The work deals with two series of male students measured in the years 1927 and 1987/88. The first group was presented in the work of B. Skerlj Prispevek k antropologii Jihoslovanu. He measured 34 parameters on 60 Jugoslave students, studied in the University of Prague before 2nd World war. Their age was between 17 and 31 years. The second group was the representative series of first year students of the University of Ljubljana included in the research project: Morphological variability of the students of the University of Ljubljana in the years 1987/88. There were 344 male students between 19 and 21 years. We could compare only the parameters for which we were sure that was taken by the same technique - Martin's technique. Those were the following parameters: stature, sitting height jugular height, iliospinale height, biacromial, bicristal and bitrochanteric breadth, saggital and transverzal dimensions of chest, length and breadth of hand and foot and weight. We calculated basic statistics mean value, standard deviation and as in the work of Skerlj arranged the material according to Martin to five groups: type T (mean value) and -B, -A +A and +B calculated with + or -1/2 or 1 SD. The 60 years differences between both series of students show positive secular trend in stature with 4.7 cm increase, sitting height with 1.6 cm, jugular height with 4.2 cm and iliospinale height with 4.4 cm higher mean values. Those results indicates that the intensity of changes was greater on extremities than on the trunk. Except biacromial breadth, other breadths decreased. In the serie 1927 also parameters of hand and foot were greater except hand length, which was greater in 1987 for 2.3 cm. The difference of 9.3 kg in mean value of weight was greater than we expected. The reason for this could be the fact, that students in Prague loosed about 10 kg during first weeks of their stay in the new environment. Our analysis has shown, that nowadays students in Ljubljana follows the trend and intensity of last decades changes. Further systematic researches on students population will be necessary. The results are shown in Table 1, Table 2 and Table 3.
