ABSTRACT=<p><bold>Purpose:</bold> The aim of the study is to compare the effect of resistance training volume on inhibitory control in young adults with previous experience in resistance training.</p><p><bold>Method:</bold> All the 27 participants underwent 40-week experiment, divided in three training phases of 8-week duration. A washout period of 8 weeks between each of the training phases was carried out. The participants performed 1, 3, or 5 sets of the same exercises with equalized intensity (loading zones) and rest. Inhibitory control was assessed by the Stroop Test.</p><p><bold>Results:</bold> Interaction effect was found for inhibitory control accuracy [<italic>F</italic><sub>(5,22)</sub> = 56.88, <italic>p</italic> &lt; 0.01] and mean response time [<italic>F</italic><sub>(5,22)</sub> = 83.02, <italic>p</italic> &lt; 0.01] for 3 sets (<italic>p</italic> = 0.01; ES = 0.6) and 5 sets (<italic>p</italic> = 0.01; ES = 0.8) when compared to 1 set.</p><p><bold>Conclusion:</bold> In conclusion, 1 set of resistance training may provide insufficient volume stimulus for positive adaptation in inhibitory control when compared to 3 or 5 sets.</p>
