring is done to individuals assigned to work with physical capacity to be deployed
