[The indices of physical development and cardiovascular system adaptation in Vladivostok medical university students].

Height-weight ratios were measured in 190 high medical students (98 youths and 92 girls at the age of 18 to 21 years). At the same time the growth rates were in agreement with the average statistical normal values, underweight was detected in 32% of the youths and in 21% of the girls. There was a direct relation of systolic blood pressure in both youths and girls and an inverse relation of heart rate to the body mass index. Although the examinees were apparently healthy individuals, half of them were found to have sinus nodal regulatory stress, as evidenced by analysis of variance for cardiac rhythms.
