Abstract

Background and Objective: To establish a balance between work (physical exercise) and human
beings, the aerobic capacity (VO2 max) could be used as a measure. Additionally, the subjective
and physiological assessment could be applied as one of the methods for assessing physical
exercise. The most commonly used tools for the assessment of fatigue during physical exercise
include the Borg scale Rating of perceived Exertion (RPE) in relation to subjective symptoms
and heart rate (HR) in relation to physiological symptoms. The study is aimed to investigate
the relationship between the aerobic capacity and the RPE based on the measurement of
heat rate (HR) of workers from the Metal Industries of Isfahan. Materials and Methods: The
subjects were 200 male workers from metal components manufacturers in Isfahan selected
by using random sampling based on statistic method. The subjects were examined by using
ergometer in accordance with A strand 6 minutes cycle test protocol. Furthermore, the subjects
were 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 each
minutes. Results: Statistical analysis showed that there was a significant relationship between
the RPE and the aerobic capacity (VO2 max) (r = –0.904, P < 0.05). The results illustrated
that there was a stronger correlation between HR and VO2 max (r = 0.991, P < 0.001). The
regression analysis of the quadratic equation also indicated that there was also a significant
relationship between the VO2 max and HR. Conclusions: The results indicated that there was a
strong relationship between the RPE and VO2 max, as well as a greater correlation between HR
and VO2 max. Therefore, the HR could be used as a Prediction measure to estimate VO2 max.
