The training program spanned 12 weeks and was conducted with three sessions per week. Blood samples were collected 72 hours before and 72 hours after the 12-week training programs. These blood samples were transferred to specialized plasma test tubes containing EDTA and were then centrifuged at 10 rpm for 10 minutes.</span></span><br> <br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:"><b>Findings</b>: A significant decrease in Apo B levels (P < 0.0001) and an increase in Apo A levels (P < 0.05) were observed in the low-intensity training group compared to the control group. Additionally, a significant decrease in Apo J levels was observed in all exercise training groups compared to the control group (P < 0.05).</span></span><br> <span style="font-size:9pt"><span minion="" pro="" style="font-family:">Discussion & Conclusion: The findings of this study suggest that circuit resistance training, particularly at lower intensities, may lead to a reduction in the risk of cardiovascular diseases in obese individuals through the modification of Apo A, Apo B, and Apo J levels.</span></span></div> Circuit Resistance Training, Obese Men, Apolipoprotein, Training Intensity 1 11 http://jbrms.medilam.ac.ir/browse.php?a_code=A-10-302-2&slc_lang=en&sid=1 Mahdi Rezaei Mahbobi mahdir2nf2021@gmail.com 10031947532846006925 0009-0002-0339-3287 No Department of Exercise Physiology and Corrective Movements, Faculty of Sport Sciences, Urmia University, Urmia, Iran Akbar Nouri-Habashi akbarnori52@gmail.com 10031947532846006926 10031947532846006926 Yes Department of Exercise Physiology and Corrective Movements, Faculty of Sport Sciences, Urmia University, Urmia, Iran
