[The correlations of somatotypes and the total ridge count in Russian men of the White Sea area].
Under investigation there were 158 Russian men of the city of Arkhangelsk and Arkhangelsk Province aged from 18 to 30 years. The total ridge count (TRC) and indices of the body constitution (according to V. M. Shevkunenko--A. M. Geselevich) were studied: relative length of the trunk (RLT), relative length of lower extremities, relative width of the shoulders and relative width of the pelvis. The hypothesis of normal distribution of these indices was confirmed by the chi-square criterion. The division into groups of dolicho- (DS), meso- and brachymorphic somatotypes (BS) was performed according to each sign and with special reference to limits X+/-S. Comparison of people of BS and DS groups has revealed significant differences only for RLT. The correlation coefficient proved to be valuable exceptionally for RLT. The method of succession analysis has shown that the least amount of observations for the determination of significant differences according to TRC is required in somatotyping according to RLT. Further investigations with other parameters of somatotyping require considerable amount of observations. The correlation analysis has determined the significant correlation coefficient for RLT only. A conclusion is made of the correlation of finger patterns and TRC with the rate of growing processes of organism.
