Background and Objective: To establish a balance between work (physical exercise) and humanbeings, the aerobic capacity (VO2 max) could be used as a measure. Additionally, the subjectiveand physiological assessment could be applied as one of the methods for assessing physicalexercise. The most commonly used tools for the assessment of fatigue during physical exerciseinclude the Borg scale Rating of perceived Exertion (RPE) in relation to subjective symptomsand heart rate (HR) in relation to physiological symptoms. The study is aimed to investigatethe relationship between the aerobic capacity and the RPE based on the measurement ofheat rate (HR) of workers from the Metal Industries of Isfahan. Materials and Methods: Thesubjects were 200 male workers from metal components manufacturers in Isfahan selectedby using random sampling based on statistic method. The subjects were examined by usingergometer in accordance with A strand 6 minutes cycle test protocol. Furthermore, the subjectswere asked to rate their status based on the Borg rating scale at the end of each minute.Additionally, their heat rates were monitored and recorded automatically at the end of eachminutes. Results: Statistical analysis showed that there was a significant relationship betweenthe RPE and the aerobic capacity (VO2 max) (r = –0.904, P < 0.05). The results illustratedthat there was a stronger correlation between HR and VO2 max (r = 0.991, P < 0.001). Theregression analysis of the quadratic equation also indicated that there was also a significantrelationship between the VO2 max and HR. Conclusions: The results indicated that there was astrong relationship between the RPE and VO2 max, as well as a greater correlation between HRand VO2 max. Therefore, the HR could be used as a Prediction measure to estimate VO2 max.
