ABSTRACT=<sec><title>Purpose</title><p>This study explored the effect of three different modes of resistance training on appetite hormones [leptin, ghrelin, cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1), and peptide tyrosine–tyrosine (PYY)], cardiometabolic and anthropometric measures in males with obesity.</p></sec><sec><title>Methods</title><p>Forty-four males with obesity (age: 27.5 ± 9.4 yrs.; mean weight: 93.2 ± 2.2 kg, body mass index: 32.9 ± 1.2 kg/m<sup>2</sup>) were randomized to traditional resistance training (TRT, <italic>n</italic> = 11), circuit resistance training (CRT, <italic>n</italic> = 11), interval resistance training (IRT, <italic>n</italic> = 11) or control (C, <italic>n</italic> = 11) groups. All resistance training groups received 50 min of supervised training per session, three days per week, for 12 weeks. Measurements were taken at baseline and after 12 weeks of training.</p></sec><sec><title>Results</title><p>Plasma levels of leptin, ghrelin, CCK, and PYY decreased significantly in all three different modalities of resistance training groups when compared to the control group (<italic>p</italic> &lt; 0.05). GLP-1 increased significantly in both CRT and IRT groups compared to TRT and C groups (<italic>p</italic> &lt; 0.05). Glucose-dependent insulinotropic polypeptide decreased significantly in CRT and IRT groups compared to the C group (<italic>p</italic> &lt; 0.05). Adiponectin levels increased significantly in all resistance training groups compared to the C group (<italic>p</italic> &lt; 0.05).</p></sec><sec><title>Conclusion</title><p>Overall, CRT and IRT protocols had the greatest impact on appetite hormones compared to individuals who engaged in TRT or did not exercise (C).</p></sec>
