Abstract
Background: Today, ultrasonography has become the main tool used for the evaluation of fetal anomalies. The aim of this study was to evaluate fetal heart rate changes immediately after combined two- and 4-dimensional ultrasound.
Materials and Methods: This study was performed on 191 pregnant women aged 15 to 45 years old who were referred for 4-dimensional ultrasonography in summer 2013. Before the onset of 2-dimensional ultrasonography, baseline fetal heart rate was measured by ultrasound. At the same time, the maternal heart rate was recorded during one minute. Then, combined ultrasonography was performed and same parameters were recorded at the end.
Results: Maternal heart rate significantly decreased after combined ultrasonography (p=0.0001). Fetal heart rate did not differ before and after ultrasonography (p=0.693).
Conclusion: Four-dimensional ultrasonography has no effect on fetal heart as an indicator for evaluating the fetus temperature.

Abstract
Background: In recent years, studies have been conducted on the role of coenzyme Q10 in improvement of sport performance and also cardiovascular health. The present study investigate effect of coenzyme Q10 supplementation combined with swimming aerobic exercises on Heart Rate Deflection Point (HRDP) and VO2max in active women.
Materials and Methods: A number of 32 trained women with the average age of 21/25 ± 0.86 years and Body Mass Index (BMI) of 20/127± 1.06 kg/square meter were selected randomly and were divided into eight -member each groups: Control, Supplement, Supplement – Exercise and Exercise. The subjects participated in four-week consumption of coenzyme Q10 and swimming exercises (three sessions in a week).The consumption rate of coenzyme Q10 100 mg/kg/d was in the form of capsule that subjects took it during lunchtime. Before and after a four-week period, the subjects performed an incremental exhaustive test on treadmill, using respiratory gas analyzer to determine HRDP and VO2max. It should be noted that data analysis was conducted using One-Way Variance Analysis Test (ANOVA) in P<0.05 significant level.
Results: Based on paired T-Test results, despite HRDP had increased in each four groups but the significant increase was observed only among groups in VO2max (P=0.008) based on ANOVA Test (P<0.05).
Conclusion: Although positive changes were observed inside the group after passage of four weeks, coenzyme Q10 supplementation combined with swimming aerobic exercise had not any significant effect on HRDP only increased VO2max.

Abstract
Background: High blood pressure increases various cardiovascular events about 2 to 3 times in a person. The purpose of this study is to recognize the effect of a course of pilates exercise on hypertension, nitric oxide, and resting heart rate in the eldrlymen with hypertension.
Materials and Methods: Subjects of this quasi-experimental research included 30 elderly men with hypertension grade one(in the range of systolic-diastolic 140/90 to 159/99mm Hg) who participated voluntarily and accessibly in the study and were divided randomly into two experimental peer (15 people) and control (15 people) groups. Weight, height and BMI of subjects were 75±80, 170±175 and 25-26, respectively. The experimental group did selected exercise of Pilates for eight weeks (three one-hour sessions per week). Desired variables of the subjects of both groups were evaluated 24 hours before the start of exercise and 24 hours after the last session. Data analysis was conducted using dependent and independent t-test by SPSS16 statistical software at the significant level of p≥0.05.
Results: The research results showed that the eight-week pilates exercise gave rise to reduction in blood pressure(p≤0.05) as well as resting heart rate (p≤0.05) and to increase in nitric oxide of elderly men with hypertension (p≤0.05).
Conclusion: The eight-week pilates exercise reduced blood pressure and resting heart rate and increased the production of nitric oxide in elderly men. So, it seems that the regular physical exercise can be effective as a preventive factor in the outbreak of cardiovascular diseases of the elderly men.

Abstract
Background and Aim: Pregnancy and exercise training are associated with changes in the cardiovascular anatomy and physiology. There is a few studies on this issue in Iran. In this regard, the aim of this study is to assess the effect of a combined exercise training program on blood pressure and heart rate variability of pregnant women.
Methods & Materials: This randomized clinical trial was conducted in Shahid Akbarabadi Hospital in Tehran, Iran in 2019. Participants were 10 healthy pregnant women with a gestational age of 24-26 weeks in the interventional group and 10 healthy pregnant women in the control group. The interventional group received 8 weeks of combined exercise training at moderate intensity. The blood pressure measurement, electrocardiogram and aerobic and resistant exercise tests of samples were performed before and after training. AST3000 Avicenna software was used to analyze the heart rate variability parameters, and for statistical analysis, paired and independent t-tests, Mann Whitney U, and Wilcoxon tests were used.
Ethical Considerations: This study with registered clinical trial code IRCT20190227042856N1 was approved by the Research Ethics Committee of Islamic Azad University of Science and Research Branch in Tehran, Iran (code: IR.IAU.SRB.REC.1397.101).
Results: The mean systolic and diastolic blood pressure levels were lower in the interventional group by the 34th week of pregnancy compared to the control group (P<0.05). The mean of time-domain parameters in the interventional group were higher by the 34th week of pregnancy compared to the control group (P<0.05).
Conclusion: Combined exercise training can improve autonomic and parasympathetic nervous systems in pregnant women.
