Abstract :

Background: The aim of the current research was the effect of 8 weeks of increasing resistance training and a period of non-training after that on the left ventricular LVEVD index of sedentary women. Method: In this semi-experimental research that was conducted in a field-laboratory manner, 32 sedentary women who were able to regularly participate in the exercise protocol were selected by simple random sampling and randomly divided into 2 groups: 1- Resistance exercise group (16 people ), 2- control group (16 people). In the present study, before the implementation of the training program, all the anthropometric characteristics, body composition and structural and functional indicators of the left ventricle of the subjects were measured and recorded in three stages under the same conditions. Variable left ventricular end-diastolic volume (LVEDV), by a cardiologist with echocardiography using M-Mode, Spectral Doppler, Color Doppler (2-D) methods and in a special echocardiography room in 3 stages (before exercise, after the end of 8 weeks The resistance training program was measured after 4 weeks of non-training after training. It was also measured before echocardiography. All training programs including 3 training days per week and every day for 90 minutes were implemented in the sports hall of Azad University, Yazd branch. This program was implemented for 8 weeks from low to high intensity, taking into account the principle of overload and increasing the intensity of training. Results: the results showed that eight weeks of increasing resistance training was significant on the left ventricular end-diastolic volume (LVEDV) of sedentary women Conclusion: Increasing resistance training reduced the positive effects of increasing resistance training on the left ventricular end-diastolic volume.
