Effects of Endurance and Circuit Resistance Trainings on Lipid Profile, Heart Rate, and Hematological Parameters in Obese Male Students

Studies have shown that different exercise ways are of the most important factors that affect cardiovascular risk factors and hematological parameters. This present paper aims to study the effects of two methods of endurance and resistance training on lipid profiles, heart rate, and hematological parameters in obese male students. 36 obese students were purposefully selected and randomly divided into three groups of 12 including endurance exercise, resistance exercise, and control. Exercise program was performed 3 times a week for 8 weeks, with a specific duration and intensity in both endurance and resistance exercise groups. Blood sampling was done after 14 fasting before the trial and 48 hours after the last training session. Results showed that both resistance and endurance exercises significantly increased HDL-C, Hct, and Hb and significantly decreased TC, TG, and resting heart rate (P>0.05). Also, Resistance exercise significantly increased the PLT and decreased LDL-C (P>0.05). However, WBC and RBC showed no significant change in the resistance and endurance exercise groups (P>0.05). In addition, no significant difference was observed between endurance and resistance exercise (P>0.05). In general, both endurance and resistance exercises can affect the lipid profile and hematological parameters and also reduce the resting heart rate. Therefore, they can be considered as an appropriate and non-medication approaches to prevent and reduce the incidence of cardiovascular diseases and obesity-related disorders in obese male adolescents.
