Abstract
The aim of this study was to investigate the effect of 6 weeks of resistance training on morphological indicators of untrained women's heart health. For this purpose, 20 sedentary females (22/6±18 years old, 162/3±6/5 cm height, 58±5/1 kg weight, 18/3±5/2% percentage of fat and the surface of body: 1/62±0/15 m2) were selected randomly and assigned to two experimental (n = 10) and control (n = 10) groups. The anthropometric indexes, body composition and echocardiogram testing were measured before and after 6 weeks of resistance training exercise. The exercise protocol consisted of six movements with weights 3 of 10 repetitions with 70-60% of the 1RM. The results showed that after 6 weeks of resistance training exercise thickness of ventricular wall increased 10% and left ventricular end-systolic size decreased 10% (p?0/05) compared with the control group. But other indicators didn't change significantly. Thus, the results showed that 6 weeks of resistance training using weights, despite significant effect on some of the test, could possibly increase performance and heart healthy of untrained women who participated in our study.
