The aim of this study was to investigate the cardiac function of overweight girls after performing combined training and consuming kefir buttermilk.</p> <p style="text-align: left;"><strong>Materials and Methods:</strong> 40 non-athlete women with an age range of 20-30 years and a body mass index of 25-30 kg/m2 were selected using available methods. The subjects were randomly divided into 4 groups of 10 people, combined training, kefir buttermilk consumption, combined training interaction and kefir buttermilk and control group. The training groups participated in combined resistance and endurance trainings three days a week for 8 weeks. Buttermilk consumption groups consumed 450 ml of kefir buttermilk daily with meals. Analysis of covariance and Tukey's post hoc test were used p&le;0.05.</p> <p style="text-align: left;"><strong>Results:</strong> The results showed that following combined training and consumption of kefir buttermilk, the heart rate, P-R interval and T wave voltage of overweight girls decreased and increased significantly compared to the control group, respectively, and these changes were greater in the training group and consumption of buttermilk than the training group. These three heart variables in the buttermilk consumption group also decreased and increased respectively, but it was not significant compared to the control group.</p> <p style="text-align: left;"><strong>Conclusion:</strong> : Combined training along with consumption of kefir buttermilk can lead to improvement of heart function in overweight girls.</p> http://jspac.etb.iau.ir/en/Article/Download/47870
