Abstract

Hypertension is one of the most important factors in the development of cardiovascular disease (CVD) in obese or overweight individuals. Therefore, in this study, the effect of RESISTANCE EXERCISE intensity and volume on blood pressure and MYOCARDIAL OXYGEN COST were studied in obese girls after resistance training. Twenty four female obese students with a BMI greater than 30 kg/m2 and normotensive (age 20.62±1.43 years, weight 78.12±11.08 kg, height 160±5.06 cm and BMI 30.09± 3.09 kg/m2) volunteered to participate in this study. Subjects in a randomized crossover design performed four sessions of RESISTANCE EXERCISE consisted of bench press, leg press and leg extension. Exercise protocol consisted of two sessions of low volume (3 sets) with intensities of 30% (LVLI) and 70% (LVHI) of one repetition maximum (1RM) and two sessions with high volume (7 sets) and the intensity of 30% (HVLI) and 70% (HVHI) of1RM. Blood pressure, heart rate and MYOCARDIAL OXYGEN COST (the product of systolic pressure and heart rate) were measured before exercise, immediately after, and every 10 minutes until 60 minutes after each session. RESISTANCE EXERCISE with 70% of 1RM and volume of 7 set decreased SYSTOLIC BLOOD PRESSURE at 30 and 50 min after exercise compared to RESISTANCE EXERCISE with 70% of 1RM and volume of 3 set and resistance training with 30% 1RM intensity and 3 and 7 sets (p<0.05). DIASTOLIC BLOOD PRESSURE at 20, 40, 50 and 60 min after RESISTANCE EXERCISE with 70% intensity and volume of 7 set were lower compared to other protocols. Also, the cost of myocardial oxygen at 30 and 60 min after RESISTANCE EXERCISE with HVHI was lower than LVLI in obese girls (p<0.05). Based on the findings of this study can be advised RESISTANCE EXERCISE as a non-pharmacological approach to lowering blood pressure and MYOCARDIAL OXYGEN COST in obese individuals.
