Original Article
<div style="text-align: justify;"><strong>Background. </strong>The effects of exercise intensity on the rating of perceived exertion (RPE) have been widely studied. However, in most of these studies, the contraction intensities were provided in a randomized order.<br>
<strong>Objectives. </strong>This study aimed to examine the influence of intensity order on RPE.<br>
<strong>Methods.</strong> During the first period, three trials of isometric contractions were performed at three different target intensities in the following order: 25%, 50%, 75% of maximal voluntary contraction (MVC) in group A and in the reverse order: 75%, 50%, 25% of MVC in group B. Each group’s intensity order provided during the first period was reversed during the second period. The RPE was measured at each target intensity.<br>
<strong>Results. </strong>There was a significant difference in the perceived intensity at 75% of MVC between groups during the first period. The perceived intensity of 75% of MVC in group A during the second period and group B during the first period was significantly lower than the target intensity.<br>
<strong>Conclusion. </strong>The order of exercise intensity affected the perceived exertion responses in this study. When establishing an exercise program consisting of varying intensities, practitioners should consider the order of intensity implementation.</div>
