[Gender difference in physical development and functional state of the cardiac-vascular system in children of 12 years old].
It was shown that physical development in the girls of 12 years old somewhat forestall the physical development in the boys of the same age. Average values of the height and massa in the girls of 12 years old are following: 1.57 m +/- 0.15 m and 45.8kg +/- 0.16 kg against 1.55 m +/- 0.04 m and 44.53 kg 0.13 kg in the boys. Average values of heart rate, end diastolic pressure and workability of the left ventriculus in the children of 12 years old are similar in boys and girls, and the average value of stroke volume and power of the left ventriculus in the boys are more. The conclusion was made that the effectivenes of the heart activity in the boys of 12 years old is more than in the girls of the same age.
